This Open Source and simple command-line utility adds NUMA policy support to Linux
The NUMA (Non-Uniform Memory Access) policy allows you to tune programs by controlling the placement of memory in NUMA systems.
The NUMA system is comprised of multiple nodes of processors and/or memory, which are linked together by a special high-speed network.
The numactl software is designed to run other applications with a specific NUMA policy, and the NUMA API (libnuma) can be used to set NUMA policy in the respective apps.
numactl also includes various utilities, such as numastat, which can be used to decode the kernel NUMA statistics.
