ViRUS: Virtual Function Replacement Under Stress

Authors: 

Lucas Wanner and Mani Srivastava, University of California, Los Angeles

Abstract: 

Abstract—In this paper we introduce ViRUS: Virtual function Replacement Under Stress. ViRUS allows the runtime system to switch between blocks of code that perform equivalent functionality at different Quality-of- Service levels when the system is under stress — be it in the form of scarce energy resources, temperature emergencies, or various sources of environmental and process variability — with the ultimate goal of energy efficiency. We demonstrate ViRUS with a framework for transparent function replacement in shared libraries and a polymorphic version of the standard C math library in Linux. Case studies show how ViRUS can tradeoff upwards of 4% degradation in application quality for a band of upwards of 50% savings in energy consumption.
