Think of a computer so energy-efficient that it can last 75 times longer than today\u2019s systems. Researchers at Georgia Tech are helping the Defense Advanced Projects Research Agency (DARPA) develop such a computer as part of an initiative called Power Efficiency Revolution for Embedded Computing Technologies, or PERFECT.\u003C\/p\u003E\u003Cp\u003E\u201cThe program is looking at how do we come to a new paradigm of computing where running time isn\u2019t necessarily the constraint, but how much power and battery that we have available is really the new constraint,\u201d says \u003Ca href=\u0022http:\/\/www.cse.gatech.edu\/people\/david-bader\u0022 target=\u0022_blank\u0022\u003EDavid Bader\u003C\/a\u003E, executive director of high-performance computing at the School of Computational Science and Engineering.\u003C\/p\u003E\u003Cp\u003EIf the project is successful, it could result in computers far smaller and orders of magnitude more efficient than today\u2019s machines. It could also mean that the computer mounted tomorrow on an unmanned aircraft or ground vehicle, or even worn by a soldier would use less energy than a larger device, while still being as powerful.\u003C\/p\u003E\u003Cp\u003EGeorgia Tech\u2019s part in the DARPA-led PERFECT effort is called GRATEFUL, which stands for Graph Analysis Tackling power-Efficiency, Uncertainty and Locality. Headed by Bader and co-investigator \u003Ca href=\u0022http:\/\/www.cse.gatech.edu\/people\/edward-riedy\u0022 target=\u0022_blank\u0022\u003EJason Riedy\u003C\/a\u003E, GRATEFUL focuses on algorithms that would process vast stores of data and turn it into a graphical representation in the most energy-efficient way possible.\u003C\/p\u003E\u003Cp\u003EThe ultimate goal is to get an algorithmic framework that delivers supercomputer capabilities on a small, power-restricted platform.\u003C\/p\u003E\u003Cp\u003EOne approach to reducing power consumption is to reduce the level of data collection. For example, when looking for a needle in a haystack, you don\u2019t necessarily need to inspect every piece of hay. \u201cWhat we\u2019re looking at is collecting the minimal data necessary to make accurate decisions,\u201d Bader says.\u003C\/p\u003E\u003Cp\u003EFor now, the Tech team is applying GRATEFUL to social network analysis. But that same technology could also be used for any number of security applications, such as identifying hackers trying to break into a network. And, eventually, the technology developed under GRATEFUL could find its way onto smaller, more efficient computers in unmanned aerial vehicles or worn by soldiers.\u003C\/p\u003E\u003Cp\u003EThe team is currently one year into a potentially five-year effort. Bader says most of the work is still in the elementary stages, but the team is developing proofs of concept software. \u201cOur goal is to create architecture-independent software that can run across multiple hardware platforms and still perform extremely well,\u201d he says.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Many top defense technologies get their start in Tech\u2019s labs."}],"uid":"27255","created_gmt":"2014-07-03 11:53:35","changed_gmt":"2016-10-08 03:16:41","author":"Josie Giles","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2014-07-03T00:00:00-04:00","iso_date":"2014-07-03T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"272011":{"id":"272011","type":"image","title":"David Bader","body":null,"created":"1449244095","gmt_created":"2015-12-04 15:48:15","changed":"1475894961","gmt_changed":"2016-10-08 02:49:21","alt":"David Bader","file":{"fid":"198654","name":"david_bader_in_office.jpg","image_path":"\/sites\/default\/files\/images\/david_bader_in_office_0.jpg","image_full_path":"http:\/\/hg.gatech.edu\/\/sites\/default\/files\/images\/david_bader_in_office_0.jpg","mime":"image\/jpeg","size":5387690,"path_740":"http:\/\/hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/david_bader_in_office_0.jpg?itok=FODi6WVq"}},"306891":{"id":"306891","type":"image","title":"David A.
