Compared to the original way- partitioning mechanism, we show that the proposed mechanism's performance improved by around 6%, on average.
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Öz Last level caches (LLCs) are part of the last line of defense against the famous memory wall problem.
📊
Key Findings & Data:Here, we propose three enhancements to the existing system: 1) an adaptive traffic threshold mechanism for more portable classification hardware, 2) a new method for classifying way-hungry threads, and finally, 3) a thorough comparison of two design alternatives.
💡
Conclusion & Impact:Compared to the original way- partitioning mechanism, we show that the proposed mechanism's performance improved by around 6%, on average.
Öz Last level caches (LLCs) are part of the last line of defense against the famous memory wall problem. Today, almost all processors utilize a LLC for the same reason. This study extends our previous work, which proposed a cache-partitioning mechanism using thread classification. Here, we propose three enhancements to the existing system: 1) an adaptive traffic threshold mechanism for more portable classification hardware, 2) a new method for classifying way-hungry threads, and finally, 3) a thorough comparison of two design alternatives. Compared to the original way- partitioning mechanism, we show that the proposed mechanism's performance improved by around 6%, on average.
