# Awesome NUMA

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



[Non-Uniform Memory Access (NUMA)](https://en.wikipedia.org/wiki/Non-uniform_memory_access) refers to multiprocessor systems whose memory is divided into multiple memory nodes.
