Launching xterm by mpirun onto a remote platform without a command
simply opens a xterm-window which sits there until you type exit into it
or close it by pressing on the frame's close button.
(of course only if the display is forwarded to the local machine)

Ah, well that might explain it. I don't know how
Hi
Well, the difference is that one time i call the application
'HelloMPI' with the '--xterm' option,
whereas in my previous mail i am calling the application 'xterm'
(without the '--xterm' option)

Hi Ralph
Thank You for doing the fix.
Do you perhaps also have an idea what is going on when i try to start
xterm (or probably an other X application) on a remote host?
In this case it is not enough to specify the '--leave-session-attached' option.
These calls won't open any xterms

Hi Ralph
I rebuilt open MPI 1.4.2 with the debug option on both chefli and squid_0.
The results are interesting!
I wrote a small HelloMPI app which basically calls usleep for a pause
of 5 seconds.
Now calling it as i did before, no MPI errors appear anymore, only the
display problems:

Hi Ralph
Thank you for your suggestions.
I'll be happy to help you.
I'm not sure if i'll get around to this tomorrow,
but i certainly will do so on Monday.
Thanks

Hi Jody
I'm not sure when I'll get a chance to work on this - got a deadline to meet. I
do have a couple of suggestions, if you wouldn't mind helping debug the problem?
It looks to me like the problem is that mpirun is crashing or terminating early
for some reason - hence the failures to send m
No immediate suggestions - I won't get a chance to test this until later as I
don't normally run an x11 server on my box, and don't have another way to test
it.

Hi
Unfortunately this does not solve my problem.
While i can do
ssh -Y squid_0 xterm
and this will open an xterm on m,y machiine (chefli),
i run into problems with the -xterm option of openmpi:
jody@chefli ~/share/neander $ mpirun -np 4 -mca plm_rsh_agent "ssh
-Y" -host squid_0 --xterm 1 hos
Should be able to just set
-mca plm_rsh_agent "ssh -Y"
on your cmd line, I believe

Hi Ralph
Is there an easy way i could modify the OpenMPI code so that it would use
the -Y option for ssh when connecting to remote machines?
Thank You

Hi Ralph
thank you for your suggestions. After some fiddling, i found that after my
last update (gentoo) my sshd_config had been overwritten
(X11Forwarding was set to 'no').
After correcting that, i can now open remote terminals with 'ssh -Y'
and with 'ssh -X'
(but with '-X' is till get those xaut

Sorry Jody - I should have read your note more carefully to see that you
already tried -Y. :-(
Not sure what to suggest...

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:
If I read your error messages correctly, it looks like mpirun is crashing - the
daemon is complaining that it lost the socket connection back to mpirun, and
hence will abort.
Are you seeing mpirun still alive?

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
20 matches
