You shouldn't ask for more resources with "srun" than have been allocated with "sbatch" - so if you want the job to be able to use up to 4 cores at once & that amount of memory you'll need to use: sbatch -c 4 --mem=250 --ntasks=1 job.sh I'd also suggest using suffixes for memory to disambiguate the values.
