Data centers are notorious energy consumers. In fact, studies have shown that for every $1 spent on hardware in the datacenter, $0.50 is spent on powering this hardware over its lifetime. Data centers host real or virtual (i.e., cloud) clusters that often execute large compute jobs using...

Don’t leave the lights on! One reason we take energy consumption seriously is because we are directly billed for it. If one leaves the heat on high over night the effect is noticeable on the next bill. Yet as granular as cloud computing billing can be in terms of resources and quality of service,...
