Intel Fixing Up Sub-NUMA Clustering For Linux So That It Behaves With RDT

Sub-NUMA Clustering with Intel Xeon processors allows for splitting up the CPU cores, cache, and memory into multiple NUMA domains for enhancing the performance of NUMA-aware applications. While SNC can help in a number of cases especially plenty of HPC and server workloads, currently it's not properly supported if making use of Resource Director Technology (RDT) on modern Intel CPUs. That is in the process of changing with new Linux kernel patches being worked on by Intel...
