Video: Present and Future Leadership Computers at OLCF

olcf

In this video from the 2015 OLCF User Meeting, Buddy Bland from Oak Ridge presents: Present and Future Leadership Computers at OLCF. “As the home of Titan, the fastest supercomputer in the USA, OLCF has an exciting future ahead with the 2017 deployment of the Summit supercomputer. Summit will deliver more than five times the computational performance of Titan’s 18,688 nodes, using only approximately 3,400 nodes when it arrives in 2017.”

GENCI to Collaborate with IBM in Race to Exascale

world

Today GENCI announced a collaboration with IBM aimed at speeding up the path to exascale computing. “The collaboration, planned to run for at least 18 months, focuses on readying complex scientific applications for systems under development expected to achieve more than 100 petaflops, a solid step forward on the path to exascale. Working closely with supercomputing experts from IBM, GENCI will have access to some of the most advanced high performance computing technologies stemming from the rapidly expanding OpenPOWER ecosystem.”

Video: Stunning Simulation Shows Comet in the Solar Wind

In what has to be one of the most beautiful simulations I’ve ever seen, this video from the European Space Agency shows simulated interaction of solar winds with 67P/Churyumov-Gerasimenko, the famous comet targeted the Rosetta mission. “The simulated conditions represent those expected at 1.3 AU from the Sun, close to perihelion, where the comet is strongly active.”

NASA Charts Sea Level Rise

“Sea level rise is one of the most visible signatures of our changing climate, and rising seas have profound impacts on our nation, our economy and all of humanity,” said Michael Freilich, director of NASA’s Earth Science Division. “By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes.”

From Grand Challenges to Critical Workflows

Grand-Challenge-Blog-Part1

Geert Wenes writes in the Cray Blog that the next generation of Grand Challenges will focus on critical workflows for Exascale. “For every historical HPC grand challenge application, there is now a critical dependency on a series of other processing and analysis steps, data movement and communications that goes well beyond the pre- and post-processing of yore. It is iterative, sometimes synchronous (in situ) and generally more on an equal footing with the “main” application.”

China May Develop Two 100 Petaflop Machines Within a Year

“Within the next 12 months, China expects to be operating not one but two 100 Petaflop computers, each containing (different) Chinese-made processors, and both coming on stream about a year before the United States’ 100 Petaflop machines being developed under the Coral initiative. Ironically, the CPU for one machine appears very similar to a technology abandoned by the USA in 2007, and the US Government, through its export embargo, has encouraged China to develop its own accelerator for the other machine.”

SDSC Gets One-year Extension for Gordon Supercomputer

The National Science Foundation has awarded the San Diego Supercomputer Center (SDSC) a one-year extension to continue operating its Gordon supercomputer, providing continued access to the cluster for a wide range of researchers with data-intensive projects.

Pushing the Boundaries of Combustion Simulation with Mira

“Researchers at the U.S. Department of Energy’s Argonne National Laboratory will be testing the limits of computing horsepower this year with a new simulation project from the Virtual Engine Research Institute and Fuels Initiative (VERIFI) that will harness 60 million computer core hours to dispel those uncertainties and pave the way to more effective engine simulations.”

Video: Climate Change – Fact, Fiction, and What You Can Do

Doug Sisterson, Argonne

“Climate change – or as Doug Sisterson, research meteorologist at Argonne National Laboratory, prefers to call it, climate disruption – is probably the greatest challenge we face in modern society, yet many of us don’t fully understand the causes or the consequences. Washington Governor Jay Inslee famously stated: “We’re the first generation to feel the impact of climate change and the last generation that can do something about it.”

Titan Supercomputer Powers the Future of Forecasting
