Webb30 juni 2024 · The way that Slurm determines how to allocate your jobs to the cluster (i.e. across how many compute nodes, with how many vCPUs, for how long etc) is via Slurm directives that are included at the top of your job script. These directives are indicated by lines starting with #SBATCH. WebbThe following xalloc command (an NCCS wrapper for salloc) sets up X11 forwarding and starts a shell on the job's head node, while the --ntasks argument lets Slurm allocate any number of nodes to the job that together can provide 56 cores: $ xalloc --ntasks=56. The xalloc wrapper forwards all options to salloc.

WebbNodes can have features assigned to them by the Slurm administrator. Users can specify which of these features are required by their job using the constraint option. Only nodes having features matching the job constraints will be used to satisfy the request. WebbThe slurmctld daemon keeps a record of GRES information for all registered nodes, including the number of available resources (for example, the number of GPUs), and the location of each node in a job allocation sequence. When a job or step starts, it specifies GRES allocated to the job.
