For SLURM, there is a config file where you can specify what gets propagated. It is clearly an error to include hostname as it messes many things up, not just OMPI. Frankly, I've never seen someone do that on SLURM.
Well, it's USUALLY an error .... That's clearly a good solution.
I believe in this case OMPI is likely incorrectly picking up the environment and propagating it. We know this is incorrectly happening on Torque, and it appears to also be happening on SLURM. This is a bug that I will be fixing on Torque - and as soon as Nadia confirms, on SLURM as well.
I should have run a cross-check! It doesn't happen on my bare OpenMPI installation. Regards, Nick Maclaren.
