Abstract
High Performance Computing (HPC) is the key to solving many scientific, financial, and
engineering problems. Computer clusters are now the dominant architecture for HPC. The scale
of clusters, both in terms of processor per node and the number of nodes, is increasing rapidly,
reaching petascales these days and soon to exascales. Inter-process communication plays a
significant role in the overall performance of HPC applications. With the continuous
enhancements in interconnection technologies and node architectures, the Message Passing
Interface (MPI) needs to be improved to effectively utilize the modern technologies for higher
