I truly appreciate your patience. Let me talk to some of our Bproc folks and see if they can tell me what is going on. I agree - I would have expected the NODES to be 0,1. The fact that you are getting just 0 explains the behavior you are seeing with Open MPI.
I also know (though I don't the command syntax) that you can get a long-term allocation from bjs (i.e., one that continues until you logout). Let me dig a little and see how that is done. Again, I appreciate your patience. Ralph On 11/2/06 6:32 AM, "hpe...@infonie.fr" <hpe...@infonie.fr> wrote: > I again Ralf, > >> I gather you have access to bjs?
