1.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。

2.As you can see, pthread_mutex_init accepts a pointer to an already-allocated region of memory to initiapze 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。

3.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。

4.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。

5.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。

6.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

7.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。

8.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）。

9.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。

10.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。
