Bug 1397192

This is a regression from 7.2:

# repoquery --whatprovides mpich-devel'(x86-64)'
mpich-devel-0:3.0.4-8.el7.x86_64

Note that mpich-3.0-devel does provide mpich-devel, just not the mpich-devel%{?isa} explicitly required by hypre-mpich-devel in the spec.

True, but the arch specific version is what should be used according to the Fedora packaging guidelines:

The 3.0.4-10.el7 package I'm looking at does, but that gets obsoleted.

The instability of RHEL MPI packages is a huge pain for anyone trying to run a
typical HPC service using them.

No solution for this issue?

Well, in the immediate term - hypre needs to change the requires, assuming that it will take a while to get this fixed in RHEL7.  Something like:

%if 0%{?el7}
# https://bugzilla.redhat.com/show_bug.cgi?id=1397192
Requires:       mpich-devel
%else
Requires:       mpich-devel%{?_isa}
%endif

should do the trick.

Also a possibility - one might want to build both mpich-3.0 and mpich-3.2 versions.

I'll leave these up to Dave.

I don't object to trying to work round problems, but why would this apply only to hypre?  It won't help unless petsc and any other relevant packages change.

Also any mpich packages rebuilt now won't install on CentOS/SL 7 systems as far as I can see.

Because hypre is the only package that (correctly) requires mpich-devel%{?_isa} rather than just mpich-devel:

# repoquery --whatrequires mpich-devel
blacs-mpich-devel-0:2.0.2-15.el7.x86_64
ga-mpich-devel-0:5.3b-14.el7.x86_64
ga-mpich-static-0:5.3b-14.el7.x86_64
gasnet-devel-0:1.28.0-1.el7.x86_64
hypre-mpich-devel-0:2.11.1-4.el7.x86_64
mpich-doc-0:3.0.4-8.el7.noarch
netgen-mesher-mpich-devel-0:5.3.1-5.el7.x86_64
scalapack-mpich-devel-0:2.0.2-15.el7.x86_64
# repoquery --whatrequires mpich-devel'(x86-64)'
hypre-mpich-devel-0:2.11.1-4.el7.x86_64

hypre-2.11.1-6.el7 has been submitted as an update to Fedora EPEL 7. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2016-30fb5f975e

Actually petsc does too, but that list suggests plenty of missing dependencies.

Anyhow, I've pushed the hypre update to testing (and will keep it there until it will install on CentOS/SL).

Does 'petsc' need this fix?
