Hi,
I made a minor mess in the mpich world and instead of upgrading to
3.3.1 from 3.2.1., I built 3.1.1. I was a bit surprised when I got
a bug [1] that mpich in Fedora is from 2014 :(
I'd like to update to 3.3.1, but that needs newer hwloc which has an
so-bump.
There's a number of users of hwloc:
mpich
pmix
openmpi
pocl
slurm
hpx
legion
aircrack-ng
gromacs
They all build fine with hwloc 2.0.4, except from legion.
Legion is incompatible.
I came up with a patch to partially disable hwloc use [2],
and after reporting the issue upstream, I got the feedback
that this is the correct approach [3].

As a stop-gap measure, I rebuilt mpich-3.2.1 again today in
rawhide and F31. I'd like to do the update though.
I plan to build hwloc-2.0 and the packages listed above, incl. legion
with the patch on Wednesday.

Sounds good to me. Thanks for taking this on.
