User Level Scheduling of Communicating Real-Time Tasks
Unique challenges are present when one tries to build distributed real-time applications using standard o -the-shelf systems which are in common use but are not necessarily designed speci cally for real-time systems. In particular, to realize end-to-end predictability when, say, a process on one node sends data to a process on another node, several issues must be addressed: 1 mapping application real-time requirements into requirements imposed on the system schedulable entities tasks, 2 ensuring predictable execution of the tasks in the face of possible priority inversions, limited OS level real-time scheduling support, and limited number of priorities, and 3 integrating real-time and non-real-time tasks in the same platform. In this paper, we propose solutions to these challenges. In particular, we present user-level scheduling schemes for communicating tasks. These solutions are practical and are based on simple primitives that can be found in most of today's commonly used oper...
