摘　　要：针对共享存储式(SMP)并行处理机的特点,以PowerChallengeXL并行处理机为例,对并行编程所涉及到的影响并行性能的因素以及程序并行的方式进行了探讨.结果表明,在编程的过程中,通过减少并行开销、解决负载不均衡以及选择合理的并行粒度,可提高并行程序的加速比,改善机器的运行效能.The factors that influenced parallel programming and the way of program parallelization were discussed with parallel processor of Power Challenge XL according to the characteristic of Symmetric Multiprocessor of the parallel processor of storing type. During the process of programming,the program speedup increased End operation efficiency of computer improved reducing parallelization overhead, solving the problem of unbalanced load and making rational choice of grained parallelism.
