Webtime on eviction CLOCK The CLOCK policy is an approximation of LRU without needing a separate timestamp per page. In the CLOCK policy, each page is given a reference bit. When a page is accessed, set to 1. To visualize this, organize the pages in a circular buffer with a “clock hand”. Upon sweeping check if a page’s bit is set to 1.
In computing, cache algorithms (also frequently called cache replacement algorithms or cache replacement policies) are optimizing instructions, or algorithms, that a computer program or a hardware-maintained structure can utilize in order to manage a cache of information stored on the computer. … See more The average memory reference time is $${\displaystyle T=m\times T_{m}+T_{h}+E}$$ where $${\displaystyle m}$$ = miss ratio = 1 - (hit ratio) See more Bélády's algorithm The most efficient caching algorithm would be to always discard the information that will not be needed for the longest time in the future. This optimal result is referred to as Bélády's optimal algorithm/simply optimal … See more • Cache-oblivious algorithm • Locality of reference • Distributed cache See more One may want to establish, through static analysis, which accesses are cache hits or misses, for instance to rigorously bound the worst-case execution time of a program.

WebI have developed a testing framework to evaluate di erent eviction strategies under a cache simulation by using the real world pre-cache access records. The framework also replays post-cache accesses on a real solid state disk to get a more realistic measurement of the performance. I have compared the 2Q, ARC, BRRIP, CAR, CLOCK, CLOCKPRO, LRU,
