I am having troubles running mpiexec (from MPICH 3.1) on remote hosts with xterm (for debugging purposes) from an Ubuntu box.
The following command works perfectly in local:
mpiexec -n 1 xterm
However, if I use a machine file:
mpiexec -f macfile -n 1 xterm
xterm Xt error: Can't open display:
xterm: DISPLAY is not set
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= PID 19225 RUNNING AT thwomp.mcs.anl.gov
= EXIT CODE: 1
= CLEANING UP REMAINING PROCESSES
= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
X forwarding is activated:
fisaila at howard:bin$ grep X11Forwarding /etc/ssh/sshd_config
The following command works:
fisaila at howard:bin$ ssh thwomp.mcs.anl.gov xterm
Any suggestion how to solve this?
