Abstract
A system and method for ensuring a minimum required availability of a Hosted Function (HF) may retain an entirety of a cache content between separate instances of one or more HF which may share a cache resource. Based on controlling a relationship between an unavailability of cache memory desired by the HF to a probability of the available cache being unusable by the HF, each activation period may be variable within a tolerance to achieve a certification strategy. The approach may statistically characterize a best case, expected case, and worst case of cache availability. The system and method may determine a quality of the cache state at the activation of a particular HF and, based on the statistical analysis of that quality over time, determine a desired derated activation period for each HF to achieve a minimum level of computational availability for successful activation of the HF.
