Titan Helps Shed Light on Membrane Lipids’ Multiple Roles

Apr 4, 2016 |

Lipid molecules are schizophrenic. One end likes to hang out with a charged crowd (think water); the other prefers neutral neighbors (think fats). Most of us remember those funky illustrations of the bilayer lipid membrane structure that encloses animal cells from high school biology. Recently, Titan supercomputer was used to show cell membranes may be 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…

Application Readiness at the DOE, Part II: NERSC Preps for Cori

Apr 17, 2015 |

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…

Hybrid Test Clusters Forge Path to ‘Summit’

Mar 12, 2015 |

The Department of Energy (DOE) pre-exascale supercomputer Summit is not scheduled to go live until early 2018, yet support staff at the Oak Ridge Leadership Computing Facility (OLCF) have been preparing for Summit’s arrival since the contract was announced last November. The degree of planning is only natural considering the expense and resources involved in standing 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…

Titan Enables Next-Gen Nuclear Models

Jun 5, 2014 |

One of the main research areas for the Titan supercomputer, the elite Cray system installed at Oak Ridge Leadership Computing Facility, is energy, and in particular nuclear energy. At this point, about 20 percent of America’s energy is produced by nuclear power. Many experts say that increasing this percentage is key to meeting our nation’s growing Read more…

Titan Moves Full Steam Ahead

Jun 2, 2014 |

News being what it is, there’s a tendency to focus on what went wrong rather than what went right, but according to an update from the Oak Ridge Leadership Computing Facility, the early glitches associated with their Cray XK7 “Titan” system have been ironed out. Representatives with OLCF say that Titan “has overcome a challenging launch and Read more…

GPUs Speed Early Science Apps

Jan 6, 2014 |

Researchers working with the Oak Ridge Leadership Computing Facility’s (OLCF’s) Titan supercomputer are making the most of the system’s hybrid design, which pairs traditional CPUs with highly-parallel GPUs. As the fastest computer in the United States, Titan has a max theoretical speed of 27 petaflops, but as a recent OLCF article points out, “Titan is Read more…
