However we have to be careful if use human power for such activities because the calories we burn ultimately depend on our diet, which in the western world can have a large carbon footprint. An individual walking 2 km whose diet consists of steak and potatoes can leave a larger carbon footprint than driving an automobile the same distance. Thanks to John Krienke for this pointer.

In fact, to demonstrate how low the energy requirements of a supercomputer could be, he enlisted members of the university's bicycle team to power it with their pedaling. The demonstration, captured in the video below, shows a group of stationary bicyclists on one side of the room and a monitor displaying a glacial model on the other side. "This system--with a ridiculously small amount of power--was still doing world-class calculations," said James Bailey, marketing director for SiCortex <http://sicortex.com/> , the company that makes the brand of supercomputer Dickens purchased. The Search for the Right Supercomputer Dickens's search for a computer wasn't quick. It began when he received a $200,000 grant in 2007 from the National Science Foundation to purchase a supercomputer upon which to run the Scientific Grid Portal for accessing his university's computing resources. Dickens spent a year researching what system to buy. He wanted to get a supercomputer that wouldn't require dedicated resources to maintain and that would fit within his relatively modest hardware budget. "It takes a lot to put another supercomputer into the current facility. I didn't want to do that," he said. "I didn't want to worry about how to pay for maintenance." Plus, the institution was pushing to make the campuses as green as possible, and a traditional supercomputer purchase wouldn't necessarily satisfy that goal [.] ------------------------------------- To subscribe or unsubscribe send e-mail to [email protected] These news items and comments are mine alone and do not necessarily reflect those of the CANARIE board or management. ------ [email protected] [email protected] http://billstarnaud.blogspot.com/ ------=_NextPart_000_02D5_01C98080.CA558020 Content-Type: text/html;
