Please try using --mca pls_rsh_assume_same_shell 0 -- to check for the shell on the node, it should detect the ksh on the node being used from the $SHELL env-variable. To check, You may also use: ssh <nodename> echo $SHELL > There are no problems at all under bash. (I use bash and I had no > trouble, but then started switching some users who were having MPICH > problems and they could not get it to work unless they changed to bash.) In case it does not detect the correct value and set the environment variables, could You please use --mca orte_debug 1 --mca pls_rsh_debug 1 and send the output?
