shared memory parallel programmingall-uses testingParallelism has become a way of life for many scientific programmers. A significant challenge in bringing the power of parallel machines to these programmers is providing them with a suite of software tools similar to the tools that sequential ...
Standard for shared memory programming for scientific applications. Has specific support for scientific application needs (unlike Pthreads). Rapidly gaining acceptance among vendors and application writers. See for more info. OpenMP API Overview API is a set of compiler directives inserted in the source...

Shared-Memory Programming with OpenMP CHAPTER 5 Like Pthreads, OpenMP is an API for shared-memory parallel programming. The "MP" in OpenMP stands for "multiprocessing," a term that is synonymous with shared-memory parallel computing. Thus, OpenMP is designed for systems in which each thread or...

Book2011, An Introduction to Parallel Programming Peter S. Pacheco Explore book Shared-memory systems The most widely available shared-memory systems use one or more multicore processors. As we discussed in Chapter 1, a multicore processor has multiple CPUs or cores on a single chip. Typically,...
1) shared-memory parallel programming 共享存储并行编程1. To overcome the efficiency bottleneck,a coarse-grained parallel multi-target tracking implementation based on the OpenMP-specified shared-memory parallel programming model was explored. 为克服性能瓶颈,探索了一种基于OpenMP共享存储并行编程模型的粗...
