摘要
通过对网格计算中资源协同调度机制的研究,根据该机制的资源协同分配需求,提出一个以Globus Toolkit为平台的基于网格计算的分布协同计算模型。在基于经济模型的作业调度机制的竞价机制中,给出一个较为完善的价格函数模型以及相应的作业预测完成时间模型,利用设计的价格函数模型实现资源提供的主观能动性,使得资源的调配更加合理、快速。同时,在分布式计算模型中还给出一个基于备份的作业调度容错机制。
Through the research of the grid computation in the resources coordination dispatch mechanism,according to this mechanism＇s resources coordination assignment demand,this paper proposes a take Globus Toolkit as the platform based on the grid computation distribution coordination computation model.In the scheduling mechanism＇s tendering mechanism based on economic model,this paper gives the price function of a more comprehensive model and the corresponding job completion time prediction model,the design cost function model provided by the initiative of resources,makes resource allocation more reasonable and fast.Meanwhile,it also gives a backup job scheduling based on fault-tolerant mechanisms in a distributed computing model.
