Comsol 6.4 on Linux w/ multiple GPUs

Please login with a confirmed email address before reporting spam

Hi,

I've recently been trying to make Comsol use multiple GPUs on a Linux-based supercomputer. Both CPU-only and single GPU configurations work fine.

The machine has 4 GPUs, and given the same CUDA-related variable values, Python manages to use all 4 while Comsol only uses 1. My study uses the cuDSS solver, and I've ticked the option to use multiple GPUs in the solver config menu, to no avail...

Anyone facing the same issue or having thoughts on the matter ?

Cheers
