Round Robin Scheduling Not Power-Efficient

Posted by kdawson on from the toward-cooler-server-farms dept.

Via_Patrino writes "While having to distribute load between several servers, round robin, or any other technique that balances load equally, is the most common approach because of its simplicity. But a recent study shows that trying to accumulate load on some servers can improve energy efficiency because the other servers will be mostly unused during off-peak periods and then able to make better use of power saving methods. Specially, where load involves lots of concurrent power-consuming TCP connections, which was the case in the study, a new load-balancing algorithm resulted in an overall 30% power savings. Here's the paper (PDF)."

    I don't think that we should go down this road again - why don't we talk about religion or politics, instead?

      Can we just stick to politics? Why spoil a perfectly good Friday with a vi vs emacs debate?
