2014 International Journal of Modern Education and Computer Science  
This paper also analyses the performance of various strategies with respect to the parameters mentioned above in data grid.  ...  In data grids, data replication on variant nodes can change some problems such as response time and availability.  ...  When cascading is combined with caching strategy, a locally cached file which is frequently requested by clients is cascaded down in the hierarchy by the server.  ...

Diversified caching for replicated web search engines

Chuanfei Xu, Bo Tang, Man Lung Yiu
2015 2015 IEEE 31st International Conference on Data Engineering  
Then we present a framework with a suite of techniques and heuristics for diversified caching.  ...  In this paper, we investigate the effect of caching on the throughput in such a setting. A simple scheme, called uniform caching, would replicate the cache content to all servers.  ...  Suppose that the replicated system contains two servers (S 1 , S 2 ); each server stores all P L j in disk and keeps a cache for P L j (in RAM) with a fixed capacity (e.g., 3 document IDs).  ...

Characterizing Load Imbalance in Real-World Networked Caches

Qi Huang, Helga Gudmundsdottir, Ymir Vigfusson, Daniel A. Freedman, Ken Birman, Robbert van Renesse
2014 Proceedings of the 13th ACM Workshop on Hot Topics in Networks - HotNets-XIII  
Within a given cache, items are typically partitioned across cache servers via consistent hashing, with the goal of balancing the number of items maintained by each cache server.  ...  We also employ trace-drive analytics to study the benefits and limitations of current loadbalancing methods, suggesting areas for future research.  ...  Acknowledgments We thank our HotNets reviewers for their constructive feedback.  ...

P. Yang, M. Chuah
2009 Computer Networks

Avoiding unconditional jumps by code replication

Frank Mueller, David B. Whalley
1992 Proceedings of the ACM SIGPLAN 1992 conference on Programming language design and implementation - PLDI '92  
The replication method is based on the idea of finding a replacement for each unconditional jump which minimizes the growth in code size, This is achieved by choosing the shortest sequence of instructions  ...  Measurements taken from a variety of programs showed that not only the number of executed instructions decreased, but also that the total cache work was reduced (except for small caches) despite increases  ...  For each different cache size a direct-mapped cache with 16 bytes per line was simulated. Both the miss ratio and the fetch cost were measured in the experiment.  ...

Combining replica placement and caching techniques in content distribution networks

Spiridon Bakiras, Thanasis Loukopoulos
2005 Computer Communications  
Caching and replication have emerged as the two primary techniques for reducing the delay experienced by end-users when downloading web pages.  ...  We develop an analytical model to quantify the benefit of each technique, under various system parameters, and propose a greedy algorithm to solve the combined caching and replica placement problem.  ...  Consequently, the CDF curve of the hybrid policy is a combination of the previous two: it initially follows the curve of the caching scheme for small delays, and later coincides with the curve of the replication  ...
