引入了线程并行，OpenMP并行框架。讨论的主题包括：使用线程来利用多个处理器内核，线程和数据并行，协调使用OpenMP线程的创建和团队他们处理循环和树木的任务。OpenMP的讨论提到控制线程的数量，控制变量条款和范围的共享，循环调度模式，使用互斥锁来保护竞争的条件，并与线程私有变量减少并行可扩展的方法。讲座部分的结论与讨论的一般方法来实现在计算应用中的并行的机会。动手部分演示了使用OpenMP并行串行计算和论证了循环变量共享，在一个应用实例进行数值积分的互斥和并行还原。-Session 4 introduces thread parallelism and the parallel fr a mework OpenMP. Discussed topics include: using threads to utilize multiple processor cores, coordination of thread and data parallelism, using OpenMP to create threads and team them up to process loops and trees of tasks. OpenMP discussion mentions controlling the number of threads, controlling variable sharing with clauses and scoping, loop scheduling modes, using mutexes to protect race conditions, and scalable approach to parallel reduction with thread-private variables. The lecture part concludes with a discussion of the general approach to realizing opportunities for parallelism in computing applications. The hands-on part demonstrates using OpenMP to parallelize serial computation and demonstrates for-loops, variable sharing, mutexes and parallel reduction on an example application performing numerical integration.
