Hi 平田邦生/Kunio, (It's after mid-night in Japan! Hope you can get some sleep soon after this SGE setup.)
There are 2 ports needed when you setup SGE. The first one is the qmaster port, and the second one is the execd port. But qsub itself does not listen to a port, it opens a socket connection and connects to the qmaster via the qmaster port. And X forwarding via SSH requires more setup on the execution side, which SGE itself is not doing. Also, if DISPLAY is set to "localhost:11.0", then it will not work, as localhost resolves to the hostname of execution host, and on the execution host you don't have sshd running in X forwarding mode. The easiest way to get X forwarding with SGE is to use the qrsh+SSH integration (already mentioned by Rayson), or you will need to setup X and let other machines in your cluster open the X display on your own workstation: http://tldp.org/HOWTO/Remote-X-Apps-6.html -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: "Ron Chen" <[email protected]> > Cc: [email protected] > Date: Wednesday, April 6, 2011, 2:32 AM > Hi Ron, > > thank you for your message. > > > From SGE point of view, it just executes the batch > job, and SSH X tunneling is something that SGE itself does > not know. > > Before submitting the e-mail to this mailing-list, I > thought that a > special setting for the port used in > 'qsub' of SGE was required. > My understanding is that this kind of setting in Linux is > not required > for my aim. > > Is it okay?
