Danes Take Back Fastest Data Transfer Title

Aug 6, 2014 |

The team that broke the terabit barrier in 2009 is at it again. This time the High-Speed Optical Communications (HSOC) team at the Technical University of Denmark accomplished a record-smashing 43 terabits per second (Tbps) transfer speed over a single optical fiber with just one laser transmitter. That’s equivalent to a transfer rate of around 5.4 Read more…

Is This the Exascale Breakthrough We’ve Been Waiting For?

Aug 6, 2014 |

An animated video, narrated by the inimitable Professor Heinz Wolff, popped up on YouTube last month, detailing a prototype optical processor with some remarkable claims. The company behind the effort, UK-based startup Optalysys, says it is on track to deliver exascale levels of processing power on a standard-sized desktop computer within the next few years.

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…

DOE to Fund Exascale Resilience Research

Jul 30, 2014 |

As the calendar counts down to the first exascale supercomputer, efforts to resolve the steep technological challenges are increasing in number and urgency. Among the many obstacles inhibiting extreme-scale computing platforms – resilience is one of the most significant. As systems approach billion-way parallelism, the proliferation of errors at current rates just won’t do. In Read more…

Wave Energy Gains Momentum with HPC

Jul 30, 2014 |

You are no doubt familiar with solar parks and wind farms, but what about wave farms? With the disastrous implications of climate change pushing government and industry to pursue greener energy sources, there has been increased interest in solar and wind power, but another renewable is also on the rise: wave energy. Wave farms, also called wave Read more…

Tech Titans Pledge Free Cycles for Climate Change Research

Jul 29, 2014 |

Amazon, Microsoft and IBM are promising to provide free virtual supercomputing and cloud resources to support the US government’s Climate Action Plan and Climate Data Initiative program. The initiatives, which were unveiled earlier today, coincide with a report from the Council of Economic Advisers that explores the economic consequences of delaying action to stem climate Read more…

SC14 Technical Program Preview

Jul 29, 2014 |

July has been rather quiet in the HPC space, but what better time to start looking ahead and preparing for the busy fall ahead, including the preeminent annual HPC event: SC14. Attendees won’t flock to this event until November 16, but SC planners are busy getting everything into place, including the core event offering: the Read more…

Simulations Link Common Brain Disorders

Jul 28, 2014 |

When a coalition of leading researchers from the US and the EU wanted to study brain disorders that involve disturbances of dopaminergic signaling, they turned to the powerful supercomputing resources of the Texas Advanced Computing Center. Using the Extreme Science and Engineering Discovery Environment (XSEDE) cyberinfrastructure and TACC’s Stampede supercomputer, the research team uncovered a link Read more…
