Task Scheduling in Distributed System Based on Dynamic Multi Processing Nodes

LIANG Gen1,QIN Yong1,2,GUO Xiao-xue3,LIANG Huo-min4(1.Education Information and Technology Center,Maoming University,Maoming 525000;2.School of Computer Science & Engineering,South China University of Technology,Guangzhou 510641;3.College of Science,Maoming University,Maoming 525000;4.College of Computer Science,South China Normal University,Guangzhou 510631)  
Aiming at the problem of poor control ability of distributed system with fixed nodes,this paper gives a task scheduling model of distributed system.The problem of task scheduling in single node is discussed.In order to depict the capability of load-tolerance clearly,the processing intensity concept is drawn.The method of task scheduling among dynamic multi processing nodes is deduced to optimize the characteristic of responsibility time in task scheduling.Simulation experiments show that this algorithm has a better control ability,and it can reduce load of processor,improve the performance of the task-processed delay and use the resource of system more legitimately.
