[mpiwg-sessions] MPICH/hydra happier with Dan's test cases (kind of)

[HOLMES Daniel]

Hi Howard, et al,

Howard: thanks for checking this on MPICH. Looks like we need a cross-mpirun example code - we could work on that this week.

All: *reminder* no telecon today - we’ll meet up during the MPI Forum in a couple of days.

Cheers,
Dan.

Hi Folks,

I made some minor corrections to the two problem test cases and they now work
with mpich.  I opened a PR and assigned Dan as the reviewer.

Subject: [mpiwg-sessions] MPICH/hydra happier with Dan's test cases (kind of)

HI Folks,

MPICH/hydra is happy with libCFG_noMCW, even with all the sleeps
removed. I ran up to 36 ranks with hydra/mpich and didn’t see a problem.

Its not so happy with the other tests, I think they are buggy.

Here’s what I get for libCFG_noMCW_multiport

If I have a chance I”ll play with this test and see if I can get it to work.  hmm.. maybe hydra doesn’t like the whitespace publish names.
