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…

The Future of Accelerator Programming

Jan 9, 2014 |

Many of the latest supercomputers are based on accelerators, including the two fastest systems according to the 11/2013 TOP500 list. Accelerators are also becoming widespread in PCs and are even starting to appear in handheld devices, which will further boost the interest in accelerator programming. This broad adoption is the result of high performance, good Read more…

Adding MUSCLE to Multiscale Simulations

Dec 11, 2013 |

Multiscale models help understand phenomena with a wider scope or an increased level of detail. These models allow us to take the best from multiple worlds, for example by combining models with a fine-grained time or space resolution with models that capture systems over a large baseline. Classical examples of multiscale modeling include coupling atomistic 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…

The Portability Mandate

Jul 24, 2014 |

Argonne National Laboratory recently published several sessions from its Summer 2013 Extreme-Scale Computing program to YouTube. One of these is a lesson on combining performance and portability presented by Argonne Assistant Computational Scientist Jeff Hammond. For some reason the video image does not match the lecture, but you will find a link to Hammond’s slide deck here. Read more…

Parallel Computing Trends

Jul 22, 2014 |

One of the most pressing issues faced by the HPC community is how to go about attracting and training the next generation of HPC users. The staff at Argonne National Laboratory is tackling this challenge head on by holding an intensive summer school in extreme-scale computing. One of the highlights of the 2013 summer program was a Read more…

The Case for a Parallel Programming Alternative

Jul 2, 2014 |

Cray engineers have been working on a new parallel computing language, called Chapel. Aimed at large-scale parallel computing environments, Chapel was designed with a focus on productivity and accessibility. The project originated from the DARPA High Productivity Computing Systems (HPCS) program, which challenged HPC vendors to improve the productivity of high-end computing systems. To explain Read more…
