Running Multi-threading Jobs

Multi-threading is a type of execution model that allows multiple threads to exist within the context of a process. Simply speaking, a Slurm multi-threading job is a single process, multi-core job. Many applications can belong to this category

  • OpenMP programs,

  • Matlab programs with (Parallel Computing Toolbox) enabled,

  • and so on

An example Slurm Multi-threading job script

#SBATCH --job-name=MyJob
... ...
#SBATCH --ntasks=1
#SBATCH --cpus-per-tasks=8
... ...

This script tells Slurm this is a multi-threading job. It has only 1 process, but that process needs 8 CPU cores to execute.
