pthread英文翻译_含义_读音_pthread例句

I further tested this simple Pthread code on the PPE to see how it scales with an increasing number of threads.

我在PPE上进一步测试了这个简单的Pthread代码，以此了解随着线程数量的增加它的性能变化情况。

As you can see, pthread_mutex_init accepts a pointer to an already-allocated region of memory to initialize as a mutex.

正如所示，pthread_mutex_init接受一个指针作为参数以初始化为互斥对象，该指针指向一块已分配好的内存区。

In other words, the system allocates at least 10MB of private storage for each pthread.

换言之，系统为每个pthread分配至少10MB的专用存储。

This sounds a bit confusing, but the pthread example below will clarify how condition variables work.

这听起来有点难以理解，下面的pthread例子会说明条件变量是怎么工作的。

Thus, PTHREAD_PROCESS_SHARED and interprocess POSIX synchronization primitives can be implemented and are now available.

这样，PTHREAD_PROCESS_SHARED和进程间POSIX同步原语可以被实现，而且现在可用。

pthread -qthreaded or _r invocation mode Creates programs running in a multithreaded environment.

pthread-qthreaded或_r调用模式创建在多线程环境中运行的程序

In Linux, pthread_cond_signal wakes up a thread waiting on a conditional variable.

在Linux中，pthread_cond_signal会唤醒等待某个条件变更的某个线程。

Futex (fast user space mutex) is done by the kernel on the thread ID upon pthread_join (for more on futex, please see Resources).

当pthread_join发生时由内核根据线程ID来完成Futex（fastuserspacemutex）。（要了解futex的更多信息，请参阅参考资料）。

POSIX provides locking and synchronization support through the pthread_mutex data type.

POSIX通过pthread_mutex数据类型提供锁定和同步支持。

In Linux, the pthread_cancel method terminates execution of the thread identified by the specified threadId.

在Linux中，pthread_cancel可以终止由具体的threadId所标识的线程的执行。

Note that you've invoked pthread_cond_broadcast after releasing the mutex.

注意，在释放互斥锁之后调用pthread_cond_broadcast。

If the list were originally empty, you call pthread_cond_broadcast to post push data into the list.

如果列表原来是空的，就调用pthread_cond_broadcast以宣告列表中已经添加了数据。

In libspe2, the operation is synchronous, so if you want to run a thread in the background, you have to make your own pthread calls.

在libspe2中，这个操作变成同步的了，因此您可能会希望在后台运行一个线程，并发出自己的pthread调用。

A POSIX API for creating a pthread_mutex lets the mutex implement the priority -inheritance protocol.

用于创建pthread_mutex的POSIXAPI使用互斥锁来实现优先级继承协议。

If you need to block the calling thread for a specific time, then use the pthread_cond_timewait to block the thread.

如果您需要在指定的一段时间内阻塞发出调用的线程，那么请使用pthread_cond_timewait来阻塞它。

pthread_mutexes can be created with different locking policies.

pthread_mutex可以使用不同的锁定策略创建。

pthread_rwlock_rdlock may fail if the maximum number of read locks (implementation defined) for the lock has been exceeded.

如果超过了最大读锁数量（由实现定义），pthread_rwlock_rdlock可能会失败。

This careful Pthread scheduling leads to much more deterministic and repeatable test runs.

这种仔细的Pthread调度方法使测试运行的结果更加准确，可重复性更高。

Table 1 above displays the pthread condition variable for synchronization between threads.

前面的表1给出了用于线程间同步的pthread条件变量。

You can further optimize this situation by using pthread_mutex_timedlock API, if your system supports it (see Resources).

如果系统支持的话，可以使用pthread_mutex_timedlockAPI进一步优化这个场景（见参考资料）。

Instead of providing an abstraction of logical SPUs, this interface is thread-oriented and behaves in a similar way to the pthread library.

这个接口并不是提供一个逻辑SPU的抽象，而是面向线程的，它的工作方式与pthread库类似。

The linker complained of some missing pthreads-related exports.

链接器抱怨缺少与pthread相关的输出。

Otherwise, it can be created statically when it is declared by a pthread_mutex_t variable.

或者，当通过pthread_mutex_t变量声明它的时候，可以静态地创建它。

Meanwhile, you can use pthread_xxxx calls at any time after the thread has been created.

同时，您在创建线程之后的任意时候都可以使用pthread_xxxx。

Linux pthread mutexes are supported by fast user-space mutexes, known as futexes.

快速用户空间互斥（也被称为futexes）支持Linuxpthread互斥锁。

Immediately after unlocking the mutex, thread 2 calls the function pthread_cond_broadcast(&mycond).

在对互斥对象解锁之后，2号线程会立即调用函数pthread_cond_broadcast（&mycond）。

With this background, let's look at the function pthread_cond_timedwait, which you use for the second check.

有了这些背景知识，我们来看看pthread_cond_timedwait函数，这个函数用于进行第二个检查。

While still holding the mutex lock, our thread will call pthread_cond_wait(&mycond, &mymutex).

锁定互斥对象时，线程将调用pthread_cond_wait（&mycond，&mymutex）。

Take care to invoke pthread_rwlock_unlock n times if there are n concurrent read locks for the lock.

如果有n个并发的读锁，一定要调用pthread_rwlock_unlockn次。

The POSIX lock type is a pthread_mutex.
