– Communication overhead is one of the dominant factors that affect performance in high-performance computing systems. To reduce the negative impact of communication, programmers...
Collective operations and non-blocking point-to-point operations are two important parts of MPI that each provide important performance and programmability benefits. Although non...
Effective overlap of computation and communication is a well understood technique for latency hiding and can yield significant performance gains for applications on high-end compu...
