First-year INCITE researchers headline strong 2016 in advance of 2017 call for proposals At the Oak Ridge Leadership Computing Facility (OLCF), we know that using a supercomputer can be challenging. Almost every year, a portion of our users are renewed for another allocation. Many of our regular users have spent decades honing their computing abilities to efficiently use the  fastest supercomputer in the United States for scientific research. However, experience is only one aspect of gaining access to our Titan supercomputer. Our center isn’t considered world-class purely on the basis of having a world-class machine. The OLCF has a robust training and tutorial program, available online, that can help new or prospective users learn how ... [ Read More ]

Intel Broadwell Xeon Debuts on Cray XC and CS Series Supercomputers

Broadwell-Feat-blog

Your next demanding compute challenge: Does it seem insurmountable? Need more cores? Higher base processor frequency? Faster memory? All of the above? Take a look at Cray’s integration of next-generation Intel® Xeon® E5-2600 v4 processors, previously codenamed “Broadwell.” The new processor enables theoretical peak performance boosts of up to 30 percent for new and existing Cray® XC™ series supercomputers and Cray® CS™ series cluster supercomputers. The Broadwell “new process technology tick” implementation is all about improving performance, delivering higher peak flops than previous-generation “new micro-architecture tock” Haswell Xeon processors. Built on Intel’s 14nm Grantley platform, the new device family offers configurations ... [ Read More ]

5 Predictions of Where Supercomputing is Heading in 2016

From new processor technologies to quantum computing, 2016 promises to be another exciting year for supercomputing. Here are five predictions as to how the industry will push ahead in 2016:    The year of progress in new processor technologies There are a number of exciting technologies we should see in 2016, and a leader will be Intel’s next-generation Xeon Phi coprocessor – a hybrid between an accelerator and general purpose processor. This new class of processors will have a large impact on the industry with its innovative design that combines a many-core architecture with general-purpose productivity. Cray, for example, will be delivering Intel Xeon Phi processors with some of our largest systems, including those going to Los ... [ Read More ]

Happy New Year! Check out some of the top blog posts from 2015: Why Do Better Forecasts Matter? Meteorologists have been striving to increase the accuracy of their work since the first weather forecasts were issued in the mid-19th century by pioneers such as Robert FitzRoy. In the 1950s and 1960s, the development of computers and observational technologies enabled forecast generation using the numerical weather prediction theories of Vilhelm Bjerknes and Lewis Fry Richardson. Today the numerical models that support our weather and climate forecasts are true “grand challenge” problems, requiring on the order of 10,000 billion (1016) mathematical operations and the exchange of 150 billion (1.5 x 1014) bytes of information to generate a ...

Can We Make Petabytes Useful?

TIdal-Wave

A recent article in Nature, “The Power of Petabytes”, by Michael Eisenstein, reviews how exponentially increasing life science data exceeds our present abilities to process and make sense of it. Even while continuing to grow unbounded, data sets are still often not yet large enough to draw convincing conclusions. Computation is one obvious problem. “The computation scales linearly with respect to the number of people,” says Marylyn Ritchie, a genomics researcher at Pennsylvania State University in State College. “But as you add more variables, it becomes exponential as you start to look at different combinations.” To efficiently harness growing computing resources, researchers will need to leverage scalable algorithmic approaches and ...
