【摘要】 针对渲染网格的特点提出了渲染网格的二个调度模型。模型一提出了在局部资源的计算结点内,采用基于用户优先级的CPU频度轮转调度方案,达到提高系统吞吐率的目的。模型二提出了适合市场机制的渲染网格调度模型,并给出了竞标的报价算法。该算法在公共网格开放软件GlobusToolkit4.0上实现,符合国际标准WSRF规范。实验结果表明本调度策略在处理渲染网格任务时性能得到了很好的体现。更多还原

【Abstract】 In the paper,two scheduling models of rendering grid are presented in light of the characteristics of it.The first one aims at improving system throughput and uses a scheduling mechanism of user priority based CPU frequency cycling within computational node of local resource.The second one is a scheduling model adapted to market competition.An algorithm of computing price for global bid mechanism is given as well.更多还原
