Vader Issue 6014 - Aquire thread fence anywhere we're using the sync buildin primatives.
- Symptom is hang.
- Reproducer is tight loop on barrier
- Need a FAQ entry on this.
- Workaround is
--disable-builtin-atomics- no real downside from doing this.
- 3.x, 4.x, maybe 2.1.x?
- master wasn't affected because it uses C11 by default.
- Wherever this goes back to, we need to update PMIx there to, since same code.
- End of the day, this will drive a new release on v2.x, v3.0 and 3.1
-
Face to Face was next week
-
