Resource Accounting Policy
Starting with the 24th open access grant competition, the accounting policy has been changed from normalized core hours (NCH) to node-hours (NH). This means that it is now required to apply for node hours of the specific cluster and node type:
The accounting runs whenever the nodes are allocated via the Slurm workload manager (the sbatch, salloc command),
regardless of whether the nodes are actually used for any calculation.
The same rule applies for unspent reservations.
Resource Accounting Formula
| Resources | NH Consumed |
|---|---|
| Barbora All types, Karolina CPU | allocated nodes * time |
| Karolina GPU | allocated gpus * time / 8 |
| Karolina FAT | allocated cpus * time / 768 |
| Karolina VIZ | allocated cpus * time / 64 |
time: duration of the Slurm job in hours
All other Karolina's partitions (GPU, FAT, VIZ) provide partial node allocation;
i.e.: if you request 4 GPUs on Karolina, you will consume only 0.5 NH \* time.VLQ Resource Accounting
