We present a multiprocessor scheduling framework for integrating hard and soft real-time tasks and best-effort jobs. This framework allows for full system utilization, and ensures that hard real-time deadlines are met and that deadline tardiness is bounded for soft real-time tasks. Dynamic slack reclamation is employed to reduce tardiness and to improve the response time of best-effort jobs. The approach is validated using an implementation within the Linux kernel.
