[Paraview] [EXTERNAL] pvserver on multiple nodes

[Scott, W Alan]

We do a reverse connect.  Thus, the server is connecting to the client.  For us, start the client, which will hang waiting for the server.  Start all of the servers, reverse connect, passing it the name of the client machine.  The specific commands are in the docs I mentioned.

Sort of like this:
In directory lib/paraview-4.1, create a file named default_servers.pvsc.  Put in it:

<Servers>
<Server name="Manual-Script" owner="user" resource="csrc://localhost" >
<ManualStartup/>
</Server>

</Servers>


paraview --server=Manual-Script --connect-id=123 &
(get your nodes, run pvserver on your nodes) .../pvserver --use-offscrean-rendering -rc -ch=client-machine-name -connect-id=123

We don't change ports, but there is a command in ParaView to change ports.  Normally, ParaView connects on 11111 by default.

Hello Scott,

Thanks for the reference. It answers my question that Paraview communicates with rank 0 only. So if a paraview job gets spawned on multiple nodes, and rank zero gets allocated to cn01 say, so I connect the client to server cn01:11112?

Thanks again,
Wadud.

I believe you are looking for the section in the ParaView wiki that is called Server Setup.  There are multiple pages here, dealing with server setup, client setup, port forwarding, etc.  http://www.paraview.org/Wiki/ParaView#Server_Setup

Hello,

How do I configure the client when pvserver runs on multiple nodes via mpirun? e.g. cn01, cn02, cn03 and cn04. There is a flag --multi-servers for paraview but no documentation on it. Any help will be greatly appreciated.

Regards,
