Description Jarod Wilson 2019-07-24 21:38:47 UTC
Upstream mpich 3.3.0 was released back in September of 2018, and a 3.3.1 stable update has since been released, and all mpich users are encouraged to upgrade. The new mpich version includes new hardware support for more recent hardware via OFI and UCX modules, which feature much lower CPU overhead with more functionality offloaded to the hardware.

Note: mpich 3.3.x requires hwloc v2.0.x or later as well, so a subsequent bug will be filed requesting that update as well.
