We're going to make Open MPI Great Again!!!!
(don't shoot me please)
Thanks to all who provided their opinion.
Based on the results, the Open MPI developer community will work on
v3.0.0 after the v2.1.x series.

Hello Folks,
This is a followup to the question posed at the SC’16 Open MPI BOF:
Would the community
prefer to have a v2.2.x limited feature but backwards compatible
release sometime
in 2017, or would the community prefer a v3.x (not backwards
compatible but potentially
more features) sometime in late 2017 to early 2018?
BOF attendees expressed an interest in having a list of features
that might make it in to v2.2.x
and ones that the Open MPI developers think would be too hard to
back port from
the development branch (master) to a v2.2.x release stream.
Here are the requested lists:
Features that we anticipate we could port to a v2.2.x release
• Improved collective performance (a new “tuned” module)
• Enable Linux CMA shared memory support by default
• PMIx 3.0 (If new functionality were to be used in this release of
Open MPI)
Features that we anticipate would be too difficult to port to a
v2.2.x release
• Revamped CUDA support
• MPI_ALLOC_MEM integration with memkind
• OpenMP affinity/placement integration
• THREAD_MULTIPLE improvements to MTLs (not so clear on the level of
difficult for this one)
You can register your opinion on whether to go with a v2.2.x release
next year
or to go from v2.1.x to v3.x in late 2017 or early 2018 at the link

Thanks very much,
Howard
