代表的なメッセージ通信APIであるMPIには、基本仕様のMPI-1と拡張仕様のMPI-2がある。MPI-1向けのベンチマークは幾つか提案されているが、MPI-2向けのベンチマークは少なく計測項目も限られている。そこでMPI-2(特に並列I/O(MPI-I/O)と片側通信(RMA))のベンチマーク(MBL2: MPI Benchmark program Library for MPI-2)の構築を試みた。

MPI in one of major message communication interfaces for application programs. The MPI consists of an MPI-1 as a basic specification, and an MPI-2 as extensions. Some benchmark programs for MPI-1 capabilities are proposed. However benchmark programs for MPI-2 are a little and their measurements are limited. We have developed an MPI benchmark program library for MPI-2 (MBL2) which measures the performance of MPI-I/O and RMA.
