=============================== Numa policy hit/miss statistics =============================== /sys/devices/system/node/node*/numastat All units are pages. Hugepages have separate counters. =============== ============================================================ numa_hit A process wanted to allocate memory from this node, and succeeded. numa_miss A process wanted to allocate memory from another node, but ended up with memory from this node. numa_foreign A process wanted to allocate on this node, but ended up with memory from another one. local_node A process ran on this node and got memory from it. other_node A process ran on this node and got memory from another node. interleave_hit Interleaving wanted to allocate from this node and succeeded. =============== ============================================================ For easier reading you can use the numastat utility from the numactl package (http://oss.sgi.com/projects/libnuma/). Note that it only works well right now on machines with a small number of CPUs.
