If - * there are more than corePoolSize but less than maximumPoolSize - * threads running, a new thread will be created only if the queue is - * full. By setting corePoolSize and maximumPoolSize the same, you - * create a fixed-size thread pool. By setting maximumPoolSize to an - * essentially unbounded value such as {@code Integer.MAX_VALUE}, you - * allow the pool to accommodate an arbitrary number of concurrent - * tasks. Most typically, core and maximum pool sizes are set only - * upon construction, but they may also be changed dynamically using - * {@link #setCorePoolSize} and {@link #setMaximumPoolSize}. </dd> - * - * <dt>On-demand construction</dt> - * - * <dd> By default, even core threads are initially created and - * started only when new tasks arrive, but this can be overridden - * dynamically using method {@link #prestartCoreThread} or {@link - * #prestartAllCoreThreads}.

If not - * otherwise specified, a {@link Executors#defaultThreadFactory} is - * used, that creates threads to all be in the same {@link - * ThreadGroup} and with the same {@code NORM_PRIORITY} priority and - * non-daemon status. By supplying a different ThreadFactory, you can - * alter the thread's name, thread group, priority, daemon status, - * etc. If a {@code ThreadFactory} fails to create a thread when asked - * by returning null from {@code newThread}, the executor will - * continue, but might not be able to execute any tasks. Threads - * should possess the "modifyThread" {@code RuntimePermission}. If - * worker threads or other threads using the pool do not possess this - * permission, service may be degraded: configuration changes may not - * take effect in a timely manner, and a shutdown pool may remain in a - * state in which termination is possible but not completed.</dd> - * - * <dt>Keep-alive times</dt> - * - * <dd>If the pool currently has more than corePoolSize threads, - * excess threads will be terminated if they have been idle for more - * than the keepAliveTime (see {@link #getKeepAliveTime}). This - * provides a means of reducing resource consumption when the pool is - * not being actively used. If the pool becomes more active later, new - * threads will be constructed. This parameter can also be changed - * dynamically using method {@link #setKeepAliveTime}. Using a value - * of {@code Long.MAX_VALUE} {@link TimeUnit#NANOSECONDS} effectively - * disables idle threads from ever terminating prior to shut down. By - * default, the keep-alive policy applies only when there are more - * than corePoolSizeThreads. But method {@link - * #allowCoreThreadTimeOut(boolean)} can be used to apply this - * time-out policy to core threads as well, so long as the - * keepAliveTime value is non-zero. </dd> - * - * <dt>Queuing</dt> - * - * <dd>Any {@link BlockingQueue} may be used to transfer and hold - * submitted tasks. The use of this queue interacts with pool sizing: - * - * <ul> - * - * <li> If fewer than corePoolSize threads are running, the Executor - * always prefers adding a new thread - * rather than queuing.</li> - * - * <li> If corePoolSize or more threads are running, the Executor - * always prefers queuing a request rather than adding a new - * thread.</li> - * - * <li> If a request cannot be queued, a new thread is created unless - * this would exceed maximumPoolSize, in which case, the task will be - * rejected.</li> - * - * </ul> - * - * There are three general strategies for queuing: - * <ol> - * - * <li> <em> Direct handoffs.</em> A good default choice for a work - * queue is a {@link SynchronousQueue} that hands off tasks to threads - * without otherwise holding them. Here, an attempt to queue a task - * will fail if no threads are immediately available to run it, so a - * new thread will be constructed. This policy avoids lockups when - * handling sets of requests that might have internal dependencies. - * Direct handoffs generally require unbounded maximumPoolSizes to - * avoid rejection of new submitted tasks. This in turn admits the - * possibility of unbounded thread growth when commands continue to - * arrive on average faster than they can be processed. </li> - * - * <li><em> Unbounded queues.</em> Using an unbounded queue (for - * example a {@link LinkedBlockingQueue} without a predefined - * capacity) will cause new tasks to wait in the queue when all - * corePoolSize threads are busy. Thus, no more than corePoolSize - * threads will ever be created. (And the value of the maximumPoolSize - * therefore doesn't have any effect.) This may be appropriate when - * each task is completely independent of others, so tasks cannot - * affect each others execution; for example, in a web page server. - * While this style of queuing can be useful in smoothing out - * transient bursts of requests, it admits the possibility of - * unbounded work queue growth when commands continue to arrive on - * average faster than they can be processed. </li> - * - * <li><em>Bounded queues.</em> A bounded queue (for example, an - * {@link ArrayBlockingQueue}) helps prevent resource exhaustion when - * used with finite maximumPoolSizes, but can be more difficult to - * tune and control. Queue sizes and maximum pool sizes may be traded - * off for each other: Using large queues and small pools minimizes - * CPU usage, OS resources, and context-switching overhead, but can - * lead to artificially low throughput. If tasks frequently block (for - * example if they are I/O bound), a system may be able to schedule - * time for more threads than you otherwise allow. Use of small queues - * generally requires larger pool sizes, which keeps CPUs busier but - * may encounter unacceptable scheduling overhead, which also - * decreases throughput. </li> - * - * </ol> - * - * </dd> - * - * <dt>Rejected tasks</dt> - * - * <dd> New tasks submitted in method {@link #execute} will be - * <em>rejected</em> when the Executor has been shut down, and also - * when the Executor uses finite bounds for both maximum threads and - * work queue capacity, and is saturated. In either case, the {@code - * execute} method invokes the {@link - * RejectedExecutionHandler#rejectedExecution} method of its {@link - * RejectedExecutionHandler}. Four predefined handler policies are - * provided: - * - * <ol> - * - * <li> In the default {@link ThreadPoolExecutor.AbortPolicy}, the - * handler throws a runtime {@link RejectedExecutionException} upon - * rejection. </li> - * - * <li> In {@link ThreadPoolExecutor.CallerRunsPolicy}, the thread - * that invokes {@code execute} itself runs the task. This provides a - * simple feedback control mechanism that will slow down the rate that - * new tasks are submitted. </li> - * - * <li> In {@link ThreadPoolExecutor.DiscardPolicy}, a task that - * cannot be executed is simply dropped. </li> - * - * <li>In {@link ThreadPoolExecutor.DiscardOldestPolicy}, if the - * executor is not shut down, the task at the head of the work queue - * is dropped, and then execution is retried (which can fail again, - * causing this to be repeated.) </li> - * - * </ol> - * - * It is possible to define and use other kinds of {@link - * RejectedExecutionHandler} classes. Doing so requires some care - * especially when policies are designed to work only under particular - * capacity or queuing policies. </dd> - * - * <dt>Hook methods</dt> - * - * <dd>This class provides {@code protected} overridable {@link - * #beforeExecute} and {@link #afterExecute} methods that are called - * before and after execution of each task. These can be used to - * manipulate the execution environment; for example, reinitializing - * ThreadLocals, gathering statistics, or adding log - * entries. Additionally, method {@link #terminated} can be overridden - * to perform any special processing that needs to be done once the - * Executor has fully terminated. - * - * <p>If hook or callback methods throw exceptions, internal worker - * threads may in turn fail and abruptly terminate.</dd> - * - * <dt>Queue maintenance</dt> - * - * <dd> Method {@link #getQueue} allows access to the work queue for - * purposes of monitoring and debugging. Use of this method for any - * other purpose is strongly discouraged. Two supplied methods, - * {@link #remove} and {@link #purge} are available to assist in - * storage reclamation when large numbers of queued tasks become - * cancelled.</dd> - * - * <dt>Finalization</dt> - * - * <dd> A pool that is no longer referenced in a program <em>AND</em> - * has no remaining threads will be {@code shutdown} automatically. If - * you would like to ensure that unreferenced pools are reclaimed even - * if users forget to call {@link #shutdown}, then you must arrange - * that unused threads eventually die, by setting appropriate - * keep-alive times, using a lower bound of zero core threads and/or - * setting {@link #allowCoreThreadTimeOut(boolean)}. </dd> - * - * </dl> - * - * <p> <b>Extension example</b>.

