[Paraview] cluster: works with -np 1, crashes when runs in parallel :-(

[Stéphane Backaert]

Hello,

I have installed paraview version 3.12.0-RC3-23-g712c45e on a cluster: compiled with intel compiler, openmpi-1.5.3, no hardware acc. so Mesa-7.9 and --use-offscreen-rendering flag at startup, MPI set to ON in ccmake. 

I launch the server with mpirun -np x ./pvserver  --use-offscreen-rendering and, through an ssh connection, the client on my laptop (latest version too).  That works fine :-) ... but slow :-(. 
So I try to use more procs, for example, mpirun -np 2 ./pvserver  --use-offscreen-rendering. There are two processes running on the cluster (I see them with 'ps x' command).

My problem: when I connect my client to this server, the connection is etablished but the server crashed immediately with the message:

Waiting for client
Connection URL: cs://localhost:11111
Client connected.

I tried with different configuration options in ccmake related to MPI, no changes. The cluster works for other MPI programs...

Any idea?

Thanks!
