摘要：
In this work we discuss the performance problems of nested OpenMP programs concerning thread and data locality particularly on cc-NUMA architectures. We provide a user friendly solution and demonstrate its benefits by comparing the performance of some kernel benchmarks and sonic real-world applications with and without applying our affinity optimizations.