- -import scala.actors.threadpool.TimeUnit; - -/** - * {@code Lock} implementations provide more extensive locking - * operations than can be obtained using {@code synchronized} methods - * and statements. They allow more flexible structuring, may have - * quite different properties, and may support multiple associated - * {@link Condition} objects. - * - * <p>A lock is a tool for controlling access to a shared resource by - * multiple threads. Commonly, a lock provides exclusive access to a - * shared resource: only one thread at a time can acquire the lock and - * all access to the shared resource requires that the lock be - * acquired first. However, some locks may allow concurrent access to - * a shared resource, such as the read lock of a {@link ReadWriteLock}. - * - * <p>The use of {@code synchronized} methods or statements provides - * access to the implicit monitor lock associated with every object, but - * forces all lock acquisition and release to occur in a block-structured way: - * when multiple locks are acquired they must be released in the opposite - * order, and all locks must be released in the same lexical scope in which - * they were acquired. - * - * <p>While the scoping mechanism for {@code synchronized} methods - * and statements makes it much easier to program with monitor locks, - * and helps avoid many common programming errors involving locks, - * there are occasions where you need to work with locks in a more - * flexible way. For example, some algorithms for traversing - * concurrently accessed data structures require the use of - * "hand-over-hand" or "chain locking": you - * acquire the lock of node A, then node B, then release A and acquire - * C, then release B and acquire D and so on. Implementations of the - * {@code Lock} interface enable the use of such techniques by - * allowing a lock to be acquired and released in different scopes, - * and allowing multiple locks to be acquired and released in any - * order. - * - * <p>With this increased flexibility comes additional - * responsibility. The absence of block-structured locking removes the - * automatic release of locks that occurs with {@code synchronized} - * methods and statements. In most cases, the following idiom - * should be used: - * - * <pre><tt> Lock l = ...; - * l.lock(); - * try { - * // access the resource protected by this lock - * } finally { - * l.unlock(); - * } - * </tt></pre> - * - * When locking and unlocking occur in different scopes, care must be - * taken to ensure that all code that is executed while the lock is - * held is protected by try-finally or try-catch to ensure that the - * lock is released when necessary. - * - * <p>{@code Lock} implementations provide additional functionality - * over the use of {@code synchronized} methods and statements by - * providing a non-blocking attempt to acquire a lock ({@link - * #tryLock()}), an attempt to acquire the lock that can be - * interrupted ({@link #lockInterruptibly}, and an attempt to acquire - * the lock that can timeout ({@link #tryLock(long, TimeUnit)}). - * - * <p>A {@code Lock} class can also provide behavior and semantics - * that is quite different from that of the implicit monitor lock, - * such as guaranteed ordering, non-reentrant usage, or deadlock - * detection. If an implementation provides such specialized semantics - * then the implementation must document those semantics. - * - * <p>Note that {@code Lock} instances are just normal objects and can - * themselves be used as the target in a {@code synchronized} statement. - * Acquiring the - * monitor lock of a {@code Lock} instance has no specified relationship - * with invoking any of the {@link #lock} methods of that instance. - * It is recommended that to avoid confusion you never use {@code Lock} - * instances in this way, except within their own implementation. - * - * <p>Except where noted, passing a {@code null} value for any - * parameter will result in a {@link NullPointerException} being - * thrown. - * - * <h3>Memory Synchronization</h3> - * - * <p>All {@code Lock} implementations <em>must</em> enforce the same - * memory synchronization semantics as provided by the built-in monitor - * lock, as described in <a href="http://java.sun.com/docs/books/jls/"> - * The Java Language Specification, Third Edition (17.4 Memory Model)</a>: - * <ul> - * <li>A successful {@code lock} operation has the same memory - * synchronization effects as a successful <em>Lock</em> action. - * <li>A successful {@code unlock} operation has the same - * memory synchronization effects as a successful <em>Unlock</em> action. - * </ul> - * - * Unsuccessful locking and unlocking operations, and reentrant - * locking/unlocking operations, do not require any memory - * synchronization effects. - * - * <h3>Implementation Considerations</h3> - * - * <p> The three forms of lock acquisition (interruptible, - * non-interruptible, and timed) may differ in their performance - * characteristics, ordering guarantees, or other implementation - * qualities.

Can it acquire a read lock while holding the - * write lock? Is the read lock itself reentrant? - * - * <li>Can the write lock be downgraded to a read lock without allowing - * an intervening writer?

