LIKWID and SLURM

LIKWID and SLURM

When running jobs on a HPC system, it is nowadays commonly managed through the job scheduler SLURM. If you want access to the performance monitoring features of your system, some cluster-specific flags might be required when submitting a job. When a job is started, it is commonly restricted to the requested resources which might interfere with the execution of LIKWID (and other tools). This page contains some helpful hints for users as well as configuration ideas for administrators.
