OpenMPI / MPI transition
Hi,
OpenMPI has a new upstream release 5.0.0. It is in experimental now; the
SOVERSION for libraries remains 40.X (minor version increment), there
is an SOVERSION increment for private libraries only so in theory this
is not an ABI transition. However 5.0.0 drops 32-bit system support.
The default MPI implementation for each architecture is set in
mpi-defaults; this allows a per-arch MPI choice; in practice we
currently use OpenMPI for all archs. The other choice is MPICH.
So the question becomes: do we switch MPI for just 32-bit archs, or all?
What are the release teams opinion on this transition?
regards
Alastair
