Overlapping computation with communication is a key technique to conceal the effect of communication latency on the performance of parallel applications. MPI is a widely used message passing standard for high performance computing. One of the most important factors in achieving a good level of overlap is the MPI ability to make progress on outstanding communication operations. In this paper, we address some of the communication progress shortcomings in the current polling and RDMA Read based… CONTINUE READING
