Errors in using GPU resources in EDEM 2024.1

I am currently working on three simulation files (https://community.altair.com/discussion/39636/analysis-and-optimisation-of-tablet-coating-processes-with-edem?utm_source=community-search&utm_medium=organic-search&utm_term=tablet+coating) given using GPU resources adapted from HPC UGent. However, when I attempt to run the files with the GPU CUDA solver, I encounter the following error: "Can't find selected device."

To resolve this, I tried loading the CUDA module via the command line using:

$ module load CUDA/12.6.0

nvidia-smi error 1.png

Unfortunately, this did not work.

Could you suggest a solution to fix this issue?

    Hi,

    The error message in the print you shared suggested clicking on Tools > Simulator Engine > CUDA > Device Start Test.

    Have you tried that? If so, what was the result of the test?

    Regards,

    Sorry for the late response. This is what I have got after following the GPU device testing. It seems successful but I still get the same result: can't find the selected GPU device. Also, I cannot increase the number of GPU devices from 0.

    I think the reason is that after loading GPU CUDA module, I need to start the software by vglrun command, but I'm getting an error as shown above: permission denied. Do you have any suggestion for this?
