The working characteristics provide the guarantees, and the boundaries of applicability delimit the regions within which the guarantees hold. Meta adaptation provides the transition from one guaranteed region to another when boundaries of applicability are crossed. This Microfeedback research supports scalable, composable, and predictable adaptation in the management of system resources. Composability is by design and construction of the Microfeedback Toolkit and the adaptive resource schedulers that use microfeedback. Predictability is due to the conditional guarantees provided by microfeedbacks within their boundaries of applicability.
Scalability is the result of explicit meta-adapation when boundaries of applicability are crossed.
