<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>That’s basically what Utkarsh meant by needing to set up the environment correctly. Typically the GPU used is determined by the DISPLAY environment variable. “:0” is typically the first GPU and “:1” is typically the second GPU. You need to launch pvserver such that node 0 gets :0 for the DISPLAY env variable (or –display flag) and node 1 gets :1.<BR>

<BR>
Thanks for the response.<BR>
The suggested command line creates two seperate processes and devides the data properly, but I'm getting both the tiles in the same display(connected to first GPU).<BR>

Yes, just run pvserver as follows:<BR>
<BR>
mpirun -np 2 pvserver -tdx=2<BR>
<BR>
Of course, you'll have to build your own MPI enabled ParaView (you<BR>
cannot use the binaries provided by on www.paraview.org <<a href="http://www.paraview.org">http://www.paraview.org</a>> ). You'll have<BR>
to ensure that the environment is set up correctly so that each<BR>
pvserver processes gets the right display etc.<BR>

Hi,<BR>
<BR>
Is it possible to achieve tiled display using a single dual-gpu machine<BR>
which can drive 4 displays? I have read that the number of servers should<BR>
atleast be equal to number of tiles.<BR>
Can paraview be configued to have atleast a 2x1 tiled display with 2 GPUs?<BR>
<BR>
Thanks<BR>
