[Paraview] VirtualGL/TurboVNC and multi-GPU - using only one GPU?

[Paul McIntosh]

Hi, sorry that should read  "I only see 1 of 2 GPU's getting used" i.e. I
have 2 GPU's and the second is ignored. Also I tested glxgears running
through VirtualGL and I can point it to either one or the other GPU and that
works. So it seems to be something with pvserver launched from a process
that uses VirtualGL.

Cheers,

Paul

Hi,

Is any one out there using ParaView client through VirtualGL and using the
default_server config?

I notice that if I launch the command below from within ParaView I only see
1 or 2 GPU's getting used (looking at load). If I run it outside of ParaView
then both GPU's have load. I am running ParaView client through VirtualGL,
and "glxinfo -display :0" (called from ParaView) sees both GPUs on the node 

mpirun -v -hostfile $PBS_NODEFILE -bynode -np 6
/usr/local/$APPLICATION/$VERSION/bin/pvserver --server-port=11112 -display
:0.1 : -np 6 /usr/local/$APPLICATION/$VERSION/bin/pvserver -display :0.0

This is both a heads up and a question - obviously I see much faster
rendering when both GPUs are used ;)

Cheers,

Paul
