[Paraview] pvserver setup for multiple graphics cards on same node

[Moreland, Kenneth]

It just occurred to me that this really should be documented on the ParaView server set up Wiki page.  I added a couple of sections on using multiple GPUs per node and sharing GPUs on nodes.  I added an mpirun command based on our OpenMPI implementation, but I think other implementations use different syntax.  I would appreciate it if other users with experience in using multiple GPUs per node (that includes you, JB) go to the page add suggestions.  (In particular, could someone describe how to do it with MPICH?)

As you will notice from the start of the thread you link to, we use multiple GPUs on a single node (2 for us, but 4 for you).

The secret is to ensure in your case that mpi jobs
0,1 have Display:0
2,3 have Display:1
4,5 have Display:2
6,7 have Display:3

and then all will be well. you'll need a rather complicated mpirun -e blah blah command line.

Hi,

I currently have one linux node with four GPUs and a single 8 core CPU I'd like to setup as a Paraview server. I am unsure how to go about setting things up so that MPI assigns each pair of cores a different GPU, or if problems would arise with the 2 core/1 GPU ratio. Could someone who has experience with this issue give me some pointers regarding the setup?

This thread, for example, seems to imply that I would run multiple instances of pvserver, somehow pointing each to a different GPU?
