Hello All,

I'm using Open MPI 1.10.3 with Slurm and would like to ask how do I find out if pmi1 or pmi2 was used for process launching? The Slurm installation is supposed to support both pmi1 and pmi2, but I would really like to know which one I fall in to. I tried using '-mca plm_base_verbose 100' on the mpirun line, but it didn't mention pmi specifically. Instead, all I could really find was that it was using the slurm component. Is there something else I can look at in the output that would have that detail?

Thank you for your time,
