Dynamic Data

A grid scheduling method based on hierarchical scheduling strategy and Dynamic Data replication Rai Jinhui Liangsong, the Task scheduling algorithm (YPP) and the Dynamic Data replication algorithm (E1/ZF) are proposed to solve the problem of how to efficiently perform task scheduling and data replication in grid, so as to reduce task execution time.　and construct a scheme to combine the two algorithms effectively. The scheme uses YPP algorithm to comprehensively consider the number of task waiting queue, the location of task demand data and the calculation capacity of the site, and adopt the hierarchical scheduling method of network structure, with the appropriate weight coefficient calculation ...

In the project, a reasonable use of caching is of great help to performance. Thinkphp provides a convenient way to cache, including data caching, static caching, and query caching, and support including file mode, APC, Db, Memcache, Shmop, Sqlite, Redis, Dynamic Data cache types, including eaccelerator and XCache, and 17813.html "> Customizable static caching rules, and provide a quick way to access operations. Data caching in thinkphp ...

A dynamic cloud storage data integrity verification method based on Homomorphic label Yu Shing in the cloud storage service, a Dynamic Data integrity verification method based on Homomorphic label is proposed to enable users to verify the integrity of the data stored on the cloud storage server at any time. By introducing the homomorphism label and the user randomly selecting the data block to be detected, the data can be validated indefinitely. and support data dynamic update; the introduction of trusted third party solves the dispute of data integrality between cloud user and cloud storage service provider, and realizes the public verification of data integrality, then gives the method ...

Information-Type News-Jiangholiang system The left spring takes into account that the picture has a strong interpretation of events, the characteristics of the dissemination of convenience, research from a large number of data-intensive news Web pages automatically extracted data, and organize a complete set diagram structure to show the user. Dynamic page extraction and parsing are realized based on page template, and processing is converted to the corresponding data structure. Based on cosine correlation, the data from different websites are weighed and sorted according to the corresponding standards. Considering the huge news data and the number of users, this system is based on Hadoop distributed platform to meet the ...
