Energy effficient cache node placement using genetic algorithm & cooperative caching algorithm

2015 2nd International Conference on Electronics and Communication Systems (ICECS), 2015
Optimization of communication among sensors to serve data in short latency and minimal energy is necessitated for some of the wireless sensor network applications. For a self-organizing wireless sensor network Genetic Algorithm based multi-objective methodology is developed and is used as a technique in the selection of sensor nodes which play special ...

Cache Line Aware Algorithm Design for Cache-Coherent Architectures

IEEE Transactions on Parallel and Distributed Systems, 2016
The increase in the number of cores per processor and the complexity of memory hierarchies make cache coherence key for programmability of current shared memory systems. However, ignoring its detailed architectural characteristics can harm performance significantly.

Algorithms for Cache Placement

2011
The results of the preceding chapter show that the SCPP is very difficult to solve, even if only approximate solutions are required. We describe some approximation algorithms that can be used to give solutions to the problem, and decrease the gap between known solutions and nonapproximation results.

A novel cooperative caching algorithm for massive P2P caches

Peer-to-Peer Networking and Applications, 2013
For an ISP (Internet Service Provider) that has deployed P2P caches in more than one ASs (autonomous systems), cooperative caching which makes their caches cooperate with each other can save more cost of carrying P2P traffic than independent caching.

Competitive Algorithms for Restricted Caching and Matroid Caching

2014
We study the online restricted caching problem, where each memory item can be placed in only a restricted subset of cache locations. We solve this problem through a more general online caching problem in which the cache is subject to matroid constraints. Our main result is an O( min {d,logr} ·logc)-competitive algorithm for the matroid caching problem,

Cache Replacement Algorithms for YouTube

2014 IEEE 28th International Conference on Advanced Information Networking and Applications, 2014
In recent years, many social network systems like, YouTube, Facebook, Twitter, etc. have been a part of our everyday life. Among these systems, YouTube which plays video programs of different interesting themes for users has been one of the most attractive ones.

SF-LRU cache replacement algorithm

Records of the 2004 International Workshop on Memory Technology, Design and Testing, 2004., 2004
In this paper we propose a replacement algorithm, SF-LRU (second chance-frequency - least recently used) that combines the LRU (least recently used) and the LFU (least frequently used) using the second chance concept. A comprehensive comparison is made between our algorithm and both LRU and LFU algorithms.

Cost-sensitive cache replacement algorithms

The Ninth International Symposium on High-Performance Computer Architecture, 2003. HPCA-9 2003. Proceedings., 2003
Cache replacement algorithms originally developed in the context of simple uniprocessor systems aim to reduce the miss count. However, in modern systems, cache misses have different costs. The cost may be latency, penalty, power consumption, bandwidth consumption, or any other ad-hoc numerical property attached to a miss.

Caching algorithms for similarity search

2009
Similarity search in metric spaces is a general paradigm that can be used in several application fields. One of them is content-based image retrieval systems. In order to become an effective complement to traditional Web-scale text-based image retrieval solutions, content-based image retrieval must be efficient and scalable.

Cache-oblivious Algorithms

2012
In this work, we study the cache-oblivious computation model, which is inspired by the behaviour of the memory hierarchy of current computers. We study several graph algorithms and techniques of their design in this model. We consider graph searching, identifying connected components and computing maximal matching.
