[Paraview-developers] Paraview server in MultiGPU environment

[Khayam Gondal]

Hi.
I have two NVIDIA K40m GPUs installed on server (48 CPU cores). I have
compiled and installed Paraview server with MPI support and using NVIDIA
Drivers.

I use following command to start pvserver

mpirun -bynode -np 24 bin/pvserver --disable-xdisplay-test
--egl-device-index=1 : -np 24 bin/pvserver --disable-xdisplay-test
--egl-device-index=0

But I don't now how to check that pvserver is actually using *both *of the
GPUs not just one.. Actually If I change the --egl-device-index value to a
random number like 8 or 9, server still starts up and client got connected
to it.

it using both GPUs or just one?)
