Hi Rolf,
Thanks for that. There is still one minor problem,
though. The xwindow is getting spawned on the remote machine and not
on my local machine. It now looks like,
mpirun --prefix /usr/local -hostfile machines -x DISPLAY -x PATH -
np 2 xterm -e gdb peruse_ex1
Please let me know what i can do to have it displayed on
my machine. I have the DISPLAY variable set to 0.0 on both the
machines and I am ssh-ing into the other machine by using the -X
switch.
Thanks,
Krishna Chaitanya

I also do the the following:
-x DISPLAY -x PATH
In this way, both your DISPLAY and PATH settings make it to the
remote node.
