The configuration of the Marconi-A2 partition allowed to require different HBM modes (on-package high-bandwidth memory based on the multi-channel dynamic random access memory (MCDRAM) technology) and clustering modes of cache operations:
#SBATCH --constraintsconstraint=flat/cache
Please refer to the official Intel documentation for a description of the different modes.

For flat nodes the jobs can require the KNL high bandwidth memory (HBM) using Slurm's Generic RESource (GRES) options:
#SBATCH --constraintsconstraint=flat
#SBATCH --mem=86000
#SBATCH --gres=hbm:16g
