As multimedia applications with real-time constraints rapidly invade today's desktops, it becomes increasingly important for the operating system to provide robust resource allocation mechanisms for both multimedia and traditional best-effort workloads. We present a flexible CPU scheduling policy that adjusts the CPU proportion allocated to each application class using recent history as a feedback mechanism. The algorithm quickly adapts to varying workload conditions and compares favorably with static proportional scheduling schemes for mixed workloads
