Forward Display from compute node
Hello,

sorry if this is an easy thing, but I tried to make it run the whole morning, but it doesn't work so far...

I am logged in on a visualization node of a high performance cluster. On this node I can run several gui-based software for the postprocessing of my cfd-data.

As the visualization node is always very busy, I would like to do the compute nodes the work.
My idea was to submit a bash script where I tell the compute nodes to start the specific software and to forward the display to my local display.

I read out the adress of my display with
Code:
echo $DISPLAY

and tried to start the software on the compute node with the following:

Code:
export DISPLAY="Adress of my display"
"Command for software"

As this did not work, I also tried this:

Code:
ssh -X myusername@server; set $DISPLAY="Adress of my display", "Command for software"

In both cases no X-window opened on my screen.

As I am a noob in unix I would be happy about any advice.

Thanks very much!
