Von Liebig and SleepServer in San Diego Business Journal

Monday was the third day of a three day weekend, and how many PCs in corporations, universities and other organizations were running on Monday even though the usual users were enjoying the holiday?

Monday was also the day the San Diego Business Journal ran a story describing the UC San Diego technology aimed at fixing these sorts of problems. SleepServer lets users put their enterprise PCs to sleep without the fear that they won't be able to access them remotely. The lightweight image of each sleeping PC can also run stripped down programs that enable the PC to work while it sleeps.

Check out the SleepServer story here on the SDBJ Web site.

Technology Review ran a SleepServer story last week.

Update Thursday July 8: The La Jolla Light ran a SleepServer story "Research Report: PCs can work while they sleep."

Gizmag Glances at SleepServer

Gizmag has a SleepServer story up on their super-high-traffic tech blog today.

Check it out...and the easy-to-read summary from the Jacobs School of Engineering is here, and a longer, more technical summary is here.

PCs Sleep (and Work) Through the Night with SleepServer

Leaving your computer on all night/weekend/break just in case you need to connect remotely…that’s SO last decade. UC San Diego computer scientists created software that lets you put your computer to sleep without worrying that you’ll have to schlep your way to campus on Saturday night just because you suddenly need to access your computer connected to an enterprise network. SleepServer wakes up your sleeping PC remotely when you need it…but it won’t wake up the PC if the PC’s alter ego – a lightweight virtual image – can handle the job.

That’s the simplest example of how SleepServer helps UC San Diego cut its carbon footprint. But SleepServer does much more. That sleeping computer of yours also remains active on voice over IP/IM/peer-to-peer networks as well thanks to SleepServer.

How is this possible? When you put your computer to sleep, the software activates a lightweight virtual image of your PC which runs on a commodity server, along with hundreds of images of other PCs on your network. That virtual image can do a number of basic things that would otherwise require the actual PC to be awake.

SleepServer reduces energy consumption on enterprise PCs previously running 24/7 by an average of 60 percent, according to a new study presented today at the 2010 USENIX Annual Technical Conference.

Yuvraj Agarwal from UC San Diego is presenting this work TOMORROW June 25 in Boston at the 2010 USENIX Annual Technical Conference.
