You must have executed lamboot before this, right? Did you lamboot with a hostfile spanning multiple nodes? I'm guessing that you ran "lamboot" with no arguments, which defaults to only creating a LAM run-time environment on the localhost. If you give it a hostfile, then you tell LAM what nodes to run on (i.e., subsequent mpirun's will use those nodes). You might want to look through the abbreviated LAM documentation in the OSCAR User's Guide, or look at the full LAM/MPI User's Guide (http://www.lam-mpi.org/using/docs/) -- there's a nice tutorial and "getting started with LAM/MPI" section in there. Hope that helps. On Jan 28, 2005, at 7:10 PM, Rajiv wrote: > Dear Jeff, > 1. I am running the with the default LAM-MPI that comes with fedora > core-2. > 2.
