Soft Real-Time on Multiprocessors: Are Analysis-Based Schedulers Really Worth It?
2011
2011 IEEE 32nd Real-Time Systems Symposium
The evolution of multicore platforms has led to much recent work on multiprocessor scheduling techniques for soft realtime workloads. However, end users routinely run such workloads atop general-purpose operating systems with seemingly good results, albeit typically on over-provisioned systems. This raises the question: when, if ever, is the use of an analysisbased scheduler actually warranted? In this paper, this question is addressed via a video-decoding case study in which a scheme based on
