Hello,
I compiled 5.6 superbuild version with EGL and MPI support on my linux machine. I have an instance with 4 GPUs and 24 cores but since I have EGL capabilities, I want to use all 4 GPUs. The following is a command I tried:
`pvbatch --egl-device-index=0,1,2,3 post_scalar_V3.py`
The issue is that upon reviewing the GPU usage, only the GPU with index 0 is being utilized. What’s the correct command to use all the GPUs in my machine? See the nvidia-smi output. As you see at very bottom, only one GPU is being utlized.

Hi @Bruno_Sotelo ,
You need to use MPI for that, and specify different device for each mpi process.
Best,
