Numad is a system daemon that monitors NUMA topology and resource usage. It will attempt to locate processes for efficient NUMA locality and affinity, dynamically adjusting to changing system conditions. Numad also provides guidance to assist management applications with initial manual binding of CPU and memory resources for their processes. Note that numad is primarily intended for server consolidation environments, where there might be multiple applications or multiple virtual guests running on the same server system. Numad is most likely to have a positive effect when processes can be localized in a subset of the system's NUMA nodes. If the entire system is dedicated to a large inmemory database application, for example -- especially if memory accesses will likely remain unpredictable -- numad will probably not improve performance.
