Contextual Bandit Modeling For Dynamic Runtime Control In Computer Systems, Jason Hiebel

Dissertations, Master's Theses and Master's Reports

Modern operating systems and microarchitectures provide a myriad of mechanisms for monitoring and affecting system operation and resource utilization at runtime. Dynamic runtime control of these mechanisms can tailor system operation to the characteristics and behavior of the current workload, resulting in improved performance. However, developing effective models for system control can be challenging. Existing methods often require extensive manual effort, computation time, and domain knowledge to identify relevant low-level performance metrics, relate low-level performance metrics and high-level control decisions to workload performance, and to evaluate the resulting control models.

This dissertation develops a general framework, based on the contextual …
