This paper investigates the communication characteristics of the Message Passing Interface (MPI) implementation of the NAS parallel benchmarks and study the effectiveness of compiled communication for MPI programs. Compiled communication is a technique that utilizes the compiler knowledge of both the application communication requirement and the underlying network architecture to significantly optimize the performance of communications whose information can be determined at compile time (Static communications).
