Abstract: This paper discusses performance model of parallel communication for message passing interface(MPI), tests some performance criteria under point to point and group communication, and concluds statiscal model of these performance criteria, which can be taken as the basis for evaluating fesibility and expansibility of engineering problem's parallel calculation.
