Abstract
A system and method is disclosed for enumerating multi-level processor-memory affinities for non-uniform memory access systems. A processor-memory affinity hierarchy for each possible pairing of a microprocessor and a memory unit in an information-handling system is calculated using at least two characteristics relating to memory-access speed that describe how the microprocessors and memory units are arranged in the information-handling system. The information-handling system then performs an algorithm on each processor-memory affinity hierarchy to obtain processor-memory affinity values in the information-handling system, and populates a table using the processor-memory affinity values. An operating system in the information-handling system can use the table to allocate memory units among microprocessors in the information-handling system.
