Neutron Science and Supercomputing Come Together at Oak Ridge National Lab

Dec 4, 2012 |

<img style=”float: left;” src=”” alt=”” width=”93″ height=”89″ />As the data sets generated by the increasingly powerful neutron scattering instruments at ORNL’s Spallation Neutron Source (SNS) grow ever more massive, the facility’s users require significant advances in data reduction and analysis tools. To meet the challenge, SNS data specialists have teamed with ORNL’s Computing and Computational Sciences Directorate.

Software Tools Will Need Refresh for ORNL’s Titan Supercomputer

Nov 21, 2011 |

In 2012 Oak Ridge National Laboratory will initiate a major upgrade of Jaguar using the latest CPUs and GPUs, resulting in a new 10-20 petaflop supercomputer called Titan. Such a system will require the a concerted effort of many teams at ORNL, including the Application Performance Tools Group, headed by Richard Graham. In this interview he describes the challenges of bringing all the supercomputing software tools up to speed for the new system.

NOAA-ORNL Climate Research Collaboration Sets Lofty Goals for New Supercomputer

Jul 26, 2010 |

A year ago, NOAA and DOE signed an agreement calling for closer cooperation between NOAA and Oak Ridge National Laboratory. Jim Rogers, director of operations for the National Center for Computational Sciences at ORNL, discusses the agreement and the goals for the Climate Modeling and Research System (CMRS), the initial supercomputer chosen for the collaborative work.

Supercomputers Put Charge into Battery Research

May 12, 2010 |

The idea of using lithium-air batteries to power electric cars has been around since the 1990s, but the last few years has seen a big upsurge in interest for this technology. Oil supply concerns, global climate change, and a general discontent with the internal combustion engine are driving the search for more robust batteries, and lithium-air is at the top of the list.
