Using the different parts of Kebnekaise

Since Kebnekaise consists of several different node types using them correctly takes a bit of getting used to.

Slurm GPU Resources (Kebnekaise)

We have two types of GPU cards available on Kebnekaise, NVIDIA Tesla K80 (Kepler) and NVIDIA Tesla V100 (Volta).

To request GPU resources one has to include a GRES in the submit file. The general format is:

#SBATCH --gres=gpu:<type-of-card>:x

where <type-of-card> is either k80 or v100 and x = 1, 2, or 4 (4 only for the K80 type).

The K80 enabled nodes contain either two or four K80 cards, each K80 card contains two gpu engines.
