Re: [OMPI users] Using Open MPI with PBS Pro

I’ve never heard of that, and cannot imagine what it has to do with the 
resource manager. Can you point to where you heard that one?

FWIW: we don’t ship OMPI with anything in the default mca params file, so 
somebody must have put it in there for you.

Hi Ralph,

I think I found that information at 
 :-)


In any case, thanks for the information about the default params file -- 
I won't worry too much about modifying it then.

Can we also disable that in other cases, like Slurm, or is this something 
specific to PBS Pro?

Ah yes - that was a case where someone had added an incorrect param to the 
default file, and we suggested they remove it
