I made a short analysis about the interest shown in the answers in the questionnaire the MPI Forum started at SC09 although this questionnaire cannot be representative. Attached. ----- Original Message -----
From: "RICHARD GRAHAM" <[email protected]> To: [email protected] Sent: Tuesday, May 17, 2011 7:35:58 AM Subject: [Mpi-forum] MPI 3.0 voting Attached is the list of proposals that are under consideration for key features that will gate the MPI-3.0 release. Each organization should vote for 3 items on this list, by sending a note to Jeff Squyres and myself, by end of the day Sunday, 5/22/2011. The top three items will be the gating items for release 3.0.
Rich
- RMA - Significant enhancements to MPI's one-sided communication to incorporate requests from multiple user communities and codification of established practice
- FT stabilization - A proposal that defines semantics for MPI to continue and function upon failure, due to process failure.
- Fortran bindings - improved Fortran bindings, taking into account Fortran 2003 and 2008 features.
- MPI-T - The MPI_T interface, proposed in ticket #266, provides a mechanism for the MPI implementation to expose a set of variables, each of which represent a particular property, setting, or performance measurement from within the MPI implementation. Tools can use this information to help users understand and optimize the configuration of the MPI library and/or the performance of their codes.
- Neighborhood collectives - scalable sparse collective support
- Const - Make the MPI binding const correct
- MPI Count - Add the mpi count type
- Nonblocking collective I/O - extend nonblocking collective support to include MPI-I/O
- Hybrid: Shared memory communicator, Threads, and Endpoint proposals
- Persistence - expand the support for persistent communications, for optimal performance.
The eligible organizations include: - ANL - Bull - Cisco - Cray - Fujitsu - HDF - HLRS - HP - IBM - Indiana U. - INRIA - Intel - LLNL - LANL - Microsoft - NCSA/UIUC - ORNL - OSU - Oracle - SNL - U Alabama Birmingham - U Tennessee - U. Tokyo
