Abstract
Power and temperature have joined performance as first-order design
constraints. Balancing power efficiency, thermal constraints, and performance
requires some means to convey data about real-time power consumption and
temperature to intelligent resource managers.
Resource managers can use this information to meet performance goals, maintain
power budgets, and obey thermal constraints. Unfortunately, obtaining the
required machine introspection is challenging. Most current chips provide no
support for per-core power monitoring, and when support exists, it is not
exposed to software.
We present a methodology for deriving per-core power models using sampled
performance counter values and temperature sensor readings. We develop
accurate, application-independent models for several CMPs, and show how they
can be used to guide scheduling decisions in power-aware resource managers
enforcing a specified power envelope.
