btw, here is an batch script
<https://github.com/burlen/pvserver-configs/blob/master/servers/nautilus/3.10.0-x/start_pvserver-x.qsub>
starting ParaView with pvservers assigned to GPU's round robin, from the
SGI UV 1000 with 8 GPU. The other tricky aspect of running PV on
multiple GPU is configuring X11. Here is the xorg.conf
<https://github.com/burlen/pvserver-configs/blob/master/servers/nautilus/3.10.0-x/xorg.conf>
on this system, each card has it's own device, screen, and layout.
Hope it helps.

Hi John,
You need to run 4 X servers, one X server per GPU card.

Subject: [Paraview] Multiple GPUs per node
I am trying to take advantage of all four GPUs on a 32 node Amazon ec2 cluster.
However, I seem to only be able to utilize the first GPU.
I run pvserver as follows:
1) Manually start an X display with the command : sudo X :0 &
2) run pvserver with the following command (using OpenMPI's mpirun):
mpirun -np 16 pvserver -display :0.0 : -np 16 pvserver -display :0.1
When I try to connect the client, I get an error saying that the client could
not connect to the remote display. Everything works fine using display :0.0
only.
Does anyone know what I might be doing wrong here? Thank you for your time!
John