A nonfair lock that is continuously contended may - * indefinitely postpone one or more reader or writer threads, but - * will normally have higher throughput than a fair lock. - * <p> - * - * DEPARTURE FROM java.util.concurrent: this implementation impose - * a writer-preference and thus its acquisition order may be different - * than in java.util.concurrent. - * - * <li><b>Reentrancy</b> - * - * <p>This lock allows both readers and writers to reacquire read or - * write locks in the style of a {@link ReentrantLock}. Non-reentrant - * readers are not allowed until all write locks held by the writing - * thread have been released. - * - * <p>Additionally, a writer can acquire the read lock, but not - * vice-versa. Among other applications, reentrancy can be useful - * when write locks are held during calls or callbacks to methods that - * perform reads under read locks. If a reader tries to acquire the - * write lock it will never succeed. - * - * <li><b>Lock downgrading</b> - * <p>Reentrancy also allows downgrading from the write lock to a read lock, - * by acquiring the write lock, then the read lock and then releasing the - * write lock. However, upgrading from a read lock to the write lock is - * <b>not</b> possible. - * - * <li><b>Interruption of lock acquisition</b> - * <p>The read lock and write lock both support interruption during lock - * acquisition. - * - * <li><b>{@link Condition} support</b> - * <p>The write lock provides a {@link Condition} implementation that - * behaves in the same way, with respect to the write lock, as the - * {@link Condition} implementation provided by - * {@link ReentrantLock#newCondition} does for {@link ReentrantLock}. - * This {@link Condition} can, of course, only be used with the write lock. - * - * <p>The read lock does not support a {@link Condition} and - * {@code readLock().newCondition()} throws - * {@code UnsupportedOperationException}. - * - * <li><b>Instrumentation</b> - * <p>This class supports methods to determine whether locks - * are held or contended. These methods are designed for monitoring - * system state, not for synchronization control. - * </ul> - * - * <p>Serialization of this class behaves in the same way as built-in - * locks: a deserialized lock is in the unlocked state, regardless of - * its state when serialized. - * - * <p><b>Sample usages</b>. Here is a code sketch showing how to exploit - * reentrancy to perform lock downgrading after updating a cache (exception - * handling is elided for simplicity): - * <pre> - * class CachedData { - * Object data; - * volatile boolean cacheValid; - * ReentrantReadWriteLock rwl = new ReentrantReadWriteLock(); - * - * void processCachedData() { - * rwl.readLock().lock(); - * if (!cacheValid) { - * // Must release read lock before acquiring write lock - * rwl.readLock().unlock(); - * rwl.writeLock().lock(); - * // Recheck state because another thread might have acquired - * // write lock and changed state before we did. - * if (!cacheValid) { - * data = ... - * cacheValid = true; - * } - * // Downgrade by acquiring read lock before releasing write lock - * rwl.readLock().lock(); - * rwl.writeLock().unlock(); // Unlock write, still hold read - * } - * - * use(data); - * rwl.readLock().unlock(); - * } - * } - * </pre> - * - * ReentrantReadWriteLocks can be used to improve concurrency in some - * uses of some kinds of Collections. This is typically worthwhile - * only when the collections are expected to be large, accessed by - * more reader threads than writer threads, and entail operations with - * overhead that outweighs synchronization overhead. For example, here - * is a class using a TreeMap that is expected to be large and - * concurrently accessed. - * - * <pre>{@code - * class RWDictionary { - * private final Map<String, Data> m = new TreeMap<String, Data>(); - * private final ReentrantReadWriteLock rwl = new ReentrantReadWriteLock(); - * private final Lock r = rwl.readLock(); - * private final Lock w = rwl.writeLock(); - * - * public Data get(String key) { - * r.lock(); - * try { return m.get(key); } - * finally { r.unlock(); } - * } - * public String[] allKeys() { - * r.lock(); - * try { return m.keySet().toArray(); } - * finally { r.unlock(); } - * } - * public Data put(String key, Data value) { - * w.lock(); - * try { return m.put(key, value); } - * finally { w.unlock(); } - * } - * public void clear() { - * w.lock(); - * try { m.clear(); } - * finally { w.unlock(); } - * } - * }}</pre> - * - * <h3>Implementation Notes</h3> - * - * <p>This lock supports a maximum of 65535 recursive write locks - * and 65535 read locks.

Preference rules give - * first priority to processing tasks from their own queues (LIFO - * or FIFO, depending on mode), then to randomized FIFO steals of - * tasks in other queues. - * - * WorkQueues - * ========== - * - * Most operations occur within work-stealing queues (in nested - * class WorkQueue). These are special forms of Deques that - * support only three of the four possible end-operations -- push, - * pop, and poll (aka steal), under the further constraints that - * push and pop are called only from the owning thread (or, as - * extended here, under a lock), while poll may be called from - * other threads. (If you are unfamiliar with them, you probably - * want to read Herlihy and Shavit's book "The Art of - * Multiprocessor programming", chapter 16 describing these in - * more detail before proceeding.) The main work-stealing queue - * design is roughly similar to those in the papers "Dynamic - * Circular Work-Stealing Deque" by Chase and Lev, SPAA 2005 - * (http://research.sun.com/scalable/pubs/index.html) and - * "Idempotent work stealing" by Michael, Saraswat, and Vechev, - * PPoPP 2009 (http://portal.acm.org/citation.cfm?id=1504186). - * The main differences ultimately stem from GC requirements that - * we null out taken slots as soon as we can, to maintain as small - * a footprint as possible even in programs generating huge - * numbers of tasks. To accomplish this, we shift the CAS - * arbitrating pop vs poll (steal) from being on the indices - * ("base" and "top") to the slots themselves. So, both a - * successful pop and poll mainly entail a CAS of a slot from - * non-null to null. Because we rely on CASes of references, we - * do not need tag bits on base or top. They are simple ints as - * used in any circular array-based queue (see for example - * ArrayDeque). Updates to the indices must still be ordered in a - * way that guarantees that top == base means the queue is empty, - * but otherwise may err on the side of possibly making the queue - * appear nonempty when a push, pop, or poll have not fully - * committed. Note that this means that the poll operation, - * considered individually, is not wait-free. One thief cannot - * successfully continue until another in-progress one (or, if - * previously empty, a push) completes. However, in the - * aggregate, we ensure at least probabilistic non-blockingness. - * If an attempted steal fails, a thief always chooses a different - * random victim target to try next. So, in order for one thief to - * progress, it suffices for any in-progress poll or new push on - * any empty queue to complete. (This is why we normally use - * method pollAt and its variants that try once at the apparent - * base index, else consider alternative actions, rather than - * method poll.) - * - * This approach also enables support of a user mode in which local - * task processing is in FIFO, not LIFO order, simply by using - * poll rather than pop. This can be useful in message-passing - * frameworks in which tasks are never joined. However neither - * mode considers affinities, loads, cache localities, etc, so - * rarely provide the best possible performance on a given - * machine, but portably provide good throughput by averaging over - * these factors. (Further, even if we did try to use such - * information, we do not usually have a basis for exploiting it. - * For example, some sets of tasks profit from cache affinities, - * but others are harmed by cache pollution effects.) - * - * WorkQueues are also used in a similar way for tasks submitted - * to the pool. We cannot mix these tasks in the same queues used - * for work-stealing (this would contaminate lifo/fifo - * processing). Instead, we randomly associate submission queues - * with submitting threads, using a form of hashing. The - * ThreadLocal Submitter class contains a value initially used as - * a hash code for choosing existing queues, but may be randomly - * repositioned upon contention with other submitters. In - * essence, submitters act like workers except that they are - * restricted to executing local tasks that they submitted (or in - * the case of CountedCompleters, others with the same root task). - * However, because most shared/external queue operations are more - * expensive than internal, and because, at