Washington State University has developed a wireless network on a computer chip that could reduce energy consumption at huge data farms by as much as 20 percent.
Researchers led by Partha Pande, a computer engineering professor in the School of Electrical Engineering and Computer Science, have filed two patents on their wireless multicore chip design, which could also speed up data processing. The team, which includes associate professors Deukhyoun Heo and Benjamin Belzer, has a paper on their work in the May issue of ACM Journal on Emerging Technologies in Computing Systems and is building a prototype.
While portable devices have gone efficiently wireless, the data farms that provide instant availability to text messages, video downloads and more still use conventional metal wires on computer chips. These are incredibly wasteful for relatively long-range data exchange.
With ever growing amounts of data, sustainable computing has become of increasing interest to researchers, industry leaders and the public. As much as 99 percent of the energy for huge data warehouses is lost between the power plant and a customer’s iPhone, according to “Reinventing Fire,” a book by Amory Lovins and the Rocky Mountain Institute. One data center can consume enough electricity to power a medium-sized town; in 2010, there were more than 2,000 of them in the U.S., according to the New York Times.
