MPICH 4.1a1 released
by Zhou, Hui 06 May '22

06 May '22

We are pleased to announce that we have just released MPICH 4.1a1. It is available at https://www.mpich.org/downloads/. This release is the first alpha release for 4.1 release series. Major features include PMI refactor, MPIX stream experimental API, build and testing enhancements, and many fixes and improvements. In addition to the usual mpich and hydra tarballs, starting with this release, we also release libpmi and mpich-testsuite tarballs for use cases outside MPICH. The MPIX stream prototypes are experimental ideas to address explicit mapping of execution context for MPI+thread and MPI+CUDA applications. For more information, see https://github.com/pmodels/mpich/discussions/5908. Discussions and feedback are welcome.
