Hi Andrew,
Thanks - my input in the running text below.
General points
- bios of participants (pull from websites)
- comment that others are expected to participate, but details not yet
agreed.
- workshop should be in the middle.
- note that we are also proposing a main track talk, and ideally that
would be on Saturday, with the dev room on Sunday.

Better title "Who ate my battery? Why energy efficiency matters"
This introductory talk will set the context for the entire devroom. It
will look at how energy efficiency is *the* major challenge for systems
developers. It will then provide an overview of a number of open source
projects that showing how energy efficiency of the entire system can be
significantly improved.

This talk will take the form of a tutorial with Q&A throughout,
exploring the various factors in hardware, software and system design
that affect energy consumption. Participants are invited to discuss
their particular projects, to help address specific areas where energy
may be an issue.

James Pallister is the designer of the open source PowerSense shield,
capable of accurately measuring the power consumption of a device up to
6 million times per second. He'll present the design of PowerSense and
show how it can be used.

I suggest workshop goes here (comments below)

MAGEEC, a collaboration between the open source software house,
Embecosm, and Bristol University's microcomputer gorup, aims to use
machine learning to improve the energy efficiency of compiled code. This
entirely open source project is funded by the UK government through its
Technology Strategy Board, and aims to provide working systems based on
LLVM and GCC by the end of 2014.
In this talk, Simon Cook, lead engineer on the project, will introduce
the system, so that participants can use it with their own code. He'll
be joined by colleagues specializing in the machine learning side, who
will show how this strategy can lead to better code.
This will be an interactive session, and the hope is that other
participants will be able to contribute more benchmark test cases to
improve the machine learning algorithms.

Need to bring out open source aspects. I suggest tie in to the
importance of ordinary users being able to see how much energy their
software is using.

Glen Anderson, Hayden Field (Bristol University)
As and undergraduate project, Glen Anderson and Hayden Field have
defined an open framework which eables the development of applications
that provide information about past and predicted energy usage directly
to the user. The two APIs replace platform specific instrumentation, one
providing energy information available to other software in a portable
way, the second providing access to energy information, without the need
for bespoke instrumentation on each platform.
In this talk Glen and Hayden will present their work

...Or bring along your own design on a breadboard and we'll hook up a
power sense shield to measure the energy usage.
As noted, this should be in the middle.
8. Energy efficiency, open source and the UK Technology Strategy Board
(speaker name to be confirmed).
In this short talk, we'll hear how the UK's innovation agency, the
Technology Strategy Board (TSB) promotes energy efficient computing, and
their willingness to embrace open source projects. The engagement of
government as both funder, and through Knowledge Transfer Networks
communications provider, is a key to fast development in this field.
9. A SystemC model of multicore OpenRISC with power instrumentation
This talk is subject to confirmation...
HTH,
Jeremy
