Abstract

While implementing many of the same operations, real-time and general-purpose operating systems strive to achieve fundamentally different goals: guaranteed performance vs. useful features, responsiveness, fairness, and graceful degradation. However, the high performance of modern computing hardware, the ubiquity of multimedia, and the growing complexity of real-time systems call for the integration of these two disparate processing models. This talk discusses ongoing research to merge hard real-time, soft real-time, and best-effort processing. It includes an overview of the issues and discusses our progress and plans in this area, including integrated CPU scheduling, slack management, storage Qos, and, time permitting, a case study demonstrating some of the benefits of this approach for control systems, a canonical hard real-time application.
