The Research On Dispatching Method Of Long Transaction For Pallel Transmission

The database application is more and more comprehensive along with the computer's universal application in various trades and occupations .In the parallel transmission ,the problem of the scheduling of the long business is more and more obvious day by day, in which long business processing and the dispatching are essential questions. The research of dispatching method is imperative . Enhancing the system concurrency and keeping the balance of the network load have the extremely vital significance.This article researched emphatically the algorithm of the duty assignment and the dispatch which is appropriate for this system,which was based on analyzing the task dispatch the parallel transmission platform system and the common dispatch algorithm about central task . The task scheduling algorithm which the paper research uses the balanced dynamic task scheduling tactics and distributes the assignment to different parasite computer. The decision must be made before executing and carries it out and adjust dynamically the duty when it is carring out. We researched a simulative on the algorithm and analyzed the result of our algorithm and got the conclusion so that we solved the difficult problem of the long business's parallel transmission and dispatching in the large-scale network system.
