[slurm-users] Building Slurm RPMs with NVIDIA GPU support?

[Tina Friedrich]

Yeah, I don't build against NVML either at the moment (it's filed under 
'try when you've got some spare time'). I'm pretty much 'autodetecting' 
what my gres.conf file needs to look like on nodes via my config 
management, and that all seems to work just fine.

CUDA_VISIBLE_DEVIZES and cgroup device restrictions works, as well.
