Hi
On my workstation and the cluster i set up OpenMPI (v 1.4.2) so that
it works in "text-mode":
$ mpirun -np 4 -x DISPLAY -host squid_0 printenv | grep WORLD_RANK
OMPI_COMM_WORLD_RANK=0
OMPI_COMM_WORLD_RANK=1
OMPI_COMM_WORLD_RANK=2
OMPI_COMM_WORLD_RANK=3
but when i use the -xterm option to mpirun, it doesn't work
$ mpirun -np 4 -x DISPLAY -host squid_0 -xterm 1,2 printenv | grep WORLD_RANK
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Warning: No xauth data; using fake authentication data for X11 forwarding.
OMPI_COMM_WORLD_RANK=0
[squid_0:05266] [[55607,0],1]->[[55607,0],0]

/usr/bin/xterm Xt error: Can't open display: chefli.uzh.ch:0.0
/usr/bin/xterm Xt error: Can't open display: chefli.uzh.ch:0.0
(strange: somebody wrote his message to the console)
No matter whether i set the DISPLAY variable to the full hostname of
the workstation,
to the IP-Adress of the workstation or simply to ":0.0", it doesn't work
But i do have xauth data (as far as i know):
On the remote (squid_0):
jody_at_squid_0 ~ $ xauth list
chefli/unix:10 MIT-MAGIC-COOKIE-1 5293e179bc7b2036d87cbcdf14891d0c
chefli/unix:0 MIT-MAGIC-COOKIE-1 146c7f438fab79deb8a8a7df242b6f4b
chefli.uzh.ch:0 MIT-MAGIC-COOKIE-1 146c7f438fab79deb8a8a7df242b6f4b
on the workstation:
$ xauth list
chefli/unix:10 MIT-MAGIC-COOKIE-1 5293e179bc7b2036d87cbcdf14891d0c
chefli/unix:0 MIT-MAGIC-COOKIE-1 146c7f438fab79deb8a8a7df242b6f4b

chefli.uzh.ch/unix:0 MIT-MAGIC-COOKIE-1 146c7f438fab79deb8a8a7df242b6f4b
In sshd_config on the workstation i have 'X11Forwarding yes'
I have also done
xhost + squid_0
on the workstation.
How can i get the -xterm option running?
Thank You
Jody
