Abstract
Abstract A computer system is programmed with a CPU intensive application that self-regulates its consumption of CPU cycles. More specifically, the CPU intensive application includes mainline logic that are designed to be able to be executed at different functional levels, consuming different rates of CPU cycles, and self-regulating logic for monitoring CPU load, and decrementally adapting the CPU intensive application to decreasingly lower functional level, and therefore lower rate of CPU cycle consumptions, in accordance to a set of adaptive policies. The set of adaptive rules specify a number of domain specific responses to various CPU load conditions.
