Non-uniform memory access (NUMA) systems, where each processor has its own memory, have been popular platform in high-end computing. While some early studies had reported that a flat-MPI programming model outperformed an OpenMP/MPI hybrid programming model on SMP clusters, the hybrid of a shared-memory, thread-based programming and a distributed-memory, message passing programming is considered to be a promising programming model on the multi-core multi-socket NUMA clusters. We explore the… CONTINUE READING
