MPI is 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 program for MPI-1 had been proposed already. 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 detail performance of MPI-I/O and RMA functions of MPI-2. In this report, we describe the MBL2 and performance data of MPI-2 on VPP5000, which we measured using MBL2.
