It is assumed in this paper that periodic real-time applications are being run on a cluster of heterogeneous workstations, and new non-periodic real-time applications arrive at the system dynamically. In the dynamic scheduling scheme presented in this paper, the new applications are scheduled in such a way that they utilize spare capabilities left by existing periodic applications in the cluster. An admission control is introduced so that new applications are rejected by the system if their deadlines cannot be met. The effectiveness of the proposed scheduling scheme has been evaluated using simulation; experimental results show that the system utilization is significantly improved.
