Hi For debugging i usually run each process in a separate X-window. This works well if i set the DISPLAY variable to the computer from which i am starting my OpenMPI application.
This method fails however, if i log in (via ssh) to my workstation from a third computer and then start my OpenMPI application, only the processes running on the workstation i logged into can open their windows on the third computers. The processes on the other computers cant open their windows. This is how i start the processes mpirun -np 4 -x DISPLAY run_gdb.sh ./TestApp where run_gdb.sh looks like this ------------------------- #!/bin/csh -f echo "Running GDB on node `hostname`" xterm -e gdb $* exit 0 ------------------------- The output from the processes on the other computer: xterm Xt error: Can't open display: localhost:12.0 I there a way to tell OpenMPI to forward the X windows over yet another ssh connection? Thanks Jody
