Scheduling Policies Supporting Co-allocation and Advance Reservation for Large-Scale Distributed Environments

Resource co-allocation is one of the crucial technologies affecting the utility and quality of services of large-scale distributed environments by simultaneously allocating multiple resources to one application. This paper concentrated on the problem to guarantee the QoS of co-allocation jobs via advance reservation and investigated the performances of two typical scheduling algorithms with and without advance reservation. Simulations have shown that advance reservation is effective to improve the QoS of co-allocation.
