In this work we study the effect of data locality on the performance of Gaussian 03 code running on a multicore Non-Uniform Memory Access (NUMA) system. A userspace protocol which affects runtime data locality, through the use of dynamic page migration and interleaving techniques, is considered. Using this protocol results in a significant performance improvement. Results for parallel Gaussian 03 using up to 16 threads are presented. The overhead of page migration and effect of dual-core contention are also examined
