GraphLab Raises $6.75M For Data Analysis Used In Consumer Recommendation Services

GraphLab, the open-source distributed database, has received $6.75 million from Madrona Venture Group and NEA for its machine learning technology used to analyze data graphs for recommendation engines. Developed five years ago at Carnegie Mellon University five years ago, the open-source data analysis platform takes semi-structured data that describe relationships between people, web traffic, product purchases and other data. It then analyzes that data for services to provide online recommendations. Graph databases, similar to Graphlab, have increased in use as more data needs correlating to better understand its meaning. Wikiepdia describes graph database in the context of graph theory. It applies mathematical structures “used to model pairwise relations between objects. A graph in this context is made up of vertices or nodes and lines called edges that connect them.” It’s the ability to make the connections between billions of nodes and lines that forms the basis for making recommendations. ...

Sequoia Supercomputer Sets Record With 'Time Warp'

Nerval's Lobster writes "The 'Sequoia' Blue Gene/Q supercomputer at the Lawrence Livermore National Laboratory (LLNL) has topped a new HPC record, helped along by a new 'Time Warp' protocol and benchmark that detects parallelism and automatically improves performance as the system scales out to more cores. Scientists at the Rensselaer Polytechnic Institute and LLNL said Sequoia topped 504 billion events per second, breaking the previous record of 12.2 billion events per second set in 2009. The scientists believe that such performance enables them to reach so-called "planetary"-scale calculations, enough to factor in all 7 billion people in the world, or the billions of hosts found on the Internet. 'We are reaching an interesting transition point where our simulation capability is limited more by our ability to develop, maintain, and validate models of complex systems than by our ability to execute them in a timely manner,' Chris Carothers, director of the Computational Center for Nanotechnology ...

Study: Limiting Bidding On Spectrum Could Cost Billions

itwbennett writes "According to a study (PDF) by the Georgetown Center for Business and Public Policy, restricting the ability of Verizon Wireless and AT&T to bid in upcoming spectrum auctions would drive down the bidding during the auction, and could cost the U.S. treasury as much as $12 billion. Even a partial restriction of bids by Verizon and AT&T could have a significant impact on auction revenues, said Douglas Holtz-Eakin, a co-author of the Georgetown study. Matt Wood, policy director at digital rights group Free Press, fired back, saying 'No one is talking about completely barring AT&T and Verizon from the incentive auction. Sensible people are talking about making sure that more than two companies have a chance at obtaining spectrum. The fact that these duopolists hired economists to parrot the companies' own talking points isn't really that newsworthy.'"
