Hopefully PMI/PMI2/PMIx decreases the startup time! :-) There's a presentation on PMIx (the latest version) here: https://slurm.schedmd.com/SC17/PMIx-SC17.pdf You need to be careful about the versioning with PMIx and Slurm versions, there is information on getting it working on both sites: https://slurm.schedmd.com/mpi_guide.html#pmix https://pmix.org/support/how-to/slurm-support/ Hope this helps!
