Sbatch options
This is a pseudo-best-fit algorithm that minimizes the number of boards and minimizes the number of sockets (within minimum boards) used for the allocation. This default behavior can be overridden specifying a particular "-m" parameter with srun/salloc/sbatch. Without this option, cores will be allocated cyclically across the sockets. CR_LLNThe Slurm page introduces the basics of creating a batch script that is used on the command line with the sbatch command to submit and request a job on the cluster. This page is an extension that goes into a little more detail focusing on the use of the following four options: nodes. ntasks-per-node. cpus-per-task. ntasks.

Options to sbatch that can be given on the command line can also be embedded into the job script as job directives. These are specified one to a line at the top of the job script file, immediately after the #!/bin/bash line, by the string #SBATCH at the start of the line, followed by the option that is to be set. If no file name is specified, sbatch will read in a script from standard input. The batch script may contain options preceded with #SBATCH before any executable commands in the script. sbatch will stop processing further #SBATCH directives once the first non-comment non-whitespace line has been reached in the script.sbatch. The sbatch command is used to submit a job script for later execution. It is the most common way to submit a job to the cluster due to its reusability. Slurm options are usually embedded in a job script prefixed by #SBATCH directives. Slurm options specified as command line options overwrite corresponding options embedded in the job ...
Sequential Steps. First, you need to create a bash script like this: $ cat sample_script.sh #!/bin/bash -l #SBATCH -o std_out #SBATCH -e std_err srun python some_file.py srun sh some_file.sh.
