Hardware Locality

Unlock the full potential of your hardware with Hardware Locality. This toolset automatically inventories the complex structure of your system, presenting a clear tree of components from processor packages down to individual cores and caches. For performance-sensitive applications, this knowledge is power: it enables precise binding of tasks to the most suitable processing units and memory. By ensuring workloads run on adjacent cores with local cache and memory access, you eliminate unnecessary bottlenecks. Whether you're tuning an MPI job or a custom parallel application, hwloc provides the critical insights needed for optimal performance and portability.
