Abstract [en]

Streaming applications are often used for embedded and high-performance multi and manycore processors. Achieving high throughput without wasting energy can be achieved by static scheduling of parallelizable tasks with frequency scaling. We present asymmetric crown scheduling, which improves on the static crown scheduling approach by allowing flexible split ratios when subdividing processor groups. We formulate the scheduler as an integer linear program and evaluate it with synthetic task sets. The results demonstrate that a small number of split ratios improves energy efficiency of crown schedules by up to 12% with slightly higher scheduling time.
