Capabilities for per Process Tuning of Distributed Operating Systems
Résumé
This paper introduces capabilities as a tool to tailor cluster mechanisms usage on a per process basis in a single system image operating system. Using capabilities, processes should only pay the cost in terms of OS resources for the operating system of the mechanisms they want to use. We relate capabilities to policies that are used to try to ensure optimal resource usage across all cluster nodes. Finally, we discuss implementation of these ideas in Kerrighed and describe its usage on a real industrial application.
