Abstract

We present our MPI-BIP implementation, designed for Myrinet networks, and based on MPICH. By using our "Basic Interface for Parallelism: BIP" software layer, we obtain in this implementation of the MPI protocols results close to the peak hardware performance of the high speed Myrinet network. We present the protocols we used to implement the MPI semantics, and the overall design of the implementation. We, then, present benchmarks and application results to show that this design leads to parallel multicomputer-like throughput and latency on a cluster of PC workstations.