steady state, external - * submitters will compete for CPU with workers, ForkJoinTask.join - * and related methods disable them from repeatedly helping to - * process tasks if all workers are active. Insertion of tasks in - * shared mode requires a lock (mainly to protect in the case of - * resizing) but we use only a simple spinlock (using bits in - * field qlock), because submitters encountering a busy queue move - * on to try or create other queues -- they block only when - * creating and registering new queues. - * - * Management - * ========== - * - * The main throughput advantages of work-stealing stem from - * decentralized control -- workers mostly take tasks from - * themselves or each other. We cannot negate this in the - * implementation of other management responsibilities. The main - * tactic for avoiding bottlenecks is packing nearly all - * essentially atomic control state into two volatile variables - * that are by far most often read (not written) as status and - * consistency checks. - * - * Field "ctl" contains 64 bits holding all the information needed - * to atomically decide to add, inactivate, enqueue (on an event - * queue), dequeue, and/or re-activate workers. To enable this - * packing, we restrict maximum parallelism to (1<<15)-1 (which is - * far in excess of normal operating range) to allow ids, counts, - * and their negations (used for thresholding) to fit into 16bit - * fields. - * - * Field "plock" is a form of sequence lock with a saturating - * shutdown bit (similarly for per-queue "qlocks"), mainly - * protecting updates to the workQueues array, as well as to - * enable shutdown. When used as a lock, it is normally only very - * briefly held, so is nearly always available after at most a - * brief spin, but we use a monitor-based backup strategy to - * block when needed. - * - * Recording WorkQueues. WorkQueues are recorded in the - * "workQueues" array that is created upon first use and expanded - * if necessary. Updates to the array while recording new workers - * and unrecording terminated ones are protected from each other - * by a lock but the array is otherwise concurrently readable, and - * accessed directly. To simplify index-based operations, the - * array size is always a power of two, and all readers must - * tolerate null slots. Worker queues are at odd indices. Shared - * (submission) queues are at even indices, up to a maximum of 64 - * slots, to limit growth even if array needs to expand to add - * more workers. Grouping them together in this way simplifies and - * speeds up task scanning. - * - * All worker thread creation is on-demand, triggered by task - * submissions, replacement of terminated workers, and/or - * compensation for blocked workers. However, all other support - * code is set up to work with other policies. To ensure that we - * do not hold on to worker references that would prevent GC, ALL - * accesses to workQueues are via indices into the workQueues - * array (which is one source of some of the messy code - * constructions here). In essence, the workQueues array serves as - * a weak reference mechanism. Thus for example the wait queue - * field of ctl stores indices, not references. Access to the - * workQueues in associated methods (for example signalWork) must - * both index-check and null-check the IDs. All such accesses - * ignore bad IDs by returning out early from what they are doing, - * since this can only be associated with termination, in which - * case it is OK to give up. All uses of the workQueues array - * also check that it is non-null (even if previously - * non-null). This allows nulling during termination, which is - * currently not necessary, but remains an option for - * resource-revocation-based shutdown schemes. It also helps - * reduce JIT issuance of uncommon-trap code, which tends to - * unnecessarily complicate control flow in some methods. - * - * Event Queuing. Unlike HPC work-stealing frameworks, we cannot - * let workers spin indefinitely scanning for tasks when none can - * be found immediately, and we cannot start/resume workers unless - * there appear to be tasks available. On the other hand, we must - * quickly prod them into action when new tasks are submitted or - * generated. In many usages, ramp-up time to activate workers is - * the main limiting factor in overall performance (this is - * compounded at program start-up by JIT compilation and - * allocation). So we try to streamline this as much as possible. - * We park/unpark workers after placing in an event wait queue - * when they cannot find work. This "queue" is actually a simple - * Treiber stack, headed by the "id" field of ctl, plus a 15bit - * counter value (that reflects the number of times a worker has - * been inactivated) to avoid ABA effects (we need only as many - * version numbers as worker threads). Successors are held in - * field WorkQueue.nextWait. Queuing deals with several intrinsic - * races, mainly that a task-producing thread can miss seeing (and - * signalling) another thread that gave up looking for work but - * has not yet entered the wait queue. We solve this by requiring - * a full sweep of all workers (via repeated calls to method - * scan()) both before and after a newly waiting worker is added - * to the wait queue. During a rescan, the worker might release - * some other queued worker rather than itself, which has the same - * net effect. Because enqueued workers may actually be rescanning - * rather than waiting, we set and clear the "parker" field of - * WorkQueues to reduce unnecessary calls to unpark. (This - * requires a secondary recheck to avoid missed signals.) Note - * the unusual conventions about Thread.interrupts surrounding - * parking and other blocking: Because interrupts are used solely - * to alert threads to check termination, which is checked anyway - * upon blocking, we clear status (using Thread.interrupted) - * before any call to park, so that park does not immediately - * return due to status being set via some other unrelated call to - * interrupt in user code. - * - * Signalling. We create or wake up workers only when there - * appears to be at least one task they might be able to find and - * execute. However, many other threads may notice the same task - * and each signal to wake up a thread that might take it. So in - * general, pools will be over-signalled. When a submission is - * added or another worker adds a task to a queue that has fewer - * than two tasks, they signal waiting workers (or trigger - * creation of new ones if fewer than the given parallelism level - * -- signalWork), and may leave a hint to the unparked worker to - * help signal others upon wakeup). These primary signals are - * buttressed by others (see method helpSignal) whenever other - * threads scan for work or do not have a task to process. On - * most platforms, signalling (unpark) overhead time is noticeably - * long, and the time between signalling a thread and it actually - * making progress can be very noticeably long, so it is worth - * offloading these delays from critical paths as much as - * possible. - * - * Trimming workers. To release resources after periods of lack of - * use, a worker starting to wait when the pool is quiescent will - * time out and terminate if the pool has remained quiescent for a - * given period -- a short period if there are more threads than - * parallelism, longer as the number of threads decreases. This - * will slowly propagate, eventually terminating all workers after - * periods of non-use. - * - * Shutdown and Termination. A call to shutdownNow atomically sets - * a plock bit and then (non-atomically) sets each worker's - * qlock status, cancels all unprocessed tasks, and wakes up - * all waiting workers. Detecting whether termination should - * commence after a non-abrupt shutdown() call requires more work - * and bookkeeping. We need consensus about quiescence (i.e., that - * there is no more work). The active count provides a primary - * indication but non-abrupt shutdown still requires a rechecking - * scan for any workers that are inactive but not queued. - * - * Joining Tasks - * ============= - * - * Any of several actions may be taken when one worker is waiting - * to join a task stolen (or always held) by another. Because we - * are multiplexing many tasks on to a pool of workers, we can't - * just let them block (as in Thread.join). We also cannot just - * reassign the joiner's run-time stack with another and replace - * it later, which would be a form of "continuation", that even if - * possible is not necessarily a good idea since we sometimes need - * both an unblocked task and its continuation to progress. - * Instead we combine two tactics: - * - * Helping: Arranging for the joiner to execute some task that it - * would be running if the steal had not occurred. - * - * Compensating: Unless there are already