Titan Simulation Reveals New Details of Fissioning Plutonium

Jul 26, 2016 |

In a first study of its kind, a team led by the University of Washington’s Aurel Bulgac captured the real-time dynamics of a fissioning plutonium-240 nucleus by simulating the process on the Titan supercomputer at the Oak Ridge Leadership Computing Facility (OLCF), a US Department of Energy (DOE) Office of Science User Facility. To create Read more…

ORNL Shows Off Titan on Periscope

Nov 5, 2015 |

If you need a reason to join the Periscope craze, how about getting an inside look at the fastest supercomputer in the United States? Today staff at the Oak Ridge Leadership Computing Facility (OLCF), the DOE Office of Science user facility at Oak Ridge National Laboratory (ORNL) took the Periscope audience on a tour of Titan, Read more…

Unlocking the Mysteries of Space

Jun 16, 2015 |

Some of the most powerful supercomputers in the world are helping NASA scientists reveal the mysteries of the universe. The intensive discovery process would not be possible without the modeling and simulation capabilities of high-performance computers, like Pleiades, which is located at the NASA Advanced Supercomputing (NAS) facility at Ames Research Center, and Titan, the fastest Read more…

In our second video feature from the HPC User Forum panel, “The Who-What-When of Getting Applications Ready to Run On, And Across, Office of Science Next-Gen Leadership Computing Systems,” we learn more about the goals and challenges associated with getting science applications ready for the coming crop of Department of Energy (DOE) supercomputers, which in addition to being five-to-seven times faster than Read more…

Summit Puts 13 Code Projects Into Readiness Program

Apr 15, 2015 |

When the Oak Ridge National Laboratory’s Summit supercomputer powers up in 2018, it will provide the Department of Energy (DOE) research community with 150 to 300 peak petaflops of computational performance. To extract the highest benefit from this multi-million dollar machine that will be five to ten times the capability of the current fastest US Read more…

Titan Advances Superconductivity Research

Nov 5, 2014 |

Once again, the Department of Energy’s Titan supercomputer has helped propel a scientific breakthrough with far-ranging implications. Researchers with Rutgers University have used the 27-petaflops supercomputer, a key resource of Oak Ridge National Laboratory (ORNL), to advance their understanding of the link between spin dynamics and superconductivity. As explained in this feature article from ORNL’s Read more…

Autotune Software Promotes Greener Buildings

Sep 23, 2014 |

A new software effort underway at Oak Ridge National Laboratory (ORNL) aims to make it quicker, easier and cheaper to model energy use of buildings. ORNL building researchers are developing software that will automatically calibrate models for simulating building energy use, thereby promoting greener design of residential and commercial buildings. The new “Autotune” calibration software Read more…

The Surprising Science Behind Everyday Products

Aug 27, 2014 |

One doesn’t normally associate their favorite shampoo or laundry detergent with science, let alone multi-million dollar supercomputers, but in today’s modern world many well-known consumer goods are the products of extensive R&D. By using large-scale computational modeling to facilitate advanced product design, manufacturers can improve customer satisfaction and minimize costly design flaws. A recent feature article on the Read more…

Tiny Titan Preps Students for Multicore Era

Jun 16, 2014 |

Supercomputing can be daunting to the uninitiated. A peek at the hardware, for example, with row after row of black boxes, reveals little of the exciting science that is being enabled by these ultra-fast computations. To help make the world of HPC a little less opaque, staff members at Oak Ridge National Labs (ORNL) created Read more…
