Hi Kunio, So you are saying that only SGE is upgraded and then X forwarding does not work?
From the error messages, I believe it has to do with something else, as the X client is trying to open the display at "localhost:11.0" on the execution host! From SGE point of view, it just executes the batch job, and SSH X tunneling is something that SGE itself does not know. -Ron --- On Wed, 4/6/11, 平田邦生 <[email protected]> wrote: > From: 平田邦生 <[email protected]> > Subject: Re: [gridengine users] Using X-window program failed > To: [email protected] > Date: Wednesday, April 6, 2011, 1:33 AM > Dear Rayson Ho, > > thank you for your quick response. > But the problem is that 'qsh' does not work... > In the normal case, after typing "qsh" at a qmaster, a > 'xterm' appears > on an userpc01. > But in the yamac01 case, this does not appear. > > Added to this, I can run X-window program via 'qsub -v > DISPLAY=$DISPLAY' command on > OS: Vine Linux, SGE: older version. > > The upgraded SGE, a current version, lost the function? > (this means a upgrade is more 'secure'???) > > Sincerely, > > Kunio HIrata > > > 2011/4/6 Rayson Ho <[email protected]>: > > qsub submits a normal batch job, and from a quick > "grep" of the > > source, only when the job is submitted via qsh, the > execution side > > does the DISPLAY variable handling. > > > > You may want to try qsh: > > qsh - > submit an interactive X-windows session > to Sun > > > Grid Engine. > > > > http://gridscheduler.sourceforge.net/htmlman/htmlman1/qsh.html > > > > And if ssh X forwarding is needed in your setup, try > this: > > http://gridscheduler.sourceforge.net/howto/qrsh_qlogin_ssh.html > > > > Rayson > > > > > > > > On Tue, Apr 5, 2011 at 12:36 PM, 平田邦生 <[email protected]> > wrote: > >> 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.
