Virtualization significantly degrades computational performance on nonuniform memory access (NUMA) systems. The authors propose an optimization scheme based on a memory-access model that covers the entire access path and accommodates the chain-reacting behavior of memory subsystems. A quantitative evaluation shows significant performance improvement with negligible overhead.
