A Quick Construction Method And Application Of Grid Computing Platform

The resource share of many local grid becomes research focus along withthe progress of grid technology, but the current system has a common defectknown as hard to use, hard to deploy and complex construction. Thedestination of CPSCG(Constructive Platform of Specific Computing Grid) isincreasing deploy efficiency and connecting users and resources with a higheffective platform.The achievement of this paper is:1. We bring forward a basic rule which is "Domain do and only do itsown works". Further more, we conclude three principles: "Job stub followsuser, data follows job, job follows service" and a clear definition of gridworkflow;2. P2P architecture is imported into the grid network topology andcombined with the hierarchy architecture, so the coupling between domains isextremely decreased and we got more extensibility from it.3. In job scheduling, we use a two-layer schedule pattern, i.e., theinter-domain schedule and the intra-domain schedule. Meanwhile, theimplementation is hided from end users, so we separate the internal detail ofsystem from users and keep users' choice free;4. For the command line style software, we design a XML descriptionscheme to pack them as services. Beyond this, we implement theauto-generate and auto-deploy functions of services based on the scheme, sothe software deployment becomes a easy work;5. We introduce the concept of Web Service API and propose a set ofAPI as the reference standard, the concept is great contribution to use patternof computing grid because it satisfies users in different levels and enrich theuse patterns of grid.
