I'd really like to hear from upstream users whether they are still
encountering OpenMPI issues.
Personally I favour splitting, using MPICH on 32-bit archs to flush
out bugs, and doing so early in the dev cycle (now) so there is time
to change if necessary.
Thank you both for your comments.
I don't think as the Release Team we have a preference one way or the
other. We'll let you pick the approach that you consider better.
Obviously the freeze is still a long ways off, so if something comes
up it can be changed later.
Cheers,
Emilio
