摘要
针对网格资源的可靠性问题,提出了一个包括注册真实性、信任评价和调度契约构成的分层控制模型。针对该模型,提出了资源注册信息的验证方法和契约的模式。仿真实验表明,该模型在资源注册信息验证的基础上,优先调度了信息真实、运行可靠的资源,通过可靠性资源的选择和控制促进了计算经济的可靠性。
A reliability control model of grid resource is proposed by samdwich which include facticity enrolling, credit evaluating and scheduling contract. Based on the control model, enroll information validating of grid resource and contract schema is discussed in detail. Finally, simulations performed to compare the performance of reliability control scheduling algorithm with that of the none reliability control. The experiments show that the reliability control scheduling algorithm is efficient on resource selecting and valuable within grid computing economy environments.
