运行时参数,以简化 CWorker和 CWorkerThread对象的结构。使用值类型 结构(而不是引用类型类)能够确保这些运行时参数维护的是数值(而不 是引用)。 IWebMessage 接口 CWorkerThread 的实现之一是一个调用组件方法的类。这个名为 CWorkerThreadAssembly 的类使用 IWebMessage接口来定义服务和组件之 间的约定。 与当前版...

Use theMQCreateSessionfunction to create a session and to specify its acknowledge mode and its receive mode. If the session will be used only for producing messages, use the receive modeMQ_SESSION_SYNC_RECEIVEto avoid creating a thread for asynchronous message delivery. ...

线程并行(Thread-level parallelism, TLP):通过创建多个线程,将任务分配给这些线程并行处理。线程之间可以共享内存资源,但需要注意同步和互斥以避免数据竞争和死锁等问题。 任务并行(Task-level parallelism):将问题分解为可以独立处理的任务,这些任务可以在不同的处理器或计算资源上并行执行。任务并行可以与线程并行相结合...
