Has anyone been able to run an MPI job using PMIX and heterogeneous jobs
successfully with 19.05 (or even 18.08)? I can run without heterogeneous jobs
but get all sorts of errors when I try and split the job up.
I haven't used MPI/PMIX much so maybe I'm missing something? Any ideas?

Works here on slurm 18.08.8, pmix 3.1.2. The mpi world ranks are unified as
they should be.
$ srun --mpi=pmix -n2 -wathos ./hello : -n8 -wporthos ./hellosrun: job 586

Well it looks like it it does fail as often as it works.
