A cluster means a group of cores that share some resources (e.g. cache) among them under the LLC. For example, ARM64 server chip Kunpeng 920 has 6 or 8 clusters in each NUMA, and each cluster has 4 cores. All clusters share L3 cache data while cores within each cluster share the L2 cache.
Is this different from what we already have with "-smp dies"? Paolo
