Abstract

The Message Passing Interface (MPI) 2.1 standard (http://www.mpi-forum.org) has served the parallel technical and scientific applications community well over the last decade, and has become the ubiquitous communications application programming interface for this community. However, this extensive use has also exposed areas where this standard can be strengthened to meet the challenges of emerging ultra-scale computing. This talk will describe the changes introduced to the standard in latest version of the MPI standard, 2.2, and current work targeting version 3 of this standard.
