The explanation of this method will be completed in the following sections where a very useful code (hello_jobstep
) will be used to confirm optimal (or sub-optimal, or incorrect) binding of GCDs (Slurm GPUs) and chiplets for srun
job steps. Other examples of its use are already listed in the table in the subsection above and its use in full scripts will be provided at the end of this page.
