MTT -
- If you change your MTT to startup PRRTE at begining of session, and just use prun.
- Can see times cut in half or more.
- This is good, but also need to test mpirun wrapper.
- Cisco is converting half of MPI installs to use prrte/prun
-
OMPI master submodule pointers setup to track PMIx and PRRTE master.
- Jeff discussed an idea to have some integration with PRRTE that putting a string in a PRRTE PR would automatically open an Open-MPI PR to update the PRRTE submodule after that PRRTE PR is merged to PRRTE master.

- Biggest thing on master is prrte.
- Issues are being found and fixed.
- Cisco mtt failing due to -np
- Might see more failures on master tonight.
- Maybe mid-late summer. No discussion
- scale-testing, PRs have to opt-into it.
Review Master Master Pull Requests
- CI testing only tests build and did it run, but doesn't test HOW it ran.
- Environment setup can be a bit different.
- For example no-permissions in
/tmp. Might pass on one machine, and fail on another without/tmppermissions.
