Hardware Locality

Hardware Locality provides a practical set of utilities for binding software processes and threads to specific hardware components based on system topology. It analyzes the architecture's hierarchy—including sockets, cores, caches, and NUMA regions—and offers commands to pin workloads optimally. This control minimizes operating system scheduling overhead, reduces memory access latency, and improves cache utilization. The toolset is essential for tuning high-performance computing applications, ensuring they run efficiently on modern multi-core, multi-socket, and heterogeneous systems by leveraging hardware awareness and locality principles.
