Subject: Re: [OMPI users] [EXTERNAL] Re: (OpenMPI for Cray XE6 ) How to set mca parameters through aprun?
From: Nathan Hjelm (hjelmn_at_[hidden])

Ok, that sheds a little more light on the situation. For some reason it sees 2 nodes
apparently with one slot each. One more set out outputs would be helpful. Please run
with -mca ras_base_verbose 100 . That way I can see what was read from alps.
