Quantifying the performance and energy efficiency of advanced cache indexing for GPGPU computing

摘要

To achieve higher performance and energy efficiency, GPGPU architectures have recently begun to employ hardware caches. Adding caches to GPGPUs, however, does not always guarantee improved performance and energy efficiency due to the thrashing in small caches shared by thousands of threads. While prior work has proposed warp-scheduling and cache-bypassing techniques to address this issue, relatively little work has been done in the context of advanced cache indexing (ACI).
