Subject: [OMPI devel] oshmem test suite errors
From: Jeff Squyres (jsquyres) (jsquyres_at_[hidden])

For all of these, I'm using the openshmem test suite that is now committed to the ompi-svn SVN repo. I don't know if the errors are with the tests or with oshmem itself.

1. I'm running the oshmem test suite at 32 processes across 2 16-core servers. I'm seeing a segv in "examples/shmem_2dheat.x 10 10". It seems to run fine at lower np values such as 2, 4, and 8; I didn't try to determine where the crossover to badness occurs.

2. "examples/adjacent_32bit_amo.x 10 10" seems to hang with both tcp and usnic BTLs, even when running at np=2 (I let it run for several minutes before killing it).

3. Ditto for "example/ptp.x 10 10".

4. "examples/shmem_matrix.x 10 10" seems to run fine at np=32 on usnic, but hangs with TCP (i.e., I let it run for 8+ minutes before killing it -- perhaps it would have finished eventually?).

...there's more results (more timeouts and more failures), but they're not yet complete, and I've got to keep working on my own features for v1.7.5, so I need to move to other things right now.

I think I have oshmem running well enough to add these to Cisco's nightly MTT runs now, so the results will start showing up there without needing my manual attention.
