Popis
Shrnutí:Grid is proposed to solve large scale and complicated problems, and it is a form of parallel computing on Internet. Task scheduling in grid is one of the most important technologies in grid system, and it is a NP complete problem, which is used to schedule a task on an appropriate grid node. Task scheduling algorithms are used to improve the grid performance by minimizing the scheduling length. A priority-based task scheduling algorithm (P-TSA) in grid is proposed in this paper. In this kind of priority-based algorithm, tasks are scheduled according to the priority order firstly. And then assign processors Comparing P-TSA with existed grid scheduling algorithms on scheduling length and resource utilization rates. Simulations are done on examples of DAG, and simulation results shown that the performance of P-TSA is better than other scheduling algorithms such as Min-min and Max-min.
