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) | Compute nodes (AMD Zen4) | Largemem nodes | GPU nodes (V100) ]
[ GPU nodes (A100) | GPU nodes (A40) | GPU nodes (MI100 AMD) | GPU nodes (A6000) | GPU nodes (L40s) | GPU nodes (H100) | GPU nodes (A40) ]
