Abstract. Most parallel systems on which MPI is used are now hierarchical: some processors are much closer to others in terms of interconnect performance. One of the most common su...

We describe a generic programming model to design collective communications on SMP clusters. The programming model utilizes shared memory for collective communications and overlap...
MPI provides a portable message passing interface for many parallel execution platforms but may lead to inefficiencies for some platforms and applications. In this article we sho...
