Code execution

To execute your code you need to

1. build a binary (executable, model code), see Workflow OpenMPI CPU Genoa,

2. create a slurm job script like in Workflow OpenMPI CPU Genoa, with a slurm partition in table Partition for CPU Genoa,

3. submit the slurm job script.

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

Partition for CPU Genoa

There is a single partition that contains all compute nodes:
