Processor Diversity on the Rise, Reports Intersect360

Nov 12, 2015 |

Intel x86 processors continue to dominate HPC servers while the number of cores per processor also keeps rising, perhaps no surprises there. Also somewhat anticipated, the amount of memory per core, per processor, and per node is rising. These are the top line results of Intersect360 Research’s latest HPC sites survey on processor use. A Read more…

Defining Scalable OS Requirements for Exascale and Beyond

Oct 5, 2015 |

Over the past couple of decades two primary trends have driven system software for supercomputers to become significantly more complex. First, hardware has become more complex. Massive inter-node parallelism (100,000+ nodes), increasingly large intra-node parallelism (100+ hardware threads), wider vector units, accelerators, coprocessors, etc., have required that system software play a larger role in delivering Read more…

IBM, NVIDIA and Mellanox Launch Design Center for HPC

Jul 2, 2015 |

Today’s launch by IBM, NVIDIA, and Mellanox of a new POWER Acceleration and Design Center in Montpellier, France, ratchets up their campaign to attract a wider developer community to the OpenPOWER platform and their efforts to build momentum for the march into the Intel-dominated HPC landscape. The Montpellier-based center is the second of its kind, Read more…

Is IBM Getting Openness Right? Yes, Says GM Doug Balog

Jun 29, 2015 |

The annual Red Hat Summit, held in Boston last week, is something of revival tent for open source where the pulpits are plentiful and so are smiling believers. Indeed it’s hard to dispute the powerful innovation springing from open source. The RH Summit, which started 11 years ago as a modest celebration of open source Read more…

Tracking the Trajectory to Exascale and Beyond

Jun 8, 2015 |

The future of high performance computing is now being defined both in how it will be achieved and in the ways in which it will impact diverse fields in science and technology, industry and commerce, and security and society. At this time there is great expectation but much uncertainty creating a climate of opportunity, challenge, Read more…

Fujitsu Targets 100 Petaflops Supercomputing

Aug 12, 2014 |

On Monday at the Hot Chips 26 conference, Fujitsu revealed details about its upcoming SPARC64 XIfx chips, which the company is counting on to reach the 100-petaflops barrier and revitalize its HPC game. Of the top 10 fastest supercomputers on the current TOP500 list, only one is a Fujitsu system. But with the new 32-core Read more…

Alternatives to x86 for Physics Processing

Nov 11, 2013 |

The global distributed computing system known as the Worldwide LHC Computing Grid (WLCG) brings together resources from more than 150 computing centers in nearly 40 countries. Its mission is to store, distribute and analyze the 25 petabytes of data generated each year by the Large Hadron Collider (LHC), based out of the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland.

New Hope for Graphene-based Logic Circuits

Sep 6, 2013 |

As an excellent conductor of heat and electricity, graphene is a promising electronics substrate, but it can’t be switched on and off like silicon can. With no solution in sight, a team of UC Riverside researchers has taken a completely new approach.

Mapping the Energy Envelope of Multicore ARM Chips

Jun 6, 2013 |

Bigger is not always better in the world of supercomputing. While data scientists almost always desire more computational throughput, the key question is how best to deliver that: through traditional, power-hungry X64 processors, or through the cheap, low-power ARM processors that drive smartphones and tablets? The answer is not always clear.

Supercomputing Vet Champions Quantum Cause

May 13, 2013 |

Supercomputing veteran, Bo Ewald, has been neck-deep in bleeding edge system development since his twelve-year stint at Cray Research back in the mid-1980s, which was followed by his tenure at large organizations like SGI and startups, including Scale Eight Corporation and Linux Networx. He has put his weight behind quantum company….
