It includes the `numactl` command, libnuma, and utilities such as `numastat` and `memhog`. ### Project history numactl grew out of early Linux 2.6 NUMA policy work. LWN published Andi Kleen's January 2004 announcement of a Linux 2.6 NUMA policy API implementation consisting of kernel policy API support, libnuma for applications, the `numactl` user-space policy tool, and test programs. The current GitHub README keeps the same project definition: simple NUMA policy support, with a `numactl` program to run other programs under a specific NUMA policy and a libnuma shared library for applications. The README also states that the libnuma binary interface is intended to stay binary compatible, with incompatible changes using new symbol versions. ### Adoption history numactl became part of the normal Linux performance and systems toolbox because multi-socket and large-memory machines make memory locality observable. Linux man-pages document it as the command for running processes with specific NUMA scheduling or memory placement policy, inherited by child processes, and for setting persistent policy on shared memory segments or files. Distribution adoption is broad. The av.db source record maps numactl/libnuma packages across Alpine, Debian, Fedora, Nix, Arch, Ubuntu, and openSUSE; Homebrew packages it for Linux bottles and showed stable 2.0.19 with 28,653 installs over the visible 365-day analytics window on July 1, 2026. ### How it is used Typical practical commands include `numactl --hardware` to inspect NUMA topology, `numactl --cpunodebind` or `--physcpubind` to bind CPU execution, `--membind` or `--preferred` to steer memory allocation, and `--interleave` to distribute pages across nodes. `numastat` is used to inspect allocation behavior after a workload runs. Package nerds and performance engineers use numactl when benchmarking databases, JVMs, scientific workloads, ML training/inference processes, or any memory-bandwidth-sensitive service where scheduler placement and page locality can change results. The lazy but correct rule is to measure: pinning can help controlled benchmarks and production isolation, but bad bindings can make performance worse. ### Why package nerds care numactl is a small package with outsized systems significance. It exposes Linux NUMA policy to shell users and gives C/C++ programs libnuma, making it one of the common bridges between kernel memory policy and practical performance tuning. ### Timeline - 2004-01: LWN carried Andi Kleen's announcement of libnuma/numactl and the Linux 2.6 NUMA policy API implementation. -
