I am able to launch a job on a GPU server the traditional way (using CPU and MEM as consumables):
~ srun -c 1 --mem 1M -w serverGpu1 hostname
serverGpu1
but trying to use the GPUs will give an error:
~ srun -c 1 --mem 1M --gres=gpu:1 hostname
srun: error: Unable to allocate resources: Invalid generic resource (gres) specification
I checked this question but it doesn't help in my case.
