Code execution
To execute your code you need to
- have a binary, which is the result of code compilation,
- create a slurm job script,
- submit the slurm jobs script.
Submission of a job
blogin> sbatch myjobscipt.slurm Submitted batch job 8028673 blogin> ls slurm-8028673.out slurm-8028673.out
Using mpirun
Using mpirun the pinning is controlled by the MPI library. Pinning by slurm you need to switch off by adding export SLURM_CPU_BIND=none.
