Add possibility to assign cores from the same CCX in AMD CPUs to make use of the same L3 cache.
With a specific 2-core workload we noticed significant performance improvements of about 50% in shorter runtime when both cores reside on the same L3 cache group (CCX) of an AMD EPYC CPU. Therefore it would be very beneficial to be able to have LSF select or prioritize cores from the same L3 cache group, not just on the same NUMA node.
However, as different workloads might benefit from the opposite case (i.e. larger L3 cache) also the counterpart might be useful.
