摘要
网格系统为管理和调度跨越不同区域的资源提供了一种虚拟框架。该文提出了一个基于HMA的网格资源调度系统以实现资源发现和调度;给出了一个新型的代价模型,它比传统的代价模型更多地考虑了资源发现代价和资源决策代价。随后,将新型代价模型集成到基 于HMA的网格资源调度系统中。对比实验显示,新型代价模型下的最优解优于传统代价模型下的最优解。
Grid systems can provide a virtual framework for management and scheduling of resources across different domains. This paper proposes an HMA Grid resource scheduling system to implement resource finding and scheduling. A new cost model is given, considering resource finding cost and resource deciding cost beyond traditional model. In succession, the new cost model is integrated into the HMA grid resource scheduling system. The experiment shows that optimal solution under traditional cost model is no longer optimal under the model.
