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

[Moreland, Kenneth]

It sounds like Dave is volunteering to add the machines.pvx method to the Wiki page.  I personally don't even know how to set up a normal client/server connection with it.  It is not documented in the book.

An alternative to making a complex mpirun arguments is to supply a machines.pvx file. That will let you assign displays to each process on the server. See the ParaView guide p134. for details.

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?

Thanks,
