[gridengine users] Cannot connect to X server

[Bharanidharan Narayanaswamy]

Yes. I want a window to pop not not in my workstation but in the compute node itself.
Because the application opens a UI (terminal) when the job is triggered. So if the job is able to open the same in the compute node, I'll not get the error.
Is there a possibility to achieve this?
Thanks.

No. Only for interactive jobs started with `qrsh`. You want X11 output for jobs submitted by `qsub` - means: at time the job gets executed there should suddenly a window pop up on your workstation?
