Saving power has become a mainstream concern in the enterprise and at home, as IT users aim to cut costs and do their part to help save the planet.
There are a lot of different ways that technology users can reduce their power, and chip maker Intel is putting a number of them under one umbrella called Less Watts. The only caveat, though, is that it's targeted specifically at Linux users.
"What's interesting about this project is that it's an umbrella project covering a broader range of things already in existence," Dirk Hohndel, Chief Linux and Open Source Technologist, told InternetNews.com. "It's an open source project and we want to create a community that shares tips, helps each other and creates a focal point around saving power."
There are also already efforts in the Linux kernel, including the "tickless idle," which is a power saving-feature that aims to reduce power consumption while the OS is idle.
At the core of power conservation for Intel is getting the operating system to do less needless work. "The biggest power waster is that system wakes up thousands of times per second to do things it doesn't need to do," Hohndel said.
Using some of the tools and tips that Less Watts offers, an enterprise could save 10 watts of power on a normal dual processor server, Hohndel continued. Add to that the fact that for every watt that isn't created you save 1.3 watts in energy needed to cool the server.
"The impact is dramatic," Hohndel said.
He admitted that the projects listed on Less Watts are all tested and developed for Intel silicon, though he had no doubt that they could potentially impact other vendors, including rival AMD.
As a community open source project, Hohndel said Intel is not restricting the effort to be just Intel, though Intel is the focus since they are the ones that started the effort. Linux vendors Red Hat and Novell have also endorsed the project.
Less Watts is geared toward Linux users as opposed to users of any other operating system. Hohndel explained that applying some of the techniques described on the site would be difficult, though not impossible, to port to other operating systems.
As an example he cited the tickless idle changes in the Linux kernel, which he described as being at the very core of the operating system and could not be easily transported.
Though Intel has focused Less Watts on Linux, that doesn't necessarily imply that Intel believes that Linux is a more power-efficient operating system than others. Or does it?
"It's extremely hard to benchmark other OSs," Hohndel said. "It's difficult to do, so we have not spent the time trying to create fair benchmarks."
