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).<BR>
<BR>
The secret is to ensure in your case that mpi jobs <BR>
0,1 have Display:0<BR>
2,3 have Display:1<BR>
4,5 have Display:2<BR>
6,7 have Display:3<BR>
<BR>
and then all will be well. you'll need a rather complicated mpirun -e blah blah command line.<BR>

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