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.<br><br clear="all">David E DeMarle<br>

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>

<blockquote type="cite"><div><div></div><div class="h5">Hi,<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>
