Is there any particular reason you wish to configure this manually? We have a variety of NVidia cards here, and GRES configuration via Qlustar works quite well.
On x86_64 nodes, managed by qlustar, they works also, but those IBM Power nodes are not supported by qlustar, because of different cpu architecture.
I see. slurm.conf does have limited support for GRES, but as far as I know you cannot give any file names there. I am not sure if that would prevent GPU configuration entirely, or if it would just limit Slurm's GPU management (e.g. if Slurm would still be able to give GPUs to jobs, but not tie those to a concrete device).
This leads to a slightly different question (to the list in general): is it possible to exclude Slurm configuration from Qlustar management? We had to do that on an old cluster of ours (with a different management solution) because our SGE config was more involved than what the management software could handle. The vendor advised us to set a certain variable, and we'd manage SGE manually.
