Riccardo,
I am a bit confused by your explanation.
Open MPI does embed PMIx, but only for itself.
An other way to put it is you have to install pmix first (package or
download from pmix.org)
and then build SLURM on top of it.
Then you can build Open MPI with the same (external) PMIx or t
Rick,
The issue is SLURM can only provide pmi2 support, and it seems Open MPI
only supports pmix
One option is to rebuild SLURM with PMIx as explained by Daniel, and then
srun --mpi=pmix ...
If you do not want (or cannot) rebuilt SLURM, you can use the older pmi
or pmi2.
In that case,
Christopher,
This looks like a SLURM issue and Open MPI is (currently) out of the
picture.
What if you
srun --pack-group=0,1 hostname
Do you get a similar error ?
Cheers,
Gilles
