[slurm-users] Question about memory allocation

[Kraus, Sebastian]

Hi Mahmood,


>> will it reserve (looks for) 200GB of memory for the job? Or this is the hard limit of the memory required by job?


No, this indicates the amount of residual/real memory as reqeusted per node. Your job will be only runnable on nodes that offer at least 200 GB main memory (sum of memory on all sockets/cpu of the node). Please also have a closer look at man sbatch.

Best
Sebastian

Subject: [slurm-users] Question about memory allocation

Hi,
If I write

#SBATCH --mem=10GB
#SBATCH --nodes=4
#SBATCH --ntasks-per-node=5

will it reserve (looks for) 200GB of memory for the job? Or this is the hard limit of the memory required by job?

Regards,
Mahmood
