Did you try passing -enable-x to mpiexec?

Hi,

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

X forwarding is activated: fisaila@howard:bin$ grep X11Forwarding /etc/ssh/sshd_config X11Forwarding yes

The following command works: fisaila@howard:bin$ ssh thwomp.mcs.anl.gov xterm

Any suggestion how to solve this?

Thanks Florin
