A Task Schedule Algorithm Based On GRIDSIM Simulation Platform

With the quickly development of Internet and electric commerce, people realize a epoch-making novelty--grid appearing at interdisciplinary domain which correlate with high performance computation.Its appearance will bring the 3rd tidal wave–grid computing after Internet and Web. Grid linked internet, high performance computers, databases, remote equipments and so on. Grid will furnish more and more resources, function and interactivity for all of us.In fact, Internet accomplished joins of computer hard, Web accomplished join of web page, grid want to accomplish join of all resources at Internet. Grid will integrate all of Internet to a huge virtual super computer shared with computation resources, store resources, communication resources, software resources, information resources and knowledge resources. In fact, the 3rd tidal wave–grid computing is sublimating web to great global grid.Now, Grid has become a hot spot of Internet domain, many foreign experts focus on it and bring forth many new fruits. Especially, task schedule problem of grid computation has become hot spot problem in grid research field. But many research are based on mathematical model, ignored real grid model platform.So, the author of the paper bring forth a task schedule algorithm based on a 3-level grid model. Finally, I make a series of analogy experimentations based on gridsim to prove reliability of our algorithm.This paper will be divided into 5 parts. First of all, we introduce some basic...
