(English Abstract)
The memory-mapping-based mechanism designed for intra-node communication of MPI programming model can perform intra-node communication with single data copy. There has been an increase in the ratio of intra-node communication in MPI programming model due to the development of the manycore system. It is expected that improvement in MPI intra-node communication performance in the manycore system can be achieved by understanding the characteristics and mitigating overhead of communication primitives for memory-mapping-based mechanism. In this paper, we compare latency and receiver side overhead of point-to-point communication and broadcast collective communication using LiMIC, CMA, and XPMEM which communication primitive for memory-mapping-based mechanism. Based on the results it is clear that XPMEM exhibits up to 7.4 times higher latency compared to LiMIC and CMA in case of point-to-point communication and XPMEM exhibits up to 3.8 times higher latency compared to LiMIC and CMA in case of broadcast collective communication.