enough live threads, - * method tryCompensate() may create or re-activate a spare - * thread to compensate for blocked joiners until they unblock. - * - * A third form (implemented in tryRemoveAndExec) amounts to - * helping a hypothetical compensator: If we can readily tell that - * a possible action of a compensator is to steal and execute the - * task being joined, the joining thread can do so directly, - * without the need for a compensation thread (although at the - * expense of larger run-time stacks, but the tradeoff is - * typically worthwhile). - * - * The ManagedBlocker extension API can't use helping so relies - * only on compensation in method awaitBlocker. - * - * The algorithm in tryHelpStealer entails a form of "linear" - * helping: Each worker records (in field currentSteal) the most - * recent task it stole from some other worker. Plus, it records - * (in field currentJoin) the task it is currently actively - * joining. Method tryHelpStealer uses these markers to try to - * find a worker to help (i.e., steal back a task from and execute - * it) that could hasten completion of the actively joined task. - * In essence, the joiner executes a task that would be on its own - * local deque had the to-be-joined task not been stolen. This may - * be seen as a conservative variant of the approach in Wagner & - * Calder "Leapfrogging: a portable technique for implementing - * efficient futures" SIGPLAN Notices, 1993 - * (http://portal.acm.org/citation.cfm?id=155354). It differs in - * that: (1) We only maintain dependency links across workers upon - * steals, rather than use per-task bookkeeping. This sometimes - * requires a linear scan of workQueues array to locate stealers, - * but often doesn't because stealers leave hints (that may become - * stale/wrong) of where to locate them. It is only a hint - * because a worker might have had multiple steals and the hint - * records only one of them (usually the most current). Hinting - * isolates cost to when it is needed, rather than adding to - * per-task overhead. (2) It is "shallow", ignoring nesting and - * potentially cyclic mutual steals. (3) It is intentionally - * racy: field currentJoin is updated only while actively joining, - * which means that we miss links in the chain during long-lived - * tasks, GC stalls etc (which is OK since blocking in such cases - * is usually a good idea). (4) We bound the number of attempts - * to find work (see MAX_HELP) and fall back to suspending the - * worker and if necessary replacing it with another. - * - * Helping actions for CountedCompleters are much simpler: Method - * helpComplete can take and execute any task with the same root - * as the task being waited on. However, this still entails some - * traversal of completer chains, so is less efficient than using - * CountedCompleters without explicit joins. - * - * It is impossible to keep exactly the target parallelism number - * of threads running at any given time. Determining the - * existence of conservatively safe helping targets, the - * availability of already-created spares, and the apparent need - * to create new spares are all racy, so we rely on multiple - * retries of each. Compensation in the apparent absence of - * helping opportunities is challenging to control on JVMs, where - * GC and other activities can stall progress of tasks that in - * turn stall out many other dependent tasks, without us being - * able to determine whether they will ever require compensation. - * Even though work-stealing otherwise encounters little - * degradation in the presence of more threads than cores, - * aggressively adding new threads in such cases entails risk of - * unwanted positive feedback control loops in which more threads - * cause more dependent stalls (as well as delayed progress of - * unblocked threads to the point that we know they are available) - * leading to more situations requiring more threads, and so - * on. This aspect of control can be seen as an (analytically - * intractable) game with an opponent that may choose the worst - * (for us) active thread to stall at any time. We take several - * precautions to bound losses (and thus bound gains), mainly in - * methods tryCompensate and awaitJoin. - * - * Common Pool - * =========== - * - * The static common Pool always exists after static - * initialization. Since it (or any other created pool) need - * never be used, we minimize initial construction overhead and - * footprint to the setup of about a dozen fields, with no nested - * allocation. Most bootstrapping occurs within method - * fullExternalPush during the first submission to the pool. - * - * When external threads submit to the common pool, they can - * perform some subtask processing (see externalHelpJoin and - * related methods). We do not need to record whether these - * submissions are to the common pool -- if not, externalHelpJoin - * returns quickly (at the most helping to signal some common pool - * workers). These submitters would otherwise be blocked waiting - * for completion, so the extra effort (with liberally sprinkled - * task status checks) in inapplicable cases amounts to an odd - * form of limited spin-wait before blocking in ForkJoinTask.join. - * - * Style notes - * =========== - * - * There is a lot of representation-level coupling among classes - * ForkJoinPool, ForkJoinWorkerThread, and ForkJoinTask. The - * fields of WorkQueue maintain data structures managed by - * ForkJoinPool, so are directly accessed. There is little point - * trying to reduce this, since any associated future changes in - * representations will need to be accompanied by algorithmic - * changes anyway. Several methods intrinsically sprawl because - * they must accumulate sets of consistent reads of volatiles held - * in local variables. Methods signalWork() and scan() are the - * main bottlenecks, so are especially heavily - * micro-optimized/mangled. There are lots of inline assignments - * (of form "while ((local = field) != 0)") which are usually the - * simplest way to ensure the required read orderings (which are - * sometimes critical). This leads to a "C"-like style of listing - * declarations of these locals at the heads of methods or blocks. - * There are several occurrences of the unusual "do {} while - * (!cas...)" which is the simplest way to force an update of a - * CAS'ed variable. There are also other coding oddities (including - * several unnecessary-looking hoisted null checks) that help - * some methods perform reasonably even when interpreted (not - * compiled). - * - * The order of declarations in this file is: - * (1) Static utility functions - * (2) Nested (static) classes - * (3) Static fields - * (4) Fields, along with constants used when unpacking some of them - * (5) Internal control methods - * (6) Callbacks and other support for ForkJoinTask methods - * (7) Exported methods - * (8) Static block initializing statics in minimally dependent order - */ - - // Static utilities - - /** - * If there is a security manager, makes sure caller has - * permission to modify threads. - */ - private static void checkPermission() { - SecurityManager security = System.getSecurityManager(); - if (security != null) - security.checkPermission(modifyThreadPermission); - } - - // Nested classes - - /** - * Factory for creating new {@link ForkJoinWorkerThread}s. - * A {@code ForkJoinWorkerThreadFactory} must be defined and used - * for {@code ForkJoinWorkerThread} subclasses that extend base - * functionality or initialize threads with different contexts. - */ - public static interface ForkJoinWorkerThreadFactory { - /** - * Returns a new worker thread operating in the given pool. - * - * @param pool the pool this thread works in - * @throws NullPointerException if the pool is null - */ - public ForkJoinWorkerThread newThread(ForkJoinPool pool); - } - - /** - * Default ForkJoinWorkerThreadFactory implementation; creates a - * new ForkJoinWorkerThread. - */ - static final class DefaultForkJoinWorkerThreadFactory - implements ForkJoinWorkerThreadFactory { - public final ForkJoinWorkerThread newThread(ForkJoinPool pool) { - return new ForkJoinWorkerThread(pool); - } - } - - /** - * Per-thread records for threads that submit to pools.

Reads and writes require volatile orderings - * but not CAS, because updates are only performed after slot - * CASes. - * - * Field "top" is the index (mod array.length) of the next queue - * slot to push to or pop from. It is written only by owner thread - * for push, or under lock for external/shared push, and accessed - * by other threads only after reading (volatile) base. Both top - * and base are allowed to wrap around on overflow, but (top - - * base) (or more commonly -(base - top) to force volatile read of - * base before top) still estimates size. The lock ("qlock") is - * forced to -1 on termination, causing all further lock attempts - * to fail.

