Computer scientists have developed a tweak for computer operating systems that could make large data centres 25 per cent more efficient by sharing their processing power. Researchers at The Australian National University (ANU) and Microsoft collaborated to develop the new system mechanisms, which give big improvements in energy efficiency for servers that run searches and interact with users.
