Modern processors have multiple cores on a chip to overcome power consumption and heat dissipation issues. As more and more compute cores become available on a single node, it is expected that node-local communication will play an increasingly greater role in overall performance of parallel applications such as MPI applications. It is therefore crucial to optimize intra-node communication paths utilized by MPI libraries. In this paper, we propose a novel design of a kernel extension, called… CONTINUE READING
