 # Thread affinity (OpenMP)
-On a laptop or single-socket desktop, every core reaches the same RAM at the same speed. On a multi-socket server, each socket has its own bank of RAM (NUMA, non-uniform memory access): accessing local memory is fast, but crossing the inter-socket interconnect to reach the other socket's RAM costs roughly 2–3× more. By default, the OS is free to migrate threads between cores and sockets, silently moving a thread away from the data it allocated.
