Patches for the Linux kernel over the past week are preparing for an SNC6 sub-NUMA clustering mode. This is the first time I’ve seen patches or mentions of an SNC6 mode compared to SNC 1/2/3/4 modes with existing processors.
Sub-NUMA Clustering with Intel Xeon CPUs allows for each compute die to be exposed as its own NUMA domain. SNC3 with Granite Rapids can help some workloads compared to the HEX mode.
