NUMA only applies when different parts of CPUs cannot access memory uniformly. Even for MCM Ryzen / Threadripper CPUs, their cores perfrom memory access unifromly through the only IO die. Also, the flag -XX:+UseNUMA forces enabling NUMA. In general, this flag shouldn't be needed since with this flag absent JVM will automatically detect whether NUMA is needed.
