Objective

Learn the commonly used software techniques for controlling power consumption in computers.

Description

Requirements

computer architecture basics.
basic knowledge about operating system internals (what’s the scheduler, what’s an interrupt)

    I think this would be a good talk. I would like to learn more about how conflicts of interests between “power management” and “performance” can lead to failures on both fronts: more power consumption and poorer performance.

    It would be enlightening to learn how application developers and operations engineers could work /with/ their operating systems, rather than /against/ them, to balance power management and performance concerns.
