[Paraview] Multiple GPUs per node

[srikanth.nagella at stfc.ac.uk]

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
