Re: [slurm-dev] Passing MCA parameters via srun
Paul,
If the user always want a specific set of MCA options, then they
should be placed in $HOME/.openmpi/mca-params.conf
Otherwise, one should use environment variables with the prefix OMPI_MCA_
A far more complete answer is here:

Typically on our cluster we use:
srun --mpi=pmi2
To launch MPI applications as we have task affinity turned on and
we want to ensure that the binding works properly (if we just
invoke mpirun it doesn't bind properly). One of our users wishes
to pass in more options to srun to tune MPI (specifically OpenMPI
1.10.2) such as to standard MPI options:
mpirun -mca btl self,openib
My question is how do I get slurm to pass these options through
when it invokes MPI.
