Executive Summary

In grid systems, co-allocation is a key infrastructure to schedule heterogeneous and distributed resources for high-level applications. Although it has been widely studied, QoS-based resource co-allocation still remains an unsolved issue. In this paper, the authors propose a novel QoS-based co-allocation model for the grid applications with constraints to budget and deadline. A new concept, called Virtual Resource Agent, is introduced into the co-allocation policy. Theoretical analysis indicates that Virtual Resource Agent can provide quantitative QoS guarantee for applications in terms of budget and deadline.
