摘要：

The Message Passing Interface (MPI) has become the standard in achieving effective results when using the message passing paradigm of parallelization. Codes written using MPI are extremely portable, and are applicable to both clusters and massively parallel computing platforms. Since MPI uses the single program, multiple data (SPMD) approach to parallelism, good performance requires careful tuning of the serial code, as well as careful data and control flow analysis to limit communication. We discuss optimization strategies used and their degree of success to increase performance of an MPI-based unstructured finite element simulations code written in Fortran 90. We discuss performance results based on implementations using several modern massively parallel computing platforms including the SGI Origin 3800, IBM Nighthawk 2 SMP, and Cray T3E-1200.
