The MPICH team is pleased to announce the availability of a new major release (MPICH-3.0). http://www.mpich.org/ The primary focus of this release is to provide full support for the MPI-3 standard. But other features, such as support for ARM v7 native atomics, are also included. Windows binaries are not available at this time. We are unable to provide an ETA for Windows support right now, but it will probably not be soon. The major additions in the 3.0 release since the 1.5 release are highlighted below. Regards, The MPICH Team =============================================================================== 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.
