Abstract

In this paper, we augment traditional cache partitioning with thread-aware adaptive insertion and promotion policies to manage shared L2 caches. The proposed mechanism can mitigate destructive inter-thread interference, and meanwhile retain some fraction of the working set in the cache, therefore results in better performance.
