The slow progress in memory access latencies in comparison to CPU speeds has resulted in memory accesses dominating code performance. While architectural enhancements have benefited applications with data locality and sequential access, random memory access still remains a cause for concern. Several benchmarks have been proposed to evaluate the random memory access performance on multicore architectures. However, the performance evaluation models used by the existing benchmarks do not fully capture the varying types of random access behavior arising in practical applications.
