I'm the one who's found that problem. I've had this happen with several
versions. mvapich that comes with the system and the mvapich2-1.5.1
that I downloaded and compiled myself.
The 1.5.1 version works if I run locally, probably because it's not
using ssh? But if I try to run on a remote node I get the same error.
For example:
node1 $ mpirun_rsh -np1 node1 mpiProgram -> works
node1 $ mpirun_rsh -np1 node2 mpiProgram -> fails
Also, if I go on a node where this still works, I can still run on the
"bad" remote nodes. For example
nodeGood $ mpirun_rsh -np1 node2 mpiProgram -> works
node1 $ mpirun_rsh -np1 node2 mpiProgram -> does not
