Announcing the availability of MPICH 3.3a2
by Kenneth Raffenetti 13 Nov '16

13 Nov '16

A new preview release of MPICH, 3.3a2, is now available for download. This preview release is for the 3.3 major release series. Of major focus in this alpha is an new (non-default) device layer implementation - CH4. CH4 is designed for low software overheads to better exploit next-generation hardware. An OFI (http://libfabric.org) or UCX (http://openucx.org) library is required to build CH4. Example configure lines: ./configure --with-device=ch4:ofi --with-libfabric=<path/to/ofi/install> ./configure --with-device=ch4:ucx --with-ucx=<path/to/ucx/install> CH4 is still in alpha stages, meaning there are known build issues and bugs, but most tests and common benchmarks will complete on 64-bit Linux systems. Since 3.3a1, there have been major stability improvements, bug fixes, and code cleanup in CH4. CH4 support for Blue Gene/Q is added in this release (via the OFI/BGQ provider), as well as Mac OS builds. Also in this release are several bug fixes and improvements to CH3, Hydra, and common MPICH code. You can find the release on our downloads page (http://www.mpich.org/downloads) Regards, The MPICH team =============================================================================== Changes in 3.3 =============================================================================== # CH4 Device: A new device layer implementation designed for low software overheads. CH4 has experimental support for OFI and UCX network libraries, and POSIX shared memory. Thanks to Intel, Mellanox, and RIKEN AICS for participating in the CH4 coding effort. # Removed the PAMI device and poe PMI client. # Several other minor bug fixes, memory leak fixes, and code cleanup. A full list of changes is available at the following link: http://git.mpich.org/mpich.git/shortlog/v3.2..v3.3a2 A full list of bugs that have been fixed is available at the following link: https://github.com/pmodels/mpich/milestone/25

Announcing the availability of Casper 1.0b1
by Min Si 13 Nov '16

13 Nov '16

We are proud the announce the first preview release of Casper (1.0b1). Please visit the Casper homepage for download. http://www.mcs.anl.gov/project/casper/ Casper is a process-based asynchronous progress model for MPI one-sided communication. It allows the user to keep aside a small number of cores on a multicore or many-core environment as "ghost processes," which are dedicated to help asynchronous progress for user processes through appropriate memory mapping from those user processes. Casper is designed as an external library through the PMPI name-shifted profiling interface of MPI, it can transparently link with most MPI implementation that supports MPI-3.0 RMA features. Best Regards, The MPICH team

Announcing the availability of Argobots 1.0a1 and BOLT 1.0a1
by Seo, Sangmin 12 Nov '16

12 Nov '16

Preview releases of Argobots (1.0a1) and BOLT (1.0a1) are now available for download here: http://www.argobots.org/downloads/ http://www.bolt-omp.org/downloads/ Argobots is a lightweight low-level threading and tasking infrastructure and can be used as a low-level threading mechanism for diverse high-level programming models or domain-specific libraries. BOLT is a high-performing OpenMP implementation that utilizes Argobots as the primary threading model. With the ABI compatibility with the Intel OpenMP runtime, BOLT can be used with LLVM/Clang, Intel OpenMP compiler, or GCC with a simple LD_PRELOAD environment change (no recompilation needed).

move to GitHub
by Kenneth Raffenetti 17 Oct '16

17 Oct '16

Hi folks, MPICH has moved to GitHub! http://github.com/pmodels/mpich Come check us out at the new location. We have imported all existing tickets from our old bug tracker as GitHub issues. New bugs (and pull requests) can be submitted directly to GitHub repo. The old MPICH git repositories at git.mpich.org are still available, and will be kept in sync with the official master branch. This may change in the future as we evaluate their utility. Please contact me if you have any questions at this time. Our developer wiki (http://wiki.mpich.org) will be updating over the coming weeks with new information, so feel free to point out any mistakes, omissions, etc. Thanks and enjoy! Ken
