MPI Forum: The New MPI 2.1 Standard, and Progress toward MPI 2.2 and 3.0Primary Session Leader:
Rich Graham (Oak Ridge National Laboratory)
Secondary Session Leader:
The Message Passing Interface (MPI) 2.0 standard has served the parallel technical and scientific applications community well over the last decade, and has become the ubiquitous communications API for this community. New technical challenges, such as the emergence of high performance RDMA network support, the need to address scalability at the Peta-Scale order of magnitude, fault-tolerance at scale, and the many-core crisis, require us to rethink MPI's support for this community, and others. This work will be encapsulated in MPI-30. The MPI Forum, chaird by Richard Graham from Oak Ridge National Laboratory, is meeting to revise the MPI standard. MPI-2.1, which consolidates previous documents, has just been ratified. It is also working on near-term incremental changes for MPI-2.2, and longer term on bigger changes for MPI-3.0. This BoF will provide an overview of standardization efforts, provide an opportunity for feedback, and a means to of joining this process.
