This paper presents dynamic memory usage of Open MPI by DMATP-MPI dynamic memory usage analysis tool. The DMATP-MPI is developed to reduce memory usage of MPI communication library. The evaluation results show that the memory usage of MPI Init function increases by increasing number of processes, and must be reduced for post peta-scale systems.
