Previous: SMP Scheduling
- Real-time processes characterised by a deadline.
- OS must be able to guarantee completion by deadline.
- Requires:
- predictable execution,
- predictable and limited system overheads,
- preemtability of long system calls,
- kernel locking, reentrancy...
- similar requirements as for SMP
- analysis of schedulability prior to process admission,
- careful scheduling.
