Plug-and-play multi-core voltage regulator could lead to 'smarter' smartphones, slimmer laptops and energy-friendly data centers

  • PDF
TechAndComputer (Feb. 28, 2011) — There was a time when a laptop could weigh 10 pounds and still sell -- a time when a cell phone was larger than a pocket -- and a time when an iPod only played music.

Today's consumers expect mobile devices that are increasingly small, yet ever-more powerful. All the bells and whistles, however, suck up energy, and a phone that lasts only 4 hours because it's also a GPS device is only so much use.

To promote energy-efficient multitasking, Harvard graduate student Wonyoung Kim has developed and demonstrated a new device with the potential to reduce the power usage of modern processing chips.

The advance could allow the creation of "smarter" smartphones, slimmer laptops, and more...

Reconfigurable supercomputing outperforms rivals in important science applications

  • PDF
TechAndComputer (Feb. 15, 2011) — University of Florida researchers say their supercomputer, named Novo-G, is the world's fastest reconfigurable supercomputer and is able to perform some important science applications faster than the Chinese supercomputer touted as the world's most powerful.

In November, the TOP500 list of the world's most powerful supercomputers, for the first time ever, named the Chinese Tianhe-1A system at the National...

Girls' interest in computing science piqued by making video games

  • PDF
TechAndComputer (Feb. 9, 2011) — A joint research project between the University of Alberta's Faculty of Education and the Department of Computing Science has found that, for high-school girls, the fun is in making video games, not just playing them.

Computing science professor Duane Szafron and fellow U of A researchers Mike Carbonaro, Jonathan Schaeffer and Maria Cutumisu say that women in computing science are rare, but their study shows that...

New device may revolutionize computer memory

  • PDF
TechAndComputer (Jan. 22, 2011) — Researchers from North Carolina State University have developed a new device that represents a significant advance for computer memory, making large-scale "server farms" more energy efficient and allowing computers to start more quickly.

Traditionally, there are two types of computer memory devices. Slow memory devices are used in persistent data storage technologies such as flash drives. They allow us to save...

Fruit fly nervous system provides new solution to fundamental computer network problem

  • PDF
TechAndComputer (Jan. 14, 2011) — The fruit fly has evolved a method for arranging the tiny, hair-like structures it uses to feel and hear the world that's so efficient a team of scientists in Israel and at Carnegie Mellon University says it could be used to more effectively deploy wireless sensor networks and other distributed computing applications.

With a minimum of communication and without advance knowledge of how they are connected with...
