Is there a way to change the remote access method from rsh to ssh (specifically, "ssh -x") for debugging MPICH programs using mpch_gdb.idb (as, for example, the MPICH ./configure option RSHCOMMAND="ssh -x")? The idb -remote option does not seem to apply in this case, as I read the documentation. Can one create a shell script called rsh that replaces the rsh executable which calls "ssh -x $@"? If so, where should that be located, i.e., how does idb invoke rsh?
