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.

Hi Rakesh,
It sounds as though the compute node cannot see your workstation
across the network. This is a common situation.
for debugging the issue see if you could follow these steps:
http://paraview.org/Wiki/Reverse_connection_and_port_forwarding#A_Forward_Connection_Over_an_ssh_Tunnel
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.

Hi,
I am trying to get ParaView-3.12.0 working on our visualisation
cluster. However I am getting errors such as the following
"Socket error in call to conect : Connection refused"
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.
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.
I did get it to work by using a machinefile (ie outside slurm) and it
worked in client-server to my work station.
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).
Can some one please give me some hints how I can debug this further?
Any pointers are greately appreciated.
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?
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?
Regards,
Rakesh
