[slurm-dev] Re: multiple MPI versions with slurm

[Paul Edmon]

I would build MPI using the pmi libraries and slurm with pmi support.  
Then you can launch any version of MPI using the same srun command and 
leveraging pmi.

Hi all,

I'm trying to provide support to users demanding different versions of
MPI, namely mvapich2 and OpenMPI. In particular, I'd like to support
"srun -n X ./my_parallel_app", maybe with "--with-mpi=X" flag.


Has anybody got any suggestion on how to do that? I'm am kind of new
to cluster administration, so probably there is some obvious solution
that I am not aware of.

Cheers,
