Abstract:
This paper describes AGST, a simulator tool for autonomic grids based on discrete events. The simulator provides, among others, tools for modeling grid resources and their network interconnections, grid applications and their submissions, the occurrence of resource faults, resources local workload, and the use of workload and fault traces following the SWF and FTA standards. AGST major contribution is the definition of a simulation model of the autonomic management cycle MAPE-K, which allows the simulation and evaluation of autonomic grid middleware behavior, providing support for the monitoring, analysis, planning, and dynamic execution of reconfiguration actions to be applied to the simulated grid components.
