SUN5500小型机MPI编程与蕴式并行计算的实现方法

MPI Programming and Implied Parallel on SUN5500

基于SUN5500小型计算机并行开发环境,给出了消息传递模型和蕴式并行模型的实现方法,通过实例分析了SUN MPI实际编程,并对选取不同模型及不同参数时的运算时间进行了比较,结果表明,在SUN5500计算机上MPI模型和蕴式并行模型均能较大地提高运算速度,而且MPI在灵活性和并行程度方面更优.

Based on SUN5500's parallel development environment, this paper provides implementing methods for message passing model and implied parallel model. An actual MPI application programme is analysed and the computing-time while selecting different models and different parameters is compared. The results show that both models can improve computing speed greatly on SUN5500,but MPI model is better in flexibility and parallel programming.
