New hardware available on Kebnekaise including new GPUs
There are three new nodes available on Kebnekaise.
Two of the new nodes have dual NVIDIA A100 GPUs and one is a many-core CPU node.
There are some notable differences with these nodes.

Since Kebnekaise consists of several different node types using them correctly takes a bit of getting used to.
NOTE: your project need to have time on the GPU nodes to use them, as they are considered a separate resource now. To use them you use the SLURM command mentioned below. For V100s there is no specific partition you need to give, but there is for the A100s - see below.
We have two types of GPU cards available on Kebnekaise, NVIDIA Tesla V100 (Volta) and NVIDIA A100 (Ampere).
To request GPU resources one has to include a GRES in the submit file. The general format is:
[ Details: Compute (Skylake-SP) nodes | Compute nodes (AMD Zen3) | Largemem nodes | GPU nodes (V100) | GPU nodes (A100) ]
Kebnekaise is the latest supercomputer at HPC2N. It is named after the massif of the same name, which has some of Sweden's highest mountain peaks (Sydtoppen and Nordtoppen). Just as the massif, the supercomputer Kebnekaise is a system with many faces.
