Abstract: The paper considers QoS driven resource scheduling from application perspective, resource perspective and system perspective. The objectives of the individual applications, the individual resources, and the system are often in conflict. Application QoS parameters are expressed as a function of the application|s goals. Resource-level QoS parameters depend on the control parameters. In order to resolve the conflicts of the objectives of application and resource providers, the system needs to be aware of application QoS parameters and resource-level QoS parameters to find an optimal relation between user satisfaction and resource utilization. Experiments are conducted to test the performance of proposed algorithms.

Keywords: grid computing; QoS; quality of service; application perspective; resource perspective; system perspective; resource scheduling; user satisfaction.
