Dear all, I am now setting PC cluster system using gridengine6.2u5 on Ubuntu10.10 server edition. And I met a critical problem which could not solved. Please let me know how to deal with it.
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| <What I would like to do>] ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| PC0: userpc01 (this is operated actually by keyboard/mouse) PC1: yamac01 (qmaster) PC2: yamac02 (node) Note: qmaster and node are different HW each other 1. login to yamac01 with "ssh -X" from userpc01 2. qsub di.csh (a simple script as bellow) with "-V" option [di.csh]====== #!/bin/csh display hoge.png ============ 3. My expected result: hoge.png is displayed on userpc01 via X11 forwarding of SSH. But result is not so. Error file includes this string: "display: unable to open X server `localhost:11.0' @ error/display.c/DisplayImageCommand/424." instead of using 'display' command, 'xterm' result is as followings "xterm Xt error: Can't open display: localhost:11.0" ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| <My question> ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| Does SGE require a special setting or a command option when I use X11 portforwarding? I would like to know the problem is from SGE or SSH or some other settings on Ubuntu. ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| <Some infos for setting SSH> ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| 1. check if a 'ssh_config' includes "ForwardX11 yes" string at both of yamac01 and yamac02. -> OK 2. check if a 'sshd_config' includes "X11Forwarding yes" at both of yamac01 and yamac02. -> OK 3. check if X-window program appears on userpc01 via yamac01(% is command prompt) (commands at userpc01) % ssh -X yamac01 % ssh -X yamac02 xterm then xterm window appeared on userpc01 display. This may mean that 'ssh -X' works well for X11 portforwarding. % ssh -X yamac02 di.csh worked well too. But treating the same job by submitting a script via qsub did not work well. 4. Same as the submitting a X-window process via qsub, qsh did not work well. Xterm from a node did not start up on a userpc01. Please let me know if you have any ideas or some checking tools of SGE.
