Batch Jobs. The sbatch command is the command most commonly used by RCC users to request computing resources on the Midway cluster. Rather than specify all the options in the command line, users typically write an “sbatch script” that contains all the commands and parameters neccessary to run a program on the cluster.The Slurm controller will set the following variables in the environment of the batch script. SBATCH_MEM_BIND Set to value of the --mem-bind option. SBATCH_MEM_BIND_LIST Set to bit mask used for memory binding. SBATCH_MEM_BIND_PREFER Set to "prefer" if the --mem-bind option includes the prefer option.Jun 29, 2022 · SBATCH directives -- lines beginning with "#SBATCH" -- specify job attributes as well as (sbatch) command line options.
