although, I guess that's not really consistent with your 3.10
install working... all the same you may find that the attached
scripts help. Sorry for not reading your post closer the first time.<br>

Hi Rakesh,<br>
<br>
It sounds as though the compute node cannot see your workstation
across the network. This is a common situation. <br>
<br>
for debugging the issue see if you could follow these steps:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://paraview.org/Wiki/Reverse_connection_and_port_forwarding#A_Forward_Connection_Over_an_ssh_Tunnel">http://paraview.org/Wiki/Reverse_connection_and_port_forwarding#A_Forward_Connection_Over_an_ssh_Tunnel</a><br>
<br>
If that works you probably would like to automate the process
using a ParaView client side pvsc script to establish a reverse
ssh tunnel to the cluster's login node, which is presumably
visible from the compute nodes, and then tell the pv server to
connect to this tunnel in a server side startup script, which
submits a batch job using a batch script. I'm attaching an example
from NERSC's Cray called franklin, take a look and see if it
helps.<br>

<div>Hi,</div>
<div> </div>
<div>I am trying to get ParaView-3.12.0 working on our
visualisation cluster. However I am getting errors such as
the following</div>
<div> </div>
<div>"Socket error in call to conect : Connection refused"</div>
<div> </div>
<div>As a bit of a background, I have ParaView-3.10.1 working in
client-server mode on the same cluster. On the server, we have
IntelMPI-4.0.1 and Slurm as the scheduler.</div>
<div> </div>
<div>I tried debugging the problem by printing stuff out in
vtkSocket.cxx file - I always get the message which says
"Connected" from slurm out file. The ParaView-3.12.0 client
then just hangs.</div>
<div> </div>
<div>I did get it to work by using a machinefile (ie outside
slurm) and it worked in client-server to my work station.</div>
<div> </div>
<div>I am not really sure what is the cause of this - my
suspicion is that this either to do with IntelMPI-4.0.1 and
ParaView-3.12.0 or with Slurm-2.1.4 (which is what is
available on the cluster).</div>
<div> </div>
<div>Can some one please give me some hints how I can debug this
further?</div>
<div> </div>
<div> </div>
<div>Any pointers are greately appreciated.</div>
<div> </div>
<div>Given my level of desperation, I tried with
Paraview-3.14.0-RC2 and things have really changed here - for
example, what happend to the PV_CLIENT_HOST variable? Is this
no longer set? </div>
<div>I also note that when you set up a profile to connect to
the server in reverse-connection mode, it no longer allows you
to specifiy host name - is this intentional?</div>
<div> </div>
<div>Regards,</div>
<div>Rakesh</div>
