Can you mpirun non-MPI applications, like "hostname"? I frequently run this
as a first step to debugging a wonky install. For example:
shell$ hostname
ba
I run a program with the following command line, and obtain the error message
mpirun -x LD_LIBRARY_PATH=/home/haoanyi1/socIntel/goto --prefix
/home/haoanyi1/openmpi1.4.1 -np 2 -host intel01,intel02 -rf hosts ./main 62 62

Yes, I can do all of these on each node.
