摘要
文章介绍了OpenMP的并行执行原理和语言规范,讨论了OpenMP的循环并行化、迭代相关、数据共享、任务调度等问题。接着研究了高斯-约当消元法固有的并行性,提出并行高斯-约当消元法,并基于多处理器平台HPZ620进行了测试。实验结果表明,理论分析与实验结果是一致的。
This paper discusses the principles and the language specification of the parallel implementations of OpenMP, focusing on the OpenMP parallel loop, iterative correlation, data sharing, task scheduling and other issues.By analyzing the inherent parallelism of Gauss-Jordan elimination method, the parallel Gauss-Jordan elimination algorithms are introduced. The test on the basis of the multiprocessor platform HP Z620 shows that the theory andexperiments are concordant.
