网格资源选择性配置研究

Research of Grid Selective Resources

网格是一种复杂的分布式计算系统,研究其在有限容量条件下的多元受限任务等待问题具有重要的意义。网格资源选择性配置方案正是针对解决网格资源不合理利用所提出的。分析了网格环境下的数据共享和任务调度,研究了有限容量条件下的多元受限任务等待问题,提出了网格资源选择配置方案,并考虑在多任务和资源受限的情况下,通过引入脉冲函数来建立数学模型并对其进行仿真计算,验证了该模型的正确性与可行性。

As such a complex distributed grid computing system, this system wants to study the problems of the multiconstrained task expectance under the condition of limited capacity. So it behaves greatly important. Based on the unreasondable uesing, we adressed the selective configuration of grid resources. This article analyzed the grid environment, data sharing and task scheduling, studing under the conditions of the limited capacity of the multi-constrained task expectance , to adress the selective configuration of grid resources. Considering the impact of multi-tasking and resourceconstrained circumstances, a pulse function mathematical model was introduced and simulated to verify the feasibility of the model.
