EMPIRICAL DETERMINATION OF ADAPTER AFFINITY IN HIGH PERFORMANCE COMPUTING (HPC) ENVIRONMENT

摘要

A method, apparatus and program product utilize an empirical approach to determine the locations of one or more IO adapters in an HPC environment. Performance tests may be run using a plurality of candidate mappings that map IO adapters to various locations in the HPC environment, and based upon the results of such testing, speculative adapter affinity information may be generated that assigns one or more IO adapters to one or more locations to optimize adapter affinity performance for subsequently-executed tasks.
