Experience with Intel PIN ... WebHowever, temporal locality exploited by the cache is a function of both the replacement policy and the size of the working set relative to the available cache size. For example, if a workload frequently reuses a working set of 2 MB, and the available cache size is 1MB, then the LRU policy will cause all the installed lines to have poor temporal ...

WebJun 19, 2024 · Cache Replacement Policies. This book summarizes the landscape of cache replacement policies for CPU data caches. The emphasis is on algorithmic issues, so the authors start by defining a taxonomy that places previous policies into two broad categories, which they refer to as coarse-grained and fine-grained policies. WebOne popular replacement policy, "least recently used" (LRU), replaces the oldest entry, the entry that was accessed less recently than any other entry (see cache algorithm). More efficient caching algorithms compute the use-hit frequency against the size of the stored contents, as well as the latencies and throughputs for both the cache and the ...
