A load from a page attached to the processor running a thread can take a shorter route than a load from memory attached to another processor package or NUMA node.</p> <p>This arrangement is called <strong>non-uniform memory access</strong>, or NUMA. It lets systems scale memory capacity and bandwidth across multiple processor sockets or chiplet groups without forcing every memory request through one centralized controller.</p>
