Since the 1990s, MPI (Message Passing Interface) has been the dominant communications protocol for high-performance scientific and commercial distributed computing. Designed in an era when processors with two or four cores were considered high-end parallel devices, the recent move to processors containing tens to a few hundred cores (as exemplified by the current Intel Xeon and Intel Xeon Phi processor families) has exacerbated scaling issues inside MPI itself. Increased network traffic, amplified by high performance communications fabrics such as InfiniBand and Intel Omni-Path Architecture (Intel OPA) manifest an MPI performance and scaling issue.
In recognition of their outstanding research and …
