Continuous Reactability of Persistent Computing Systems

Persistent computing systems are an infrastructure of computing anticipatory systems. The reactability of a persistent computing system, which is how many reactions of the system are active at a certain time, is the most important property to characterize the system. On the other hand, to be anticipatory, the reactability of a computing anticipatory system must be continuous. This paper proposes the first method to measure the continuous reactability of a persistent computing system in a unified way. The continuous reactability of a persistent computing system is a new concept of computing systems, so that it will be raise new research problems of computing anticipatory systems as well as persistent computing systems.
