Open MPI Weekly Telcon

What's going on with --disable_dlopen failure. Recent PRs are getting Xed due to an undefined ref with --disable_dlopen on yoohoo cluster.
- Giles posted on a couple, that it looks like a dirty tree. Failure is it can't copy bits to m4 directory.
- Howard see, when it links hello_world it looks like it fails with unsat symbol.
- Don't see this issue in v2.0
- The symbol is opal_declspeced
- Perhaps it's several things going on.
- PR2885 - PMIx 2885 - red X on disable_dlopen.
- No one can hit this by hand (jeff and Ralph both tried). GCC 4.85 and 4.81.
Ralph is working on update to PMIx Master that will have pthread_locking fix.
- If that's okay, Ralph will add new PR to roll PMIx Master into OMPI 2.1.1 (within a few days)
Mellanox has some PRs for v2.1.
- want to resolve issues with CI before we Pull more PRs.
Estimated Schedule: Middle of March.

PR2861 - Stack traces - ready to go. Josh Hursey
- Custom one for v2.x branch - Ralph signed off on both.
Support Datatypes - most for master look like they've gone through CI. Waiting for someone to click merge.
Nathan's thread perf fix was cleared.
PR2838, - removal of -heterogeneous configure option.
- If someone can fix it, we should keep it... depend on how risky the fix is.
- Is it being tested? @ggouaillardet is testing nightly, just not uploading data to MTT.
- If @ggouaillardet agress to fix it, and upload tests to MTT nightly on hetrogeneous cluster, then no reason to remove the support for us.

Got some fixes committed upstream to OSHMEM
- some new tests are supposed to HANG / Timeout.
- Jeff submitted request to them to help MTT hook into this new test use-case.
MPI_ONE_SIDED + MPI_THREAD_MULTIPLE
- Abort rather than wrong answer when component doesn't want to run due to lack of component.
- osc_pt2pt - Nathan has fix wants IBM to test.

Been going kinda slow lately. Intel committed some code to be able to report to the database.
Ralph is going to switch to Python client to post to MTT database.
Ralph's been asked to provide 3 other components:
- Watchdog timer to Kill off hung jobs.
- A harass launch other side procs to do nasty thing
- Nightly regression on the DBM - starts DBM, and launch tests against DBM. Will run MTT in half the time.

SPI - got a reply on how to initiate, Cisco has the ball.
- Added SPI to website.
Github transitioned us to a free account.
