The CPU Frequency Scaling Monitor provides a convenient way to monitor the CPU Frequency Scaling for each CPU.

Unfortunately, CPU frequency scaling can currently only be monitored on Linux machines that have support in the kernel. It can however, support the several generations of frequency scaling interfaces in the kernel.

The recent CPUs have a feature which let them scale their operating frequency (changing a voltage power supply input) according to the system/user needs. This way, when the entire processor resources are not needed, the system can greatly reduces the overall power consumption, lowering temperatures and fan speed ;) This post addresses the frequency scaling setup in Linux: enjoy

Interesting blog about how environmentally friendly Google is, and whether painting the background black instead of white would save electricity and help save the planet.

IBM is embarking on a huge energy-conservation project to consolidate about 3,900 of its own servers reducing power use by about 80 percent and saving US$250 million on electricity, support and software over five years. Under the project, IBM will replace 3,900 smaller servers with 30 IBM System z9 mainframes running Linux and virtualization software.

"The Linux Foundation has formed a Green Linux initiative to focus on reducing the open source operating system's power consumption."

Installing Linux is trivial nowadays. You just need to download ISO image, burn it on CD/DVD and reboot the machine. But, what if… the computer doesn’t have a CD drive? Well, don’t worry. In such case you can install Linux directly through the net. This is called PXE and in this article you’ll learn how to use it.

Over the past few months, the concept of green computing has become all the rage. But the undeniable fact is that often times with this low impact approach to computing, we end up sacrificing actual computing power, which makes this a tough sell for many. Frankly, to me it just feels like a marketing ploy. Could this perception be felt by others as well?

Recently Products Editor, James Gray, caught up with IBM's Inna Kuznetsova, Worldwide Director for IBM's Linux strategy. They discuss IBM's Big Green Linux intiative and IBM's own power-saving move to Linux on its own data center.

Virtualisation is a technology that can work wonders: provide a testing environment, enhance your processing power, consolidate your computing resources, decrease running costs, preserve legacy apps and more! Here’s how virtualisation can benefit you and why the Linux route really beats out the competition.
