New Degrees of Parallelism, Old Programming Planes

Aug 28, 2014 |

Exploiting the capabilities of HPC hardware is now more a matter of pushing into deeper levels of parallelism versus adding more cores or overclocking. What this means is that the time is right for a revolution in programming. The question is whether that revolution should be one that torches the landscape or that handles things Read more…

NERSC Launches Exascale Readiness Program with Intel, Cray

Aug 11, 2014 |

The National Energy Research Scientific Computing Center (NERSC) is collaborating with supercomputing vendors Intel and Cray to prepare for Cori, the Cray XC supercomputer scheduled to be deployed at NERSC in 2016. Named in honor of American biochemist Gerty Cori, the next-generation supercomputer will have a sustained performance that is at least ten times that Read more…

Exascale Resilience Turns a Corner

Jul 21, 2014 |

While advancing the field of HPC into the exascale era is beset by many obstacles, resiliency might be the most thorny of all. As the number of cores proliferate so too do the number of incorrect behaviors, threatening not just the operation of the machine, but the validity of the results as well. When you Read more…

Intel Gives Code Modernization Fresh Push

May 28, 2014 |

In the conversations leading up to exascale, one of the most frequently cited pain points is the need for massive software optimization and code modernization. But this isn’t just a relevant topic for the largest system operators at the supercomputing pinnacle. According to Intel’s General Manager of the Technical Computing Group, Charlie Wuischpard, there are Read more…

Altair Crash Tests New Xeon E7s

Mar 12, 2014 |

RADIOSS, one of the top structural analysis solvers in the industry, is used by auto companies like Ford and PSA in France to run car crash and other simulations to test safety and viability of a broad array of products. Like similar CAE codes, it is highly parallelized for top performance on large, powerful clusters–and Read more…

ARL Researchers Win Software Design Contest

Oct 16, 2014 |

Researchers from the U.S. Army Research Laboratory’s Computational and Information Sciences Directorate (CISD) – David Richie and James Ross – won first place in an international software contest for their work on emulators. Their submission, Cycle-Accurate 8080 Emulation Using an ARM11 Processor with Dynamic Binary Translation, addresses some of the programming challenges of next generation Read more…

NSF Promotes Data Science with $31M Award

Oct 1, 2014 |

The National Science Foundation (NSF) announced today some $31 million in awards for 17 innovative projects geared toward the promotion of data science and a robust data infrastructure. The National Science Foundation (NSF) seeks to improve the nation’s capacity in data science by investing in the development of infrastructure, making it easer to use data, Read more…

Deconstructing Moore’s Law’s Limits

Aug 18, 2014 |

For the past five decades, computers have progressed on a predictable trajectory, doubling in speed roughly every two years in tune with Gordon Moore’s oft-cited observation-turned-prophecy. Although semiconductor scaling continues to yield performance gains, many perceive a tipping point is nigh, where the cost-benefit analysis of further miniaturization breaks down. The latest researcher to weigh Read more…

Parallel Programming with OpenMP

Jul 31, 2014 |

One of the most important tools in the HPC programmer’s toolbox is OpenMP, a standard for expressing shared memory parallelism that was published in 1997. The current release, version 4.0, came out last November. In a recent video, Oracle’s OpenMP committee representative Nawal Copty explores some of the tool’s features and common pitfalls. Copty explains Read more…

Building Parallel Code with Hybrid Fortran

Jul 31, 2014 |

Over at the Typhoon Computing blog, Michel Müller addresses a topic that is top of mind to many HPC programmers: porting code to accelerators. Fortran programmers porting their code to GPGPUs (general purpose graphics processing units) have a new tool at their disposal, called Hybrid Fortran. Müller shows how this open source framework can enhance portability without sacrificing performance and maintainability. From the blog (editor’s note: the site Read more…
