For example, 
Minimum memory required per allocated CPU. If you request 24 cores (one node) you will get 120gb of memory on both standard node and on high-memory node. 

If you specify the real memory required per node: 
--mem = 120gb 

You will get the same. 

However, if you specify 
#SBATCH --exclusive 
#SBATCH -C mem768 
#SBATCH --mem = 700gb

You will get 700 gb on high memory node. 


Job Arrays

Multiple copies of a job can be submitted by using a job array. The --array option can be used to specify the job indexes Slurm should apply.


"Batch job submission failed: Invalid job array specification".

The environment variable $SLURM_ARRAY_TASK_ID indicates the index of the array element (i.e. job) in the job array, and is accessible from within that job.
