Abstract
This paper presents PowerDial++, a system for dynamically adapting
both application and system configuration in response to
unpredictable changes in application workload, available power, or
user goals. PowerDial++ coordinates the management of application
parameters governing performance versus accuracy tradeoffs with
system parameters governing performance versus power tradeoffs. Our
results show that PowerDial++'s coordinated approach provides a
greater range of operating points than application or system
configuration alone. For example, PowerDial++ can meet energy
efficiency goals with greater accuracy or meet accuracy goals with
reduced power consumption compared to prior approaches.
Additionally, PowerDial++'s ability to manage goals in multiple
dimensions provides greater efficiency in response to unpredictable
changes in application input or user goals.
