A Comparison of Page Replacement Algorithms

Amit S. Chavan, Kartik R. Nayak, Keval D. Vora, Manish D. Purohit, Pramila M. Chawan
2011 International Journal of Engineering and Technology  
We look at the traditional algorithms such as LRU and CLOCK, and also study the recent approaches such as LIRS, CLOCK-Pro, ARC, and CAR.  ...  A virtual memory system needs efficient page replacement algorithms to decide which pages to evict from memory in case of a page fault.  ...  Reuse distance, which is analogous to IRR of LIRS, is an important parameter for page replacement decision in CLOCK-Pro [4] .  ...

Ex-Tmem: Extending Transcendent Memory with Non-volatile Memory for Virtual Machines

Vimalraj Venkatesan, Wei Qingsong, Y.C. Tay
2014 2014 IEEE Intl Conf on High Performance Computing and Communications, 2014 IEEE 6th Intl Symp on Cyberspace Safety and Security, 2014 IEEE 11th Intl Conf on Embedded Software and Syst (HPCC,CSS,ICESS)  
However, the size of transcendent memory is unstable and frequently fluctuates with changing workloads. Contention among VMs over transcendent memory can cause increased cache misses.  ...  Such consolidation helps reduce the amount of idle resources. In particular, transcendent memory is a recent idea to gather idle memory into a pool that is shared by virtual machines (VMs).  ...  ACKNOWLEDGMENT We would like to thank the anonymous reviewers for their feedback and suggestions for improvement.  ...

ML-CLOCK: Efficient Page Cache Algorithm Based on Perceptron-Based Neural Network

Minseon Cho, Donghyun Kang
2021 Electronics  
For evaluation, we implemented a prototype of ML-CLOCK based on trace-driven simulation and compared it with the traditional four replacement algorithms and one flash-friendly algorithm.  ...  In this paper, we propose a new page replacement algorithm, called ML-CLOCK, that embeds single-layer perceptron neural network algorithms to enable an intelligent eviction policy.  ...  In order to solve this trouble, we designed an ML-CLOCK that utilizes the mechanism of SLP for determining which one has more meaningful effects on the eviction policy.  ...

PS-BC

Feng Chen, Xiaodong Zhang
2010 Proceedings of the 16th ACM/IEEE international symposium on Low power electronics and design - ISLPED '10  
Our experimental studies based on a trace-driven simulation show that the PS-BC framework embedded with the CLOCK replacement policy can achieve an energy saving rate of up to 32.5% with a minimal overhead  ...  However, replacement policies can also strongly affect energy consumptions of various connected storage devices, which has not been a consideration in the design and implementation of buffer cache management  ...  CLOCK-Pro [13] or LIRS [15] ) to be integrated into the management of the priority region, which has several merits.  ...

AMSQM: Adaptive multiple super-page queue management

Moshe Itshak, Yair Wiseman
2008 2008 IEEE International Conference on Information Reuse and Integration  
However, nowadays operating system's page replacement mechanism still uses the old CLOCK algorithm which gives the same priority to small and large pages.  ...  In this paper, we show a technique that enhances the page replacement mechanism to an algorithm based on more parameters and is suitable for a super-paging environment.  ...  CLOCK-Pro (Jiang et al., 2005) counts for each page the number of other distinct pages accesses since its last access.  ...
