Abstract

In this paper, hardware support for MPI on the DIMMnet-2 network interface plugged into a DDR DIMM slot is presented. This hardware support realize effective eager protocol and effective derived datatype communication of MPI. As a preliminary evaluation, the evaluation results on the real prototype concerning the bandwidth of elements constituting MPI are shown. IPUSH, which is remote indirect writing, showed almost the same performance as RDMA, which is remote direct writing. IPUSH can reduce memory space required for a receiver buffer sharply The memory space reduction effect of IPUSH on a system with more nodes is higher. Compared with a method that starts the burst vector loading many times, VLS, which performs a regular-interval vector loading, sharply accelerated access to the data arranged at regular intervals. The above-mentioned results indicate that the improvement in the speed of MPI by the proposed method is promising.
