To the time-constrained workflow scheduling in grids, this paper proposes a new scheduling algorithm in terms of the finite-state continuous-time Markov process through selecting a resource combination scheme which has the lowest expenditure under the certain credit level of the resource reliability on the critical path in the DAG-based workflow. The simulation shows the validity of theory analysis.
As Grid networks grows, the complexity of resource management in Grid networks dramatically increases. To manage the Grid resources efficiently, policy based resource management system is suitable. However, the policy which made at a moment could not be appropriate to other time because the condition of the grid resources with time space changes. Thus, in this paper, we propose asynchronous policy-based...
