[Paraview] Tiled display with multi-gpu.

[Moreland, Kenneth]

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.

Hi Utkarsh,

Thanks for the response.
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).

Yes, just run pvserver as follows:

mpirun -np 2 pvserver -tdx=2

Of course, you'll have to build your own MPI enabled ParaView (you
cannot use the binaries provided by on www.paraview.org <http://www.paraview.org> ). You'll have
to ensure that the environment is set up correctly so that each
pvserver processes gets the right display etc.

Hi,

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

Thanks
