RSS订阅原创 归来，算24
好长时间没有来过，今天上来坐坐。 有点小伤心，以前写的东西都不在了，虽然以前写的东西不多，但也是我的成长记忆啊！甚是可惜。 系统提示修改邮箱的时候，无意间看到了2001年注册时使用的邮箱，不禁想起了第一次注册时坐在的城市广州，起他的很多事情也涌入心头，莫名有些感概。 既然来了，总要留下点东西吧。最近在家陪孩子算24，索性写了一个程序，对PYTHON语法不太熟悉，程序运行结果如下，如果大家感兴趣...

POSIX Threads Programming
In shared memory multiprocessor architectures, such as SMPs, threads can be used to implement parallelism. Historically, hardware vendors have implemented their own proprietary versions of threads, making portability a concern for software developers. For UNIX systems, a standardized C language threads programming interface has been specified by the IEEE POSIX 1003.1c standard. Implementations that adhere to this standard are referred to as POSIX threads, or Pthreads. <br><br>The tutorial begins with an introduction to concepts, motivations, and design considerations for using Pthreads. Each of the three major classes of routines in the Pthreads API are then covered: Thread Management, Mutex Variables, and Condition Variables. Example codes are used throughout to demonstrate how to use most of the Pthreads routines needed by a new Pthreads programmer. The tutorial concludes with a discussion and examples of how to develop hybrid MPI/Pthreads programs in an IBM SMP environment. A lab exercise, with numerous example codes (C Language) is also included<br>
