Hi Ralph No, after the above error message mpirun has exited. But i also noticed that it is to ssh into squid_0 and open a xterm there:
jody@chefli ~/share/neander $ ssh -Y squid_0 Last login: Wed Apr 6 17:14:02 CEST 2011 from chefli.uzh.ch on pts/0 jody@squid_0 ~ $ xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set jody@squid_0 ~ $ export DISPLAY=130.60.126.74:0.0 jody@squid_0 ~ $ xterm xterm Xt error: Can't open display: 130.60.126.74:0.0 jody@squid_0 ~ $ export DISPLAY=chefli.uzh.ch:0.0 jody@squid_0 ~ $ xterm xterm Xt error: Can't open display: chefli.uzh.ch:0.0 jody@squid_0 ~ $ exit logout same thing with ssh -X, but here i get the same warning/error message as with mpirun: jody@chefli ~/share/neander $ ssh -X squid_0 Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. Last login: Wed Apr 6 17:12:31 CEST 2011 from chefli.uzh.ch on ssh So perhaps the whole problem is linked to that xauth-thing. Do you have a suggestion how this can be solved?
