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…

BAE Systems Hones HPC Strategy

Jul 16, 2014 |

High-performance computing is vitally important to the mission of BAE Systems, one of the largest defense, aerospace, and security contractors in the world. As a high-tech manufacturer, BAE Systems relies on simulation and modeling software to design and build its products. The group responsible for identifying and developing this technology inside BAE Systems is called Read more…

Programmability Matters

Jun 30, 2014 |

While discussions of HPC architectures have long centered on performance gains, that is not the only measure of success, according to Petteri Laakso of Vector Fabrics. Spurred by ever-proliferating core counts, programmability is taking on new prominence. Vector Fabrics is a Netherlands-based company that specializes in multicore software parallelization tools, so programmability is high on Read more…

Student Supercomputing Competition Embraces GPU-Power

Jun 26, 2014 |

The third and final day of ISC14 concluded with a ceremony honoring one of the week’s most popular events, the Student Cluster Challenge. Taking home first prize for the second straight year was the team from the Centre for HPC (CHPC) in South Africa. Jointly sponsored by Dell, NVIDIA and Mellanox, the undergraduate team relied on Read more…

Titan Enables Next-Gen Nuclear Models

Jun 5, 2014 |

One of the main research areas for the Titan supercomputer, the elite Cray system installed at Oak Ridge Leadership Computing Facility, is energy, and in particular nuclear energy. At this point, about 20 percent of America’s energy is produced by nuclear power. Many experts say that increasing this percentage is key to meeting our nation’s growing Read more…

Seismic Imaging at the DEEP End

Jun 3, 2014 |

With exascale presenting a much larger challenge than previous exponential computing markers, an integrated, collaborative approach is all the more necessary. While concerted funding efforts for extreme-scale computing came a bit later than many had hoped, there are several international efforts afoot currently, including the European project, DEEP. DEEP, which stands for Dynamical ExaScale Entry Read more…

Accelerating the Cloud with GPUs

May 16, 2014 |

If you were to come up with a list of transformative technologies to hit HPC in the last decade, cloud services and general-purpose GPUs would rank pretty high. While the idea of using virtual machines to run technical computing workloads was anathema to some, at least initially, the benefits were hard to argue with. Ease Read more…

Linear Solver Library Grows Up

May 16, 2014 |

NVIDIA’s AmgX is a linear solver library for large-scale industrial applications that entered beta production in January. Since then the software has matured, and Joe Eaton, lead for the AmgX product team at NVIDIA, wrote all about it in a recent blog. Eaton explains that V1.0 comes with classical AMG multi-GPU support and greatly improved Read more…

NVIDIA Enables Device-Level Supercomputing

May 1, 2014 |

The Jetson TK1 development kit is now shipping. Order what GPU maker NVIDIA calls the “first mobile embedded supercomputer” and you’ll get a board with the same core technology that’s in use by many of the world’s fastest supercomputers, including the top US system, Titan. You’ll also receive an AC adapter with power cord, a Read more…

Titan Captures Liquid-Crystal Film Complexity

Apr 14, 2014 |

Liquid-crystal displays (familiar to most as LCDs) rely on the light modulating properties of liquid crystals to bring images to life on a wide variety of screens. From computer monitors to televisions to instrumental panels and signage, LCDs are a pervasive element of modern life. LCDs employ high-tech films, which must be both thin and Read more…
