Abstract

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.
