[mvapich-discuss] environment variable for using rsh as default mpirun_rsh's bootstrap?

[Jonathan Perkins]

Hello, there are two things that you can try out.  Since you've
already built the library you can create an alias for mpirun_rsh so
that it is always mpirun_rsh --rsh.  Try put the following in your
.bashrc if you're using bash.

alias mpirun_rsh='mpirun_rsh --rsh'

The other thing that you can try if you don't mind rebuilding is using
the --enable-rsh option at configure time.

./configure --enable-rsh ...
