 New and old Features in MPI-3.0: The Past, the Standard, and the Future

(Presentation - presented in Munich, Germany, Apr. 2012)

Abstract

The Message Passing Interface (MPI) became the de-facto standard for large-scale parallel programming since MPI-1 was ratified nearly two decades ago. Shortly after, MPI-1 was extended, adding support for I/O and One-Sided (RMA) operations in MPI-2. Ten years later, the Forum reconvened to discuss further extensions to MPI. MPI-2.2 was released in 2008 with mostly bugfixes but also a significant enhancement to the topology chapter which enables scalable MPI process mapping. The Forum is now working towards MPI-3.0 which is in its final stages. This talk will discuss new key features of MPI-3.0 and their anticipated use and benefit. We will discuss the user's, the implementer's, and sometimes the "standardese" perspective on the proposed features. The list includes nonblocking and neighborhood collectives, matched probe, the new One Sided operations and semantics including shared memory windows, and new communicator creation functions in depth.
