I am having troubles running mpiexec (from MPICH 3.1) on remote hosts with xterm (for debugging purposes) from an Ubuntu box.<br>
<br>
The following command works perfectly in local:<br>
mpiexec -n 1 xterm <br>
<br>
However, if I use a machine file: <br>
mpiexec -f macfile -n 1 xterm <br>
xterm Xt error: Can't open display: <br>
xterm: DISPLAY is not set<br>
<br>

X forwarding is activated:<br>
fisaila@howard:bin$ grep X11Forwarding /etc/ssh/sshd_config<br>
X11Forwarding yes<br>
<br>
The following command works:<br>
fisaila@howard:bin$ ssh thwomp.mcs.anl.gov xterm<br>
<br>
Any suggestion how to solve this?<br>
<br>
Thanks<br>
