- a bunch of PRs open against master, and some of them may need fixed on 1.10.x
- Detecting failures None of the MTT we run nightly, are running MPICH at night.
- We should add MPICH to nightly runs

- 1064 - Ralph / Jeff, is this do-able by december?
- Dynamic add procs is busted now when set value to 0 (not related to PMI-x)
- A bunch of paths, that may fix this... don't know yet.
- External Linage issue
- Distros won't accept Open MPI without external linkage to ?
- first time we have a part of Open MPI that has an external linkage to libevent.
- in the past the App was using libevent (version different than internal usage)
- Solved by renaming symbols in internal version.
- Problem now is that we have another part of Open MPI (PMPI-x) that also links against libevent.
- If we remove embedded version of libevent, that would be okay.
- it's when we build against internal version of libevent, then PMI-x ???
- One solution is to no longer package libevent with Open MPI.
- Reason we package it, is so that people don't have to download libevent along with Open MPI.
- Now libevent-pthread is available on most intros.
- We DO require libevent to be thread enabled. and check for this in configuration,
- No performance implications.
- Distros won't accept Open MPI without external linkage to ?
- Debugger support is broken on Master and on 2.x
- Ralph needs version PMIx 1.2 to do it.
- He thinks he can come up with a solution in the January time frame.
- If we start to use PMI-x for the debugger, then the proc could tell a resource manager that they want to be debugged.
