计算网格中经济模型的应用策略

基于经济模型的计算网格资源分配和任务调度, 将货物市场模型与拍卖模型进行比较. 通过对两种经济模型进行模拟, 分别在网格资源市场需求不足和需求过剩的条件下, 以资源价格的稳定性、 市场均衡、 资源利用率和作业执行效率为评价标准, 对两种经济模型的性能进行了评估. 结果表明, 货物市场模型比拍卖模型更适合计算网格环境, 并且能够产生更稳定的资源价格, 更容易达到市场均衡, 资源利用率和作业 的执行效率也更高.

The Economic Model Application Strategy in Computational Grids

The commodity market model was compared with the auction model from the aspects of resource allocation and task scheduling based on economic models in computational grids.To evaluate these two models,we simulated them respectively in under-demand and excess-demand circumstances.We have examined the overall price stability,market equilibrium,producer efficiency,and consumer efficiency by simulation and drawn a conclusion that the commodity market model is more suitable to computational grids,and makes the wh...
