Hi Rolandas,
In my cluster I have two exotic IBM Power servers with NVIDIA cards. I succeded install Ubuntu 18.04 and make slurm working qith qlustar 11 server, but for NVIDIA cards to manage I cannot find any way to add manually those resources to global slurm config (gres.conf is managed by qlustar and no way to add something manually).
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.
