Slurm’s core specialization default will change: Slurm --core-spec or -S value will be set to 8. This will provide a symmetric distribution of cores per GCD to the application and will reserve one core per L3 cache region.
RCT should be able to keep this info within resource configuration (as part of system_architecture parameter)
Default strategy for RCT is to disable core specialization (-S 0) - will be done within RP
Slurm provides feature core specialization: https://slurm.schedmd.com/core_spec.html Crusher@OLCF started to reserve 8 cores per node by default (link)
