LANL Showcases Supercomputing History

Nov 12, 2014 |

Los Alamos National Laboratory is celebrating 100. Not 100 years, but 100 supercomputers. The center that is best known for its role supporting national security for the last seven decades is also widely hailed as a premier supercomputing site. “Computing power for our Laboratory’s national security mission is a huge part of our proud legacy, and Read more…

Breaking: Detailed Results from Today’s Top 500 Fastest Supercomputers List

Jun 23, 2014 |

Greetings from Germany and the International Supercomputing Conference (ISC14) where, as happens each year, the bi-annual list of the top 500 fastest supercomputers is unveiled. Usually, this happens with a great deal of fanfare and speculation over which machine will take the top position. However, this year, there is little surprise in the finding that Read more…

Evolving Exascale Applications Via Graphs

Apr 29, 2014 |

There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…

Supercomputing Targets Cleaner Combustion

Oct 1, 2013 |

A team of scientists and mathematicians at the DOE’s Lawrence Berkeley National Laboratory are using powerful NERSC supercomputers together with sophisticated algorithms to create cleaner combustion technologies.

NSA’s ‘Secret War on Encryption’ Exposed

Sep 9, 2013 |

Documents made public by former intelligence analyst Edward Snowden reveal that the National Security Agency (NSA) has thwarted or circumvented many of the privacy safeguards of the Internet as part of a highly classified program codenamed Bullrun…

ADEPT Emphasizes Energy-Efficient Parallelism

Aug 29, 2013 |

The EU-funded ADEPT project is exploring the energy-efficient use of parallel technologies by combining the talents of HPC and the embedded sector. The goal is to develop a tool for modeling and predicting the power and performance characteristics of parallel systems.

The Supercomputers of Wall Street: Friend or Foe?

Jul 30, 2013 |

Today’s Wall Street is run by quantitative analysts who write the algorithms that run on the supercomputers that make the actual trades, using super high speed network connections to exchanges. While the new system has unquestionably enriched some, the question becomes: Has it benefited the rest of us?

Linux Foundation Maps Top500 Run

Jul 30, 2013 |

This week the Linux Foundation released a special report about its role over the last twenty years of the Top500, pointing to some significant trends that helped it switch places with Unix (which once had a 96% share of the list) in roughly a one-decade timeframe. For instance, there are a few….

FhGFS Designed for Scalability, Flexibility in HPC Clusters

Jul 24, 2013 |

When researchers in Germany sat down nearly a decade ago to create a brand new parallel file system for HPC clusters, they had three goals: maximum scalability, maximum flexibility, and ease of use. What they came up with was the Fraunhofer Parallel File System (FhGFS), which is now in use on supercomputers.

Senator Says U.S. Congress Doesn’t ‘Get’ Supercomputers

Jul 18, 2013 |

Supercomputers are clearly important to the ability of the U.S. to compete on the global stage, but some members of Congress don’t understand that, Illinois Senator Dick Durbin said at the recent dedication of Mira, the IBM BlueGene/Q supercomputer installed last year at the Argonne National Laboratory in Illinois.
