+== [=#SampleParaViewSessionJURECAComputeNodes] Starting a pvserver on JURECA's compute nodes
 
+In this section we show how to use ParaView's server side rendering capabilities on JURECA's '''compute nodes''' in a sample session step by step.
+1. Open a terminal and load the modules providing the ParaView software
+{{{
+bash-4.2$ module load Stages/Current intel-para ParaView/5.0.1-OSMesa
+}}}
 
+2. Next, we allocate some resources for our ParaView server, and run the ParaView server (in this example session on 1 node, using 24 tasks)
+{{{
+bash-4.2$ salloc --partition=devel --nodes=1 --time=00:20:00
+salloc: Pending job allocation 1711109
+salloc: job 1711109 queued and waiting for resources
+salloc: job 1711109 has been allocated resources
+salloc: Granted job allocation 1711109
+bash-4.2$ srun --nodes=1 --ntasks=24 pvserver
+}}}
+
+ which will produce the following output from the ParaView server:
+{{{
+Waiting for client...
+Connection URL: cs://jrc0036:11111
+Accepting connection(s): jrc0036:11111
+}}}
+ where 
+{{{
+jrc0036:11111 
+}}}
+ is the hostname and portnumber on JURECA the server will listen to.
+3. As a next step, click the Connect button in the ParaView GUI and configure a server with the corresponding hostname and portnumber as described [wiki:SampleParaViewSessionJURECA#connectToServer here]

+1. open a terminal and load the modules providing the ParaView software
+{{{
+bash-4.2$ module load Stages/Current intel-para ParaView
+}}}
+and set the DISPLAY environment variable as follows
+{{{
+bash-4.2$ export DISPLAY=:0.0
+}}}
+2. Next, we allocate some resources for our ParaView server (this step has to be omitted in case you started a VNC session on the visualization batch nodes via strudel, since strudel allready allocated some resources for you)
+{{{
+bash-4.2$ salloc -N 2 -p vis --gres gpu:2 --start-xserver     
+}}}
+ and run the ParaView server (in this example session on 2 nodes, using 48 tasks): 
+{{{
+bash-4.2$ srun --cpu_bind=none --ntasks=48 --gres=gpu:0 vglrun pvserver --use-offscreen-rendering
+}}}
