To execute your code you need to

build a binary (executable, model code), see Workflow CPU Genoa,
create a slurm job script like in Workflow CPU Genoa, with a slurm partition in table Partition for CPU Genoa,
submit the slurm job script.

> sbatch myjobscipt.slurm
Submitted batch job 8028673
> ls slurm-8028673.out
slurm-8028673.out

There is a single partition that contains all compute nodes.

Partition name	Node count

Partition name	Node count
cpu-genoa	168

Charge rates for the Slurm partitions can be found under Accounting.
