<pre wrap="">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
