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!

4S-BACKEND_SETUP(1J)						      4store						      4S-BACKEND_SETUP(1J)

NAME

     4s-backend-setup -- Create a new 4store KB

SYNOPSIS

     4s-backend-setup kbname [--node node-number] [--cluster cluster-size] [--segments segment-count] kb-name

		      --node  Number of this node in the cluster, values range from 0 to cluster-size - 1.  The default is 0.

		      --cluster
			      The number of nodes in the cluster.  The default is 1.

		      --segments
			      The number of segments in the cluster. The default is 2. We recommend one for each CPU core in the cluster as a good
			      starting point. Higher numbers tend to consume more resources, but may result in increased performance.

NOTES

     Once crated with 4s-backend-setup KBs should be started with 4s-backend(1)

SEE ALSO

     4s-query(1), 4s-size(1), 4s-httpd(1), 4s-backend(1), 4s-delete-model(1)

EXAMPLES

     $ 4s-backend-setup --node 0 --cluster 1 --segments 4 demo

     Creates the indexes for a single-machine KB with four segments, named "demo".
