FYI: pursuant to the objectives outline last year, I have committed PR #7202 and removed ORTE from the OMPI repository. It has been replaced with a PRRTE submodule pointed at the PRRTE master branch. At the same tie, we replaced the embedded PMIx code tree with a submodule pointed to the PMIx master branch.
The mpirun command hasn't changed. It simply starts PRRTE under the covers and then launches your job (using "prun") against it. So everything behaves the same in that regard. Some notes on possible differences: * singletons work, but singleton comm-spawn does not. We will address this in a little while * we haven't extensively tested MCA params and cannot claim that every cmd line option works. There are some MCA params that don't have a PRRTE equivalent. Please let us know when you hit something that appears to be missing. Note that you will need to pull the submodules once you update from the repo, and PRs may well need to be rebased. Ralph
