I'm thinking about trying to sneak in openmpi 3.1.3 before the f30
branch. My COPR rebuilds have been looking pretty good lately so I hope
it will go fairly smoothly. Does anyone have any objections? I'm
planning on starting tomorrow if not.

Why not 4.0.0? It was released in September 2018 and it's supposedly ABI
compatible with 3.x:
https://www.mail-archive.com/announce@lists.open-mpi.org/msg00119.html
It's a big jump from the currently packaged 2.1.6. Any idea why we are
so behind upstream? 3.0.0 was released in September 2017, 3.1.0 in May
2018. 3.0.0 should have been in F27 or F28 and 3.1.0 in F29 latest.
Also, they say 2.1.6 is the last release in 2.1.x series, so I'd say
an update to a supported version is a must.

Because it's still relatively new. I've hit enough problems with major
bumps in openmpi to be a little wary. And I don't have the COPR testing
record for it. We are doing this last minute so I'm trying to be a
little more careful.

Because no one else has stepped up to help maintain it and I'm stretched
too thin.

I concur as well.

I guess you haven't tried it :-/. It may be ABI compatible, but it's
not API compatible (at least by default); that's apart from the usual
sort of breakage you expect from a major version. I've wasted too much
time on it, and given up locally for now.
I wish there was an MPI one could be happy with, providing the
flexibility of OMPI without the maintenance issues.

Indeed, I haven't.

Understood. I guess the way forward is to update to latest 3.1.x now
and start working on 4.0.0 after F30 is branched in COPR. I might be
able to lend a hand or two. ;)

Seconded. For example, there are subtle differences between MPICH and
OpenMPI regarding MPI_OFFSET_KIND int type on 32bit arches and neither
upstream considered changing to be consistent with the other:
https://github.com/open-mpi/ompi/issues/4846
https://github.com/pmodels/mpich/issues/3002
I'm sure there are other pitfalls as well.

Building now. Will start dependent builds when it is complete.

No objections from me. Please do let me know if I can help.
