Slurm script for running EGSnrc user codes as a job array

egsnrc_slurm_job_array.sh

#!/bin/bash
# SLURM_ARRAY_TASK_ID will range from 1 to 10
#SBATCH --array=1-10
# adjust time limits as needed
#SBATCH --time=02:00:00
# run the user code using the input.egsinp file on ten cores
# note: * each run will use a different set of initial random numbers
#       * the -s flag forces EGSnrc to use a simple job control object (no locking)
user_code -i input.egsinp -p pegs_data.pegs4dat -b -P 10 -j $SLURM_ARRAY_TASK_ID -s
# this will result in 10 egsdat files, which must be combined manually afterwards 
# using calculation=combine in the input file.
