[Paraview] client/server error for large superquadrics

Tue Jun 12 09:31:49 EDT 2007

It looks like your server is crashing because it is trying to open a
connection to the local X host and is failing.  You should be able to
correct this by either opening up the X host to the mpi job or compiling
with OSMesa (in which case the -use-offscreen-rendering will prevent a
connection any X host).

On a larger issue, ParaView 2 was able to correctly detect this, give a
warning to the user at the client, and perform all rendering locally on
the client.  Has this functionality gone away with ParaView 3?  If so,
we need to bring it back.

Subject: [Paraview] client/server error for large superquadrics

I am experiencing a problem with Paraview 3.0.1 when generating large
i.e. 1024x1024 Superquadric sources when testing client/server mode.
Smaller values e.g. 1024x16 or 128x128 for example work ok. Large values
i.e. 1024x1024 in local mode work ok. I have installed the repository
version of PV3 and MPICH-1.2.7 and everything appeared to installed
correctly. I have tried it with and without offscreen rendering. Clients
and servers have the foillowing configuration, SUN Ultra 40, AMD
Opteron, SLED10.1 with NVIDIA Quadro FX 3450 GPU with the latest NVIDIA
drivers

Does anyone have any ideas why this is happening?

Regards

Wayne
