3、 Managing this huge amount of data in a centralized way is ineffective due to extensive access latency and load on the central server. Data Grids aggregate a collection of distributed resources placed in different parts of the world to enable users to share data and resources. Data replication is an
4、 important technique to manage large data in a distributed manner. There are three key issues in all the data replication algorithms which are replica placement, replica management and replica selection. Meanwhile, even though the memory and storage size of new computers are ever increasing, they ar

Effective scheduling in the Grid can reduce the amount of data transferred among nodes by submitting a job to a node where most of the requested data files are available. Effectiv
9、e scheduling of jobs is necessary in such a system to use available resources such as computational, storage and network efficiently. Storing replicas close to the users or grid computation nodes improves response time, fault tolerance and decreases bandwidth consumption. The files of Grid environme
10、nts that can be changed by Grid users might bring an important problem of maintaining data consistency among the various replicas distributed in different machines. So the sum of them along with the proper weight (w1,w2) for each factor yields the combined cost (CCi,j) of executing job i in site j.

We conclude that replication policies should rely on a-priori information about file accesses, such as file type or workflow relation.篇二：科研文献阅读笔记模板(word版)(个人版本2.0) 文献阅读笔记 主要内容：_ 阅读时间：_ -第1页- (本页特意留作空白) -第2页- 目 录 文献1： . 3 文献 2： . 4 文献 3： . 5 文献 4： . 6 文献 5： . 7 文献 6： . 8 文献 7： . 9 文献 8： . 10 文献 9：
