Supercomputing Powers Clean Wind Energy

Dr. Lawrence Cheung and the team from GE Global Research are maximizing the power production of clean energy wind farms. As a clean, renewable energy source, wind power is unbeatable. Research studies show that wind, harnessed effectively, could meet all the world’s energy demands. But a gap still exists between potential and reality ... a gap that Lawrence Cheung and GE Global Research are working on closing. “We’re trying to understand what the wind is doing around the turbines, why it might not be getting enough power here or why it’s not efficient there." Dr. Cheung is a lead mechanical engineer at GE Global Research Center’s Aerothermal discipline. There, he studies wind and noise — elements critical to the design of wind ... [ Read More ]

How the Met Office Solved a Weather Forecasting Runtime Scare

When the Met Office chose Cray to supply three large XC40 supercomputers, Cray’s CEO, Peter Ungaro, made a bold statement. He said, "You will be installing the largest operational systems in the world. There will be problems at scale that you won't have anticipated. Partnership with Cray will allow you to access our deep expertise and solve these problems." Recent ambitious upgrades to the Met Office's forecasting codes have meant we have been able to test this claim. Operational weather forecasting is unlike many other areas of science because it is critical that the computer models run to a strict time schedule. A forecast that takes too long to run isn’t available in time for customers to make decisions, and so is worthless. The Met ... [ Read More ]

Deep Learning at Scale with NERSC’s “Cori” Supercomputer

Cray is synonymous with large-scale computing. While this is by no means all we do, the research that leverages these large systems is interesting to examine as leading indicators of things to come in the broader community. This has been true for a long time in modeling and simulation, and we’re now beginning to see the same advances in the area of deep learning. For example, the Cray® XC™ “Cori” supercomputer at the National Energy Research Scientific Computing Center (NERSC) is an amazing system, sitting at #8 on the most recent Top500 list of the world’s fastest supercomputers. Of course, it’s the organization that surrounds Cori that enables the use of such technology. To this end and to help further the use of Cori for ... [ Read More ]

How HPC Can Help Tap the Power of Ocean Waves

“What’s amazing about ocean wave energy is the enormity of the resource sitting there,” says Ashkan Rafiee. “Whoever solves this riddle will make a huge impact on the world.” Dr. Rafiee is the hydrodynamics team leader for Carnegie Clean Energy — an Australian wave, solar and battery energy company well on its way to making wave power a reality. For the last decade, Carnegie has been developing a wave energy device that converts ocean swell into zero-emission, renewable power and desalinated freshwater. Dubbed “CETO,” the device is already in use off of Western Australia’s Garden Island, helping power the country’s largest naval base. But deploying wave energy technology at scale is another matter. “The potential is phenomenal,” says ... [ Read More ]

Cray’s New Urika-XC Suite: the Convergence of Supercomputing and Analytics

Cray today announced the launch of the Cray® Urika®-XC analytics software suite, which brings graph analytics, deep learning and robust big data analytics tools to the company’s flagship line of Cray® XC™ supercomputers. The Cray Urika-XC analytics software suite empowers data scientists to make breakthrough discoveries previously hidden within massive datasets, and achieve faster time to insight while leveraging the scale and performance of Cray XC supercomputers. With the Urika-XC software suite, analytics and artificial intelligence (AI) workloads can run alongside scientific modeling and simulations on XC supercomputers, eliminating costly and time-consuming movement of data between systems. Cray XC customers will be able to ... [ Read More ]
