Milking the System for All It’s Worth

HP Seeks To Power Data Centers With Cow Manure.

The Times (UK) (5/23, Dey) reported Hewlett-Packard “is working on plans to power its data centres using energy generated from cow manure.” Company researchers “want to build computer warehouses on dairy farms where they would be hooked up to power plants fuelled by waste.” According to the article, “just one cow produces enough waste every day to power the televisions in three typical households. A large dairy farm, with about 10,000 cows, produces enough to run one of the firm’s typical data centres and meet the energy needs of the farmer, the HP scientists believe. If it works, the scheme could potentially solve two of the world’s looming environmental problems at a stroke:” the disposal of farm waste and large amounts of energy needed to cool off data centers.

Microprocessor Power Use

COMPUTER SCIENCE DEPARTMENT COLLOQUIUM

SPEAKER: Antonio González, Director, Intel Barcelona Research Center

TOPIC: Software to the Rescue of Power

DATE: Monday, May 10

TIME: 1:00 p.m.

PLACE: Olsson Hall Room 009

Abstract:  Power has become the main limiting factor for the scalability of microprocessors.  This limit is different for different systems (e.g. servers, desktops, laptops, MIDs, etc.), but in all of them it is already constraining the computing capabilities of the microprocessor.

Moore’s law will continue to provide us with the capability to integrate more devices in the same area, but the benefit of this ever increasing power density is jeopardized by the difficulties to dissipate the increased power it requires.  This clearly indicates that innovative solutions to reduce power are needed to harness the benefits of Moore’s law in order to keep delivering an increased performance to the end user.

To address this challenge, in this talk we will explore an approach based on implement microprocessors based on hardware/software co-design.

The main advantages of this approach are dramatic reductions in power and area without compromising performance when compared with traditional approaches.  This approach has other important advantages in the areas of scalability, reliability, legacy code and prototyping of new techniques that will be discussed.
