摘要：In this paper, we design global optimization model and fault tolerance service for grid computing system. It is provided as a promising model for grid resource scheduling algorithm. It aims at solving the problem of optimally allocating services on the grid to optimize the grid service reliability, deadline and cost. In this paper, the problem of optimizing the reliability of grid systems has been modeled as a multi-objective optimization problem where apart from the grid system reliability; the system cost and redundancy are also considered as objectives. For the reliability analysis of the grid system, we consider failure rate of computational resources and network resources. Based on the service reliability of the grid system, Our IGA-RORS algorithm selects the set of optimal resources among the candidate resources based on reliability, application execution time and cost that achieves optimal performance using an immune genetic algorithm. In our algorithm, we design and implement a fault tolerance service; it guarantees the completion of the applications in the optimally selected resources. We have demonstrated the test results in java based GridSim tool.
