Code execution

After creation of

• a binary (executable, model code) like in Workflow CPU CLX,
• a slurm job script like in Workflow CPU CLXwith a slurm partition in table Partition for CPU CLX,

submit the slurm job script to execute the binary on compute nodes.

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

Partition for CPU CLX

The compute nodes of the CPU cluster of system Lise are organised via the following slurm Slurm partitions.

See Slurm usage how to pass the 12h walltime wall time limit with job dependencies.

Which partition to choose?

If you do not request a partition, your job will be placed in the default partition, which is standard96.

The default partitions are The default partition cpu-clx is suitable for most calculations. The :test partitions are, as the name suggests, intended for shorter and smaller test runs. These have a higher priority and a few dedicated nodes, but are limited in time and number of nodesprovide only limited resources. Shared nodes are suitable for pre- and postprocessingpost-processing. A job running on a shared node is only accounted for its core fraction (cores of job / all cores per node). All non-shared nodes are exclusive to one job only at a time.

The available home/local-ssd/work/perm storages file systems are discussed in Storage under File Systems.

An For an overview of all Slurm partitions and node statuses is provided bystatus of nodes: sinfo -r
To see For detailed information about a particular nodes type: scontrol show node <nodename>

Charge rates for accounting

Charge rates for the slurm partitions you find in Slurm partitions can be found under Accounting.
