Hardware Locality

Hardware Locality solves a key challenge in modern computing: the diversity and complexity of system architectures. It offers a consistent, portable abstraction layer that applications can query to understand the hardware environment. Instead of writing platform-specific code, developers use hwloc's unified API to navigate NUMA nodes, CPU cores, shared caches, and I/O devices. This abstraction empowers runtime systems and libraries to automatically make optimal placement decisions, improving data locality and load balance. It's the smart, vendor-agnostic way to ensure your software performs efficiently everywhere, from a single server to an entire supercomputer.
