Fault Tolerant Real-Time Systems

Abstract

The ART (Advanced Real-Time Technology) Project is engaged in wide ranging research on hard real-time systems. The project has as its overall goal the development and demonstration of predictable and fault tolerant hard real- time computer systems. To achieve this goal, research is being conducted in three interrelated areas: The development of a theory of hard real-time resource management including scheduling and synchronization. In addition, this theory is being applied in a wide range of contexts including databases, communication networks, operating systems and artificial intelligence. The design and construction of an operating system (ARTS) that supports predictable and fault tolerant real-time computer systems and demonstration and testing in the ARTS testbed to provide proof of concept and to gain understanding into aspects of the theory needing further refinement. A real-time version of the Mach operating system, RT-Mach, is also being developed as a part of the project. Development of hardware architectures and approaches to fault tolerance that can support predictable hard real-time computer systems.
