A Consensus-Based Framework for Responsive Computer System Design
The concept of responsive computer systems is presented. The emerging discipline of responsive systems demands fault-tolerant and real-time performance in both parallel and distributed computing environments. The responsiveness measure is discussed and a new design framework for responsive systems is introduced. The new framework is based on the fundamental concept of consensus and on application specific responsiveness. It is shown that consensus is crucial in responsive synchronization, communication, diagnosis, and reconfiguration.
It is also illustrated how these tasks form a part of the consensus-based operating system, and, when combined with application specific methods, handle fault-tolerance and real-time issues germane to a given application. This approach seems to be the most appropriate for the design of fault-tolerant, real-time, parallel/distributed systems.
