AMD Refreshes Roadmap, Transitions Back to HPC

May 7, 2015 |

AMD revealed key elements of its multi-year strategy as part of its 2015 Financial Analyst Day event in New York on Wednesday. Out of the gate, CEO Lisa Su acknowledged the company’s recent challenges, pointing to a weak PC market and market share losses, before turning her attention to the game plan that AMD is Read more…

IEEE Group Seeks to Reinvent Computing as Scaling Stalls

May 6, 2015 |

Computer scientists worried about the end of computing as we know it have been banging heads for several years looking for ways to return to the historical exponential scaling of computer performance. What is needed, say the proponents of an initiative called “Rebooting Computing,” is nothing less than a radical rethinking of how computers are Read more…

Wrangler and Comet Reflect Changing NSF Priorities

May 4, 2015 |

“Early operations mode” describes the status of two NSF-funded systems that are on track to support a wider range of user than is traditionally served by elite-level supercomputing. Wrangler is the Texas Advanced Computing Center (TACC) system that we reported on last week, so now we turn our attention to Comet, the petascale supercomputer readying for launch at San Diego Read more…

Linux Widens HPC Goalposts

May 4, 2015 |

It is well known that the term “high performance computing” (HPC) originally describes the use of parallel processing for running advanced application programs efficiently, reliably and quickly. The term applies especially to systems that function above a teraflop or 10^12 floating-point operations per second, and is also often used as a synonym for supercomputing. Technically Read more…

Why TACC’s New Data ‘Wrangler’ Is a Big Deal

Apr 30, 2015 |

While there’s been a lot of activity around the coming crop of “exascale-relevant” supercomputers, the HPC landscape is also shifting to become more data-aware. Perhaps no system reflects this transition better than Wrangler, the I/O-optimized open science system from Dell and EMC that debuted earlier this month at the Texas Advanced Computing Center (TACC). In a presentation Read more…

First Use of HPC to Pick Vendors in Army Procurement Program

Apr 29, 2015 |

Over the next 25 to 40 years, the U.S. Army plans to replace its entire fleet of vertical lift helicopters, a project costing billions of taxpayer dollars. For the first time, HPC modeling was decisive in reducing the number of hopeful competing vendors – AVX Aircraft, Bell Helicopter, Karem Aircraft, and Sikorsky/Boeing – from four Read more…

NASA’s Earth Science Supercomputer Balloons to 3.3 Petaflops

Apr 29, 2015 |

In what is being called an unprecedented upgrade, the NASA Center for Climate Simulation (NCCS) is tripling the peak performance of its Discover supercomputer to more than 3.3 petaflops to power NASA’s Earth science modeling efforts. The open procurement process included the benchmarking of NCCS codes – notably the Goddard Earth Observing System Model, Version Read more…

New Models for Research, Part IV – Delivering Research as a Service

Apr 27, 2015 |

In the fourth of a four-part installation, Jay Etchings, director of operations for research computing and senior HPC architect at Arizona State University, traces the drivers that have led to the emergence of Research-as-a-Service as a viable model. As far back as the launch to the cloud with applications like Salesforce in 1999 and Amazon Web Services in Read more…

NERSC Invites Haswell-Based Cray XC40 Into Cori Fold

Apr 22, 2015 |

Nearly one year after the Department of Energy inked a $70 million contract for the exascale-relevant Cori system, news of a second, smaller system has come to light. In an interesting turn of events, the National Energy Research Scientific Computing Center (NERSC) revealed today that it will be acquiring a “Cori Phase 1” system, a 10-cabinet Cray XC40 machine Read more…

Application Readiness at the DOE, Part III: Argonne Ramps Up Early Science Program

Apr 20, 2015 |

In our third and final video 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), Tim Williams dives into the Early Science Program (ESP) being ramped up at the Argonne Leadership Computing Facility (ALCF). Williams, the ESP manager, noted the current Read more…
