| 摘 要： | 通过对MPICH作业提交方式的研究，进而优化作业的提交过程，提出了一种SBM方法，即一种新的作业提交方式，减少了通信的时间，得到更高的通信性能，实现了对MPICH作业提交方式的改进。设计并实现了基于SBM方法的MPICH系统，并与采用传统方法的系统进行了性能对比，证明了在大型并行计算中，基于SBM作业提交方式可以得到更好的通信性能。

| Abstract: | The purpose of this paper is to describe how to optimize submitting jobs in MPICH through the research on the original submitting job method and thus decrease the communication time and get better communication performance. This paper discusses a new method which is called SBM method for submitting job in MPICH to decrease the startup time and thus to improve communication performance. Indeed the communication time based on the SBM method for job submission is proved experimentally to be much faster than the communication time using a comparable algorithm based on an original method, especially when the number of nodes participated becomes very large. |
