WebDepartment of Computer Science, University of Toronto Web3. Theorem. LFD (longest future distance) is an optimal o ine caching algorithm. 4. Proof. We show that any algorithm can be modi ed to act like LFD without degrading its performance. In particular, let Abe a paging algorithm, and let Sbe a request sequence. Then, for any i= 1;2;:::;jSj, we can construct an o ine algorithm A i that satis es the

WebOn a page fault, we need to choose a page to evict Random: amazingly, this algorithm works pretty well. • FIFO: First-In, First-Out. Throw out the oldest page. Simple to implement, but the OS can easily throw out a page that is being accessed frequently. • MIN: (a.k.a. OPT) Look into the future and throw out the page WebLowest page-fault rate, cannot be implemented in practice, because it requires foretelling the future. is used mostly for comparison with other page-replacement schemes. LRU Page Replacement Least Recently Used, replace the page that has not been used for the longest period of time. implemented on most systems.

WebEach time a requested item is missing from the cache, a cache item must be "evicted" to hold the new item. To determine what item to "evict", we learned the "Farthest-In-Future" algorithm. This algorithm checks the list of future requests and returns which cache item is requested "farthest in the future". This is the item that will be requested ... Web161 future[3].
