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 much more than simple scaffolds for proteins and protective enclosures for cells. Read more…

Swiss Weather Forecasting Achieves 1.1km Resolution on ‘Piz Kesch’

Apr 1, 2016 |

After six months of tweaking – producing a 20 percent reduction in time-to-solution for weather forecasting – MeteoSwiss, the Federal Office of Meteorology and Climatology, today reported its next generation COSMO-1 forecasting system is now operational. COSMO-1 requires 20 times the computing power of COSMO-2 and runs on the hybrid CPU-GPU supercomputer, Piz Kesch, operated by the Swiss National Supercomputing Centre (CSCS) and custom built in collaboration with Cray and NVIDIA.

Total’s Pangea is now the Largest Industrial Supercomputer

Mar 29, 2016 |

Energy giant Total, long a prominent user of high performance computing, now has the largest supercomputer used by industry says the company. Total’s upgraded Pangea supercomputer from SGI delivers 6.7 petaflops, up from 2.3 petaflops, with expanded storage of 26 petabytes – enough to rank the system among the top ten of the Top500 list (2015).

Gonzalez Martirena of OSTP to Provide NSCI Update at HPC User Forum

Mar 29, 2016 |

With many questions still swirling around the National Strategic Computing Initiative (NSCI), IDC announced yesterday that Saul Gonzalez Martirena of the Office of Science and Technology Policy (OSTP) will provide an NSCI update at the HPC User Forum being held in two weeks.

Launched with great fanfare as a Presidential Executive Order last July, NSCI risks provoking selective ‘tone-deafness’ in the community as few added details have emerged since. Read more…

SGI UV 3000 Sets New Throughput Records

Mar 25, 2016 |

Today SGI’s Gabriel Broner announced that the company’s SGI UV 3000 system had set two new benchmarking records, demonstrating the machine’s advanced throughput prowess enabled by its shared memory architecture. The test machine — a 128 socket UV 3000 system equipped with 1,280 E5-4627 v3 2.60 GHz Xeon cores — was assessed using the industry-standardized SPECrate metrics (specifically SPECint_rate_base2006 and SPECfp_rate_base2006), which measure the throughput or rate of a machine carrying out a number of simultaneous tasks.

Mar 23, 2016 |

Earlier this week the Department of Energy’s National Energy Research Scientific Computing Center (NERSC) announced the five winners of the 2016 High Performance Computing (HPC) Achievement Awards. The awards recognize NERSC users who have demonstrated an innovative use of HPC resources to solve a scientific problem or whose work has had an exceptional impact on scientific understanding or society.

To encourage younger scientists who are using HPC in their research, NERSC also issued two early career awards. Read more…

Thomas Sterling: ‘Why We Want to be Part of OpenHPC’

Mar 18, 2016 |

The Indiana University Center for Research in Extreme Scale Technologies (CREST) has been part of the OpenHPC community effort since it was launched November 12, 2015. In a recent Q&A with OpenHPC, Professor Thomas Sterling, associate director and chief scientist of CREST, explains the basis for the partnership.

As the father of Beowulf clusters, developed in collaboration with Don Becker, Professor Sterling has experienced first-hand the singular power of community-wide involvement. Read more…
