[Rocks-Discuss] display from compute nodes using qlogin

[Doll, Margaret Ann]

I am trying to run comsol, a chemistry graphics program, from qlogin.

I get java errors, but I found I also cannot run "xclock" from a qlogin
session. I have installed the necessary software for xclock on the compute
nodes including libxkbfile, blifontenc, libfontenc-devel and xorg-x11-apps.

The error with xclock is

[mdoll@compute-0-6 ~]$ xclock &
[1] 16412
[mdoll@compute-0-6 ~]$ Error: Can't open display:

[1]+ Exit 1 xclock

I used

ssh -Y mdoll@clusterhost
qlogin -pe queue 1

to enter into the qlogin session.

I have added

ForwardX11Trusted yes

to the /etc/ssh/ssh_config file on the clusterhost

mdoll is not a member of the xusers group on the queue. This account is
just listed on the users group.

Dear Doll,
You can view the topic which i have submitted - qlogin can not
forward X11 in rocks 5.*.It should be the solution.
Changing SGE settings by the following command:

# qconf -mconf global
> qlogin_command /opt/gridengine/bin/rocks-qlogin.sh
> qlogin_daemon /usr/sbin/sshd -i

Just go to:

That didn't work.

I get

qlogin -pe chemistry 1

Sorry, That was stupid on my part.

Thanks, everyone. The graphics from the compute nodes is working.
