Hi list,
I am very new to mvapich and I am having problems getting it to run. I
compiled mvapich-0.9.8 on our cluster which runs the Voltaire version of the
OFED stack. To install I simply ran the "make.mvapich.gen2" script after
pointing it to the /usr/local/ofed dir for IBHOME.
I can run a 2 or 4 CPU job on two nodes just fine. The problem happens when
I try to run a 6 or greater CPU job. I get a "Bus error" message. Here it
is running on 2 nodes with 4 CPUs per node.