Huge numbers of tasks and - * subtasks may be hosted by a small number of actual threads in a - * ForkJoinPool, at the price of some usage limitations. - * - * <p>A "main" {@code ForkJoinTask} begins execution when it is - * explicitly submitted to a {@link ForkJoinPool}, or, if not already - * engaged in a ForkJoin computation, commenced in the {@link - * ForkJoinPool#commonPool()} via {@link #fork}, {@link #invoke}, or - * related methods. Once started, it will usually in turn start other - * subtasks. As indicated by the name of this class, many programs - * using {@code ForkJoinTask} employ only methods {@link #fork} and - * {@link #join}, or derivatives such as {@link - * #invokeAll(ForkJoinTask...) invokeAll}. However, this class also - * provides a number of other methods that can come into play in - * advanced usages, as well as extension mechanics that allow support - * of new forms of fork/join processing. - * - * <p>A {@code ForkJoinTask} is a lightweight form of {@link Future}. - * The efficiency of {@code ForkJoinTask}s stems from a set of - * restrictions (that are only partially statically enforceable) - * reflecting their main use as computational tasks calculating pure - * functions or operating on purely isolated objects. The primary - * coordination mechanisms are {@link #fork}, that arranges - * asynchronous execution, and {@link #join}, that doesn't proceed - * until the task's result has been computed. Computations should - * ideally avoid {@code synchronized} methods or blocks, and should - * minimize other blocking synchronization apart from joining other - * tasks or using synchronizers such as Phasers that are advertised to - * cooperate with fork/join scheduling. Subdividable tasks should also - * not perform blocking I/O, and should ideally access variables that - * are completely independent of those accessed by other running - * tasks. These guidelines are loosely enforced by not permitting - * checked exceptions such as {@code IOExceptions} to be - * thrown. However, computations may still encounter unchecked - * exceptions, that are rethrown to callers attempting to join - * them. These exceptions may additionally include {@link - * RejectedExecutionException} stemming from internal resource - * exhaustion, such as failure to allocate internal task - * queues. Rethrown exceptions behave in the same way as regular - * exceptions, but, when possible, contain stack traces (as displayed - * for example using {@code ex.printStackTrace()}) of both the thread - * that initiated the computation as well as the thread actually - * encountering the exception; minimally only the latter. - * - * <p>It is possible to define and use ForkJoinTasks that may block, - * but doing do requires three further considerations: (1) Completion - * of few if any <em>other</em> tasks should be dependent on a task - * that blocks on external synchronization or I/O. Event-style async - * tasks that are never joined (for example, those subclassing {@link - * CountedCompleter}) often fall into this category. (2) To minimize - * resource impact, tasks should be small; ideally performing only the - * (possibly) blocking action. (3) Unless the {@link - * ForkJoinPool.ManagedBlocker} API is used, or the number of possibly - * blocked tasks is known to be less than the pool's {@link - * ForkJoinPool#getParallelism} level, the pool cannot guarantee that - * enough threads will be available to ensure progress or good - * performance. - * - * <p>The primary method for awaiting completion and extracting - * results of a task is {@link #join}, but there are several variants: - * The {@link Future#get} methods support interruptible and/or timed - * waits for completion and report results using {@code Future} - * conventions. Method {@link #invoke} is semantically - * equivalent to {@code fork(); join()} but always attempts to begin - * execution in the current thread. The "<em>quiet</em>" forms of - * these methods do not extract results or report exceptions. These - * may be useful when a set of tasks are being executed, and you need - * to delay processing of results or exceptions until all complete. - * Method {@code invokeAll} (available in multiple versions) - * performs the most common form of parallel invocation: forking a set - * of tasks and joining them all. - * - * <p>In the most typical usages, a fork-join pair act like a call - * (fork) and return (join) from a parallel recursive function. As is - * the case with other forms of recursive calls, returns (joins) - * should be performed innermost-first. For example, {@code a.fork(); - * b.fork(); b.join(); a.join();} is likely to be substantially more - * efficient than joining {@code a} before {@code b}. - * - * <p>The execution status of tasks may be queried at several levels - * of detail: {@link #isDone} is true if a task completed in any way - * (including the case where a task was cancelled without executing); - * {@link #isCompletedNormally} is true if a task completed without - * cancellation or encountering an exception; {@link #isCancelled} is - * true if the task was cancelled (in which case {@link #getException} - * returns a {@link java.util.concurrent.CancellationException}); and - * {@link #isCompletedAbnormally} is true if a task was either - * cancelled or encountered an exception, in which case {@link - * #getException} will return either the encountered exception or - * {@link java.util.concurrent.CancellationException}. - * - * <p>The ForkJoinTask class is not usually directly subclassed. - * Instead, you subclass one of the abstract classes that support a - * particular style of fork/join processing, typically {@link - * RecursiveAction} for most computations that do not return results, - * {@link RecursiveTask} for those that do, and {@link - * CountedCompleter} for those in which completed actions trigger - * other actions. Normally, a concrete ForkJoinTask subclass declares - * fields comprising its parameters, established in a constructor, and - * then defines a {@code compute} method that somehow uses the control - * methods supplied by this base class. - * - * <p>Method {@link #join} and its variants are appropriate for use - * only when completion dependencies are acyclic; that is, the - * parallel computation can be described as a directed acyclic graph - * (DAG). Otherwise, executions may encounter a form of deadlock as - * tasks cyclically wait for each other. However, this framework - * supports other methods and techniques (for example the use of - * {@link Phaser}, {@link #helpQuiesce}, and {@link #complete}) that - * may be of use in constructing custom subclasses for problems that - * are not statically structured as DAGs. To support such usages a - * ForkJoinTask may be atomically <em>tagged</em> with a {@code short} - * value using {@link #setForkJoinTaskTag} or {@link - * #compareAndSetForkJoinTaskTag} and checked using {@link - * #getForkJoinTaskTag}. The ForkJoinTask implementation does not use - * these {@code protected} methods or tags for any purpose, but they - * may be of use in the construction of specialized subclasses. For - * example, parallel graph traversals can use the supplied methods to - * avoid revisiting nodes/tasks that have already been processed. - * (Method names for tagging are bulky in part to encourage definition - * of methods that reflect their usage patterns.) - * - * <p>Most base support methods are {@code final}, to prevent - * overriding of implementations that are intrinsically tied to the - * underlying lightweight task scheduling framework. Developers - * creating new basic styles of fork/join processing should minimally - * implement {@code protected} methods {@link #exec}, {@link - * #setRawResult}, and {@link #getRawResult}, while also introducing - * an abstract computational method that can be implemented in its - * subclasses, possibly relying on other {@code protected} methods - * provided by this class. - * - * <p>ForkJoinTasks should perform relatively small amounts of - * computation. Large tasks should be split into smaller subtasks, - * usually via recursive decomposition. As a very rough rule of thumb, - * a task should perform more than 100 and less than 10000 basic - * computational steps, and should avoid indefinite looping. If tasks - * are too big, then parallelism cannot improve throughput. If too - * small, then memory and internal task maintenance overhead may - * overwhelm processing. - * - * <p>This class provides {@code adapt} methods for {@link Runnable} - * and {@link Callable}, that may be of use when mixing execution of - * {@code ForkJoinTasks} with other kinds of tasks. When all tasks are - * of this form, consider using a pool constructed in <em>asyncMode</em>. - * - * <p>ForkJoinTasks are {@code Serializable}, which enables them to be - * used in extensions such as remote execution frameworks. It is - * sensible to serialize tasks only before or after, but not during, - * execution.

