What and Who
Title:Mobile multi-cores: power and performance
Speaker:Aaron Carroll
coming from:NICTA, Sydney
Speakers Bio:Aaron Carroll is a final-year PhD student in the Software Systems
Research Group at NICTA and UNSW in Sydney, Australia, under the supervision of Prof.
Gernot Heiser. His research interests include mobile and embedded systems, power
management and measurement, operating systems, and multi-core performance, all
with a strong emphasis on practicality. He is currently interning in the
Efficient Computing group at Rice University, where he is exploring ways to improve
performance on multi-core processors beyond thread-level parallelism.

Abstract

The modern smartphone is a power hungry device, and due largely to the
proliferation of multi-core CPUs, the applications processor is one of
the main energy drivers. Indeed, a current-generation mobile multi-core can drain
your battery in well under one hour. In this talk I will discuss how to
manage mobile multi-cores more effectively. I will start with some ground-truth about
the energy consumption inside a smartphone, based on circuit-level measurements of
real devices. Noting that the applications processor continues to be
relevant, I will discuss some techniques for regulating multi-core CPU power, showing the
importance of static power and its surprising variance among devices.
Finally, I will conclude the talk discussing current and future work on exploring
alternate ways to utilize the parallelism available in mobile multi-cores.
