Awesome NUMA

A community-oriented list of libraries, tools, and resources aimed to assist with NUMA-aware software development.

Non-Uniform Memory Access (NUMA) refers to multiprocessor systems whose memory is divided into multiple memory nodes.

Contributing

NUMA library bindings and interfaces

  • libnuma - The libnuma shared library to control NUMA policy for processes or shared memory on Linux
    • numa-rs - Rust bindings for libnuma
    • go-numa - Go bindings for libnuma
    • jnuma - Java bindings for libnuma
    • py-numa - Python bindings for libnuma
    • ocaml-numa - OCAML bindings for libnuma