When a thread tries to enqueue a data node, but - * encounters a request node, it instead "matches" and removes it; - * and vice versa for enqueuing requests. Blocking Dual Queues - * arrange that threads enqueuing unmatched requests block until - * other threads provide the match. Dual Synchronous Queues (see - * Scherer, Lea, & Scott - * http://www.cs.rochester.edu/u/scott/papers/2009_Scherer_CACM_SSQ.pdf) - * additionally arrange that threads enqueuing unmatched data also - * block. Dual Transfer Queues support all of these modes, as - * dictated by callers. - * - * A FIFO dual queue may be implemented using a variation of the - * Michael & Scott (M&S) lock-free queue algorithm - * (http://www.cs.rochester.edu/u/scott/papers/1996_PODC_queues.pdf). - * It maintains two pointer fields, "head", pointing to a - * (matched) node that in turn points to the first actual - * (unmatched) queue node (or null if empty); and "tail" that - * points to the last node on the queue (or again null if - * empty). For example, here is a possible queue with four data - * elements: - * - * head tail - * | | - * v v - * M -> U -> U -> U -> U - * - * The M&S queue algorithm is known to be prone to scalability and - * overhead limitations when maintaining (via CAS) these head and - * tail pointers. This has led to the development of - * contention-reducing variants such as elimination arrays (see - * Moir et al http://portal.acm.org/citation.cfm?id=1074013) and - * optimistic back pointers (see Ladan-Mozes & Shavit - * http://people.csail.mit.edu/edya/publications/OptimisticFIFOQueue-journal.pdf). - * However, the nature of dual queues enables a simpler tactic for - * improving M&S-style implementations when dual-ness is needed. - * - * In a dual queue, each node must atomically maintain its match - * status. While there are other possible variants, we implement - * this here as: for a data-mode node, matching entails CASing an - * "item" field from a non-null data value to null upon match, and - * vice-versa for request nodes, CASing from null to a data - * value. (Note that the linearization properties of this style of - * queue are easy to verify -- elements are made available by - * linking, and unavailable by matching.) Compared to plain M&S - * queues, this property of dual queues requires one additional - * successful atomic operation per enq/deq pair. But it also - * enables lower cost variants of queue maintenance mechanics. (A - * variation of this idea applies even for non-dual queues that - * support deletion of interior elements, such as - * j.u.c.ConcurrentLinkedQueue.) - * - * Once a node is matched, its match status can never again - * change. We may thus arrange that the linked list of them - * contain a prefix of zero or more matched nodes, followed by a - * suffix of zero or more unmatched nodes. (Note that we allow - * both the prefix and suffix to be zero length, which in turn - * means that we do not use a dummy header.) If we were not - * concerned with either time or space efficiency, we could - * correctly perform enqueue and dequeue operations by traversing - * from a pointer to the initial node; CASing the item of the - * first unmatched node on match and CASing the next field of the - * trailing node on appends. (Plus some special-casing when - * initially empty). While this would be a terrible idea in - * itself, it does have the benefit of not requiring ANY atomic - * updates on head/tail fields. - * - * We introduce here an approach that lies between the extremes of - * never versus always updating queue (head and tail) pointers. - * This offers a tradeoff between sometimes requiring extra - * traversal steps to locate the first and/or last unmatched - * nodes, versus the reduced overhead and contention of fewer - * updates to queue pointers. For example, a possible snapshot of - * a queue is: - * - * head tail - * | | - * v v - * M -> M -> U -> U -> U -> U - * - * The best value for this "slack" (the targeted maximum distance - * between the value of "head" and the first unmatched node, and - * similarly for "tail") is an empirical matter. We have found - * that using very small constants in the range of 1-3 work best - * over a range of platforms. Larger values introduce increasing - * costs of cache misses and risks of long traversal chains, while - * smaller values increase CAS contention and overhead. - * - * Dual queues with slack differ from plain M&S dual queues by - * virtue of only sometimes updating head or tail pointers when - * matching, appending, or even traversing nodes; in order to - * maintain a targeted slack. The idea of "sometimes" may be - * operationalized in several ways. The simplest is to use a - * per-operation counter incremented on each traversal step, and - * to try (via CAS) to update the associated queue pointer - * whenever the count exceeds a threshold. Another, that requires - * more overhead, is to use random number generators to update - * with a given probability per traversal step. - * - * In any strategy along these lines, because CASes updating - * fields may fail, the actual slack may exceed targeted - * slack. However, they may be retried at any time to maintain - * targets. Even when using very small slack values, this - * approach works well for dual queues because it allows all - * operations up to the point of matching or appending an item - * (hence potentially allowing progress by another thread) to be - * read-only, thus not introducing any further contention. As - * described below, we implement this by performing slack - * maintenance retries only after these points. - * - * As an accompaniment to such techniques, traversal overhead can - * be further reduced without increasing contention of head - * pointer updates: Threads may sometimes shortcut the "next" link - * path from the current "head" node to be closer to the currently - * known first unmatched node, and similarly for tail. Again, this - * may be triggered with using thresholds or randomization. - * - * These ideas must be further extended to avoid unbounded amounts - * of costly-to-reclaim garbage caused by the sequential "next" - * links of nodes starting at old forgotten head nodes: As first - * described in detail by Boehm - * (http://portal.acm.org/citation.cfm?doid=503272.503282) if a GC - * delays noticing that any arbitrarily old node has become - * garbage, all newer dead nodes will also be unreclaimed. - * (Similar issues arise in non-GC environments.) To cope with - * this in our implementation, upon CASing to advance the head - * pointer, we set the "next" link of the previous head to point - * only to itself; thus limiting the length of connected dead lists. - * (We also take similar care to wipe out possibly garbage - * retaining values held in other Node fields.) However, doing so - * adds some further complexity to traversal: If any "next" - * pointer links to itself, it indicates that the current thread - * has lagged behind a head-update, and so the traversal must - * continue from the "head". Traversals trying to find the - * current tail starting from "tail" may also encounter - * self-links, in which case they also continue at "head". - * - * It is tempting in slack-based scheme to not even use CAS for - * updates (similarly to Ladan-Mozes & Shavit). However, this - * cannot be done for head updates under the above link-forgetting - * mechanics because an update may leave head at a detached node. - * And while direct writes are possible for tail updates, they - * increase the risk of long retraversals, and hence long garbage - * chains, which can be much more costly than is worthwhile - * considering that the cost difference of performing a CAS vs - * write is smaller when they are not triggered on each operation - * (especially considering that writes and CASes equally require - * additional GC bookkeeping ("write barriers") that are sometimes - * more costly than the writes themselves because of contention). - * - * *** Overview of implementation *** - * - * We use a threshold-based approach to updates, with a slack - * threshold of two -- that is, we update head/tail when the - * current pointer appears to be two or more steps away from the - * first/last node. The slack value is hard-wired: a path greater - * than one is naturally implemented by checking equality of - * traversal pointers except when the list has only one element, - * in which case we keep slack threshold at one. Avoiding tracking - * explicit counts across method calls slightly simplifies an - * already-messy implementation. Using randomization would - * probably work better if there were a low-quality dirt-cheap - * per-thread one available, but even ThreadLocalRandom is too - * heavy for these purposes. - * - * With such a small slack threshold value, it is not worthwhile - * to augment this with path short-circuiting (i.e., unsplicing - * interior nodes) except in the case of cancellation/removal (see - * below). - * - * We allow both the head and tail fields to be null before any - * nodes are enqueued; initializing upon first append. This - * simplifies some other logic, as well as providing more - * efficient explicit control paths instead of letting JVMs insert - * implicit NullPointerExceptions when they are null. While not - * currently fully implemented, we also leave open the possibility - * of re-nulling these fields when empty (which is complicated to - * arrange, for little benefit.) - * - * All enqueue/dequeue operations are handled by the single method - * "xfer" with parameters indicating whether to act as some form - * of offer, put, poll, take, or transfer (each possibly with - * timeout). The relative complexity of using one monolithic - * method outweighs the code bulk and maintenance problems of - * using separate methods for each case. - * - * Operation consists of up to three phases. The first is - * implemented within method xfer, the second in tryAppend, and - * the third in method awaitMatch. - * - * 1. Try to match an existing node - * - * Starting at head, skip already-matched nodes until finding - * an unmatched node of opposite mode, if one exists, in which - * case matching it and returning, also if necessary updating - * head to one past the matched node (or the node itself if the - * list has no other unmatched nodes). If the CAS misses, then - * a loop retries advancing head by two steps until either - * success or the slack is at most two. By requiring that each - * attempt advances head by two (if applicable), we ensure that - * the slack does not grow without bound. Traversals also check - * if the initial head is now off-list, in which case they - * start at the new head. - * - * If no candidates are found and the call was untimed - * poll/offer, (argument "how" is NOW) return. - * - * 2. Try to append a new node (method tryAppend) - * - * Starting at current tail pointer, find the actual last node - * and try to append a new node (or if head was null, establish - * the first node). Nodes can be appended only if their - * predecessors are either already matched or are of the same - * mode. If we detect otherwise, then a new node with opposite - * mode must have been appended during traversal, so we must - * restart at phase 1. The traversal and update steps are - * otherwise similar to phase 1: Retrying upon CAS misses and - * checking for staleness. In particular, if a self-link is - * encountered, then we can safely jump to a node on the list - * by continuing the traversal at current head. - * - * On successful append, if the call was ASYNC, return. - * - * 3. Await match or cancellation (method awaitMatch) - * - * Wait for another thread to match node; instead cancelling if - * the current thread was interrupted or the wait timed out. On - * multiprocessors, we use front-of-queue spinning: If a node - * appears to be the first unmatched node in the queue, it - * spins a bit before blocking. In either case, before blocking - * it tries to unsplice any nodes between the current "head" - * and the first unmatched node. - * - * Front-of-queue spinning vastly improves performance of - * heavily contended queues. And so long as it is relatively - * brief and "quiet", spinning does not much impact performance - * of less-contended queues. During spins threads check their - * interrupt status and generate a thread-local random number - * to decide to occasionally perform a Thread.yield. While - * yield has underdefined specs, we assume that it might help, - * and will not hurt, in limiting impact of spinning on busy - * systems. We also use smaller (1/2) spins for nodes that are - * not known to be front but whose predecessors have not - * blocked -- these "chained" spins avoid artifacts of - * front-of-queue rules which otherwise lead to alternating - * nodes spinning vs blocking. Further, front threads that - * represent phase changes (from data to request node or vice - * versa) compared to their predecessors receive additional - * chained spins, reflecting longer paths typically required to - * unblock threads during phase changes. - * - * - * ** Unlinking removed interior nodes ** - * - * In addition to minimizing garbage retention via self-linking - * described above, we also unlink removed interior nodes. These - * may arise due to timed out or interrupted waits, or calls to - * remove(x) or Iterator.remove. Normally, given a node that was - * at one time known to be the predecessor of some node s that is - * to be removed, we can unsplice s by CASing the next field of - * its predecessor if it still points to s (otherwise s must - * already have been removed or is now offlist). But there are two - * situations in which we cannot guarantee to make node s - * unreachable in this way: (1) If s is the trailing node of list - * (i.e., with null next), then it is pinned as the target node - * for appends, so can only be removed later after other nodes are - * appended. (2) We cannot necessarily unlink s given a - * predecessor node that is matched (including the case of being - * cancelled): the predecessor may already be unspliced, in which - * case some previous reachable node may still point to s. - * (For further explanation see Herlihy & Shavit "The Art of - * Multiprocessor Programming" chapter 9). Although, in both - * cases, we can rule out the need for further action if either s - * or its predecessor are (or can be made to be) at, or fall off - * from, the head of list. - * - * Without taking these into account, it would be possible for an - * unbounded number of supposedly removed nodes to remain - * reachable. Situations leading to such buildup are uncommon but - * can occur in practice; for example when a series of short timed - * calls to poll repeatedly time out but never otherwise fall off - * the list because of an untimed call to take at the front of the - * queue. - * - * When these cases arise, rather than always retraversing the - * entire list to find an actual predecessor to unlink (which - * won't help for case (1) anyway), we record a conservative - * estimate of possible unsplice failures (in "sweepVotes"). - * We trigger a full sweep when the estimate exceeds a threshold - * ("SWEEP_THRESHOLD") indicating the maximum number of estimated - * removal failures to tolerate before sweeping through, unlinking - * cancelled nodes that were not unlinked upon initial removal. - * We perform sweeps by the thread hitting threshold (rather than - * background threads or by spreading work to other threads) - * because in the main contexts in which removal occurs, the - * caller is already timed-out, cancelled, or performing a - * potentially O(n) operation (e.g. remove(x)), none of which are - * time-critical enough to warrant the overhead that alternatives - * would impose on other threads. - * - * Because the sweepVotes estimate is conservative, and because - * nodes become unlinked "naturally" as they fall off the head of - * the queue, and because we allow votes to accumulate even while - * sweeps are in progress, there are typically significantly fewer - * such nodes than estimated. Choice of a threshold value - * balances the likelihood of wasted effort and contention, versus - * providing a worst-case bound on retention of interior nodes in - * quiescent queues. The value defined below was chosen - * empirically to balance these under various timeout scenarios. - * - * Note that we cannot self-link unlinked interior nodes during - * sweeps. However, the associated garbage chains terminate when - * some successor ultimately falls off the head of the list and is - * self-linked. - */ - - /** True if on multiprocessor */ - private static final boolean MP = - Runtime.getRuntime().availableProcessors() > 1; - - /** - * The number of times to spin (with randomly interspersed calls - * to Thread.yield) on multiprocessor before blocking when a node - * is apparently the first waiter in the queue.

As a more - * concrete simple example, the following task increments each element - * of an array: - * <pre> {@code - * class IncrementTask extends RecursiveAction { - * final long[] array; final int lo, hi; - * IncrementTask(long[] array, int lo, int hi) { - * this.array = array; this.lo = lo; this.hi = hi; - * } - * protected void compute() { - * if (hi - lo < THRESHOLD) { - * for (int i = lo; i < hi; ++i) - * array[i]++; - * } - * else { - * int mid = (lo + hi) >>> 1; - * invokeAll(new IncrementTask(array, lo, mid), - * new IncrementTask(array, mid, hi)); - * } - * } - * }}</pre> - * - * <p>The following example illustrates some refinements and idioms - * that may lead to better performance: RecursiveActions need not be - * fully recursive, so long as they maintain the basic - * divide-and-conquer approach.
