execution_queue_start函数有四个参数,id用于定位到这个queue,ExecutionQueueId类型本质上是uint_64,也就是execution_queue_start执行后id保存了队列对应的id,在执行任务的时候作为参数可以直接定位到需要的队列,第二个队列的option,里面只有一个任务执行用的bthread的属性,第三个参数则是核心的执
int execution_queue_start( ExecutionQueueId<T>* id, const ExecutionQueueOptions* options, int (*execute)(void* meta, TaskIterator<T>& iter), void* meta); execution_queue_start是创建一个队列,并返回一个id。execute是我们需要注册的消费者如何消费的函数指针,其中的iter是任务的迭代器,在消费者的回...
execution_queue_execute 执行任务接口:id为execution_queue_start接口生成的队列Id;task为我们定义的任务信息对象;options中包含high_priority(是否高优)和 in_place_if_possible(是否在本bthread中执行)2个属性,注意与execution_queue_start中的options区分开。 template <typename T> inline int execution_queue_execut...
3.2 示例:使用Future实现页面的渲染器 3.3 CompletionService: Executor与BlockingQueue 计算完成后FutureTask会调用done方法,而CompletionService集成了FutureTask,对于计算完毕的结果直接放在自己维护的BlockingQueue里面,这样上层调用者就可以一个个take或者poll出来。 3.3 示例:使用CompletionService提高渲染性能 代码语言:javascript...
The dispatch adjust circuit may also receive a queue empty signal from the queues to detect when they are empty to send a start signal to the issuer.Wen-Tzer T. ChenDiane G. FlemmingSandy K. KaoWilliam A. MaronMysore S. Srinivas
instead of java.util.concurrent.Semaphore since we don't need blocking and need a custom implementation to get the dynamic permit count and since * AtomicInteger achieves the same behavior and performance without the more complex implementation of the actual Semaphore class using AbstractQueue...
Interactions between the event queue and a process (a), actions that repeat during every simulation cycle (b). Event-driven simulation works in cycles where three stages alternate: 1. Advance simulation time to the next transaction in the event queue thereby making it the current one.26 2. ...
最后一个参数表示FixedThreadPool使用了无界队列LinkedBlockingQueue作为线程池的做工队列,由于是无界的,当线程池的线程数达到corePoolSize后,新任务将在无界队列中等待,因此线程池的线程数量不会超过corePoolSize,同时maxiumPoolSize也就变成了一个无效的参数,并且运行中的线程池并不会拒绝任务。
Simultaneous execution of multiple kernels. Early CUDA systems allow only one kernel to execute on eachGPUdevice at any point in time. Multiple kernel functions can be submitted for execution. However, they are buffered in a queue that releases the next kernel after the current one completes exec...
()method. That second statement execution operation is added to the queue behind the first statement. As soon as the first statement finishes executing, the runtime moves to the next operation in the queue. The processing of subsequent operations in the queue happens in the background, even ...
