- If you do not specify the walltime (by means of the #SBATCH --time directive), a default value of 30 minutes will be assumed.
- If you do not specify the number of cores (by means of the "SBATCH -n" directive) a default value of 36 will be assumed.
- If you do not specify the amount of memory (as the value of the "SBATCH --mem" DIRECTIVE), a default value of 3000MB will be assumed.
- Even though you can ask up to 123000MB, we strongly suggest to limit the amount of the requested The maximim memory per node to 118000MB to avoid memory swapping to disk with serious performance degradationis 118000MB.
The special partition is designed for not-ordinary types of jobs, and users need to be enabled in order to use it. Please write to superc@cineca.it in case you think you need to use it.
...
The maximum memory which can be requested is 90 GB 86000MB for cache nodes. However, to avoid memory swapping to disk with the associated performance degradation we strongly suggest to use up to 86 GB for cache nodes.
For example, to request a single KNL node in a production queue the following SLURM job script can be used:
...
The maximum memory which can be requested is 180 GB 182000MB and this value guarantees that no memory swapping will occur.
