Abstract [en]

Functionality for various services of scheduling algorithms is typically provided as extensions to a basic paradigm, intertwined in the kernel architecture. Thus, scheduling services come in packages around single paradigms, fixed to a certain methodology and kernel architecture. Temporal constraints of applications are addressed by a combination of scheduler and system architecture. Consequently, changing system architecture results in a complete rescheduling of all tasks, calling for a new cycle of analysis and testing from scratch, although a schedule meeting all temporal constraints already existed.

We propose a component based architecture for schedule reuse. Instead of tying temporal constraints, scheduler, and system architecture together, we provide methods which allow for the reuse of existing schedules on various system architectures. In particular, we show how a schedule developed for table driven, dynamic or static priority paradigm can be reused in the other schemes.

We address an architecture to disentangle actual scheduling from dispatching and other kernel routines with a small interface, suited for a variety of scheduling schemes as components.
