Abstract :Last level caches insert ignore into journalissuearticles values(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.
