Update to MPICH 3.0.1 =============================================================================== Changes in 3.0 =============================================================================== # MPI-3: All MPI-3 features are now implemented and the MPI_VERSION bumped up to 3.0. # OVERALL: Added support for ARM-v7 native atomics # MPE: MPE is now separated out of MPICH and can be downloaded/used as a separate package. # PM/PMI: Upgraded to hwloc-1.6 # Several other minor bug fixes, memory leak fixes, and code cleanup. A full list of changes is available using: svn log -r10344:HEAD https://svn.mcs.anl.gov/repos/mpi/mpich2/tags/release/mpich-3.0 ... or at the following link: https://trac.mcs.anl.gov/projects/mpich2/log/mpich2/tags/release/mpich-3.0?action=follow_copy&rev=HEAD&stop_rev=10344&mode=follow_copy =============================================================================== Changes in 1.5 =============================================================================== # OVERALL: Nemesis now supports an "--enable-yield=..." configure option for better performance/behavior when oversubscribing processes to cores. Some form of this option is enabled by default on Linux, Darwin, and systems that support sched_yield(). # OVERALL: Added support for Intel Many Integrated Core (MIC) architecture: shared memory, TCP/IP, and SCIF based communication. # OVERALL: Added support for IBM BG/Q architecture. Thanks to IBM for the contribution. # MPI-3: const support has been added to mpi.h, although it is disabled by default. It can be enabled on a per-translation unit basis with "#define MPICH2_CONST const". # MPI-3: Added support for MPIX_Type_create_hindexed_block. # MPI-3: The new MPI-3 nonblocking collective functions are now available as "MPIX_" functions (e.g., "MPIX_Ibcast"). # MPI-3: The new MPI-3 neighborhood collective routines are now available as "MPIX_" functions (e.g., "MPIX_Neighbor_allgather"). # MPI-3: The new MPI-3 MPI_Comm_split_type function is now available as an "MPIX_" function. # MPI-3: The new MPI-3 tools interface is now available as "MPIX_T_" functions. This is a beta implementation right now with several limitations, including no support for multithreading. Several performance variables related to CH3's message matching are exposed through this interface. # MPI-3: The new MPI-3 matched probe functionality is supported via the new routines MPIX_Mprobe, MPIX_Improbe, MPIX_Mrecv, and MPIX_Imrecv. # MPI-3: The new MPI-3 nonblocking communicator duplication routine, MPIX_Comm_idup, is now supported. It will only work for single-threaded programs at this time. # MPI-3: MPIX_Comm_reenable_anysource support # MPI-3: Native MPIX_Comm_create_group support (updated version of the prior MPIX_Group_comm_create routine). # MPI-3: MPI_Intercomm_create's internal communication no longer interferes with point-to-point communication, even if point-to-point operations on the parent communicator use the same tag or MPI_ANY_TAG. # MPI-3: Eliminated the possibility of interference between MPI_Intercomm_create and point-to-point messaging operations. # Build system: Completely revamped build system to rely fully on autotools. Parallel builds ("make -j8" and similar) are now supported. # Build system: rename "./maint/updatefiles" --> "./autogen.sh" and "configure.in" --> "configure.ac" # JUMPSHOT: Improvements to Jumpshot to handle thousands of timelines, including performance improvements to slog2 in such cases. # JUMPSHOT: Added navigation support to locate chosen drawable's ends when viewport has been scrolled far from the drawable. # PM/PMI: Added support for memory binding policies. # PM/PMI: Various improvements to the process binding support in Hydra. Several new pre-defined binding options are provided. # PM/PMI: Upgraded to hwloc-1.5 # PM/PMI: Several improvements to PBS support to natively use the PBS launcher. # Several other minor bug fixes, memory leak fixes, and code cleanup.

MPICH is a freely available, portable implementation of MPI, MPI-2,
and MPI-3 standard message-passing interface.
Add the whole parallel category to pkgsrc, and sprinkle it with a few packages. mpi-ch: a free implementation of the Message Passing Interface. pvm3: Paralell Virtual Machine libraries and environment clusterit: A clustering package for unix
