Arista Poised for Ethernet Expansion

Jun 9, 2014 |

In the wake of the Arista Networks IPO news on Friday, there has been a great deal of conversation about what the future of software-defined networking will be going forward, not just for its obvious role in hyperscale datacenters, but in other IT segments as well, including HPC. To be clear, other than having a Read more…

SC13 Research Highlight: There Goes the Performance Neighborhood…

Nov 16, 2013 |

Message passing can take up a significant fraction of the run time for massively parallel science simulation codes. Consistently high message passing rates are required for these codes to deliver good performance. At Supercomputing 2013 (SC13), our research team from Lawrence Livermore (LLNL) will present the results of our study that show that run-to-run variability Read more…

Crash and Boom: Inside the 10GbE Adapter Market

Nov 12, 2013 |

It may be hard to believe, but we’re coming up on ten years with 10GbE as an adapter option for servers and workstations. In  2003 the first 10GbE network adapters based on a new breed of chips hit the market—and by 2006, the list had eventually grown to include nearly twenty (AdvancedIO, Broadcom, Chelsio, Intel, Read more…

Ethernet Alliance Chair Outlines HPC Roadmap

Oct 14, 2013 |

This week we can expect news from the Ethernet Alliance as it outlines its roadmap during the “Future of Ethernet” Technology Exploration Forum, which gets underway Tuesday and Wednesday. In addition to featuring a talk from the inventor of Ethernet, Bob Metcalfe, members will strike a new path toward 400 gigabit Ethernet (the working group Read more…

HPC Wales Creates Distributed Supercomputing Network

Aug 29, 2013 |

Businesses, schools, and other organizations in Wales now have access to HPC resources as a result of a new distributed supercomputing network unveiled by HPC Wales. The group says the network is the first of its kind in the UK, and will not only be a boon to Welsh researchers but will help with education too.

Short Takes

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…

Near-Linear Network Optimization Technique Proposed

Jan 9, 2014 |

A team of researchers from the Massachusetts Institute of Technology have devised a new framework for solving difficult network optimization problems. Mathematicians and computer scientists have long used the maximum flow problem, or “max flow,” to determine the most efficient path between points on a network, but as networks grow ever-more complex, solving the series Read more…

GPUs Ease Network Monitoring Chore

Dec 2, 2013 |

Accelerators, like NVIDIA Tesla GPUs and Intel Xeon Phi coprocessors, made a big splash this year at SC13 as these highly parallel number-crunchers carved out a significant presence on both the TOP500 and Green500 charts, but there’s another promising use for accelerators, according to Fermilab researcher Wenji Wu: network monitoring. Traditional network analysis tools have Read more…

Tiny Laser Transmits Data at Record Speeds

Nov 8, 2013 |

In the age of big data and cloud computing, fast and accurate data transfer is more important than ever. University of Illinois scientists address the network bottleneck. Scientists at the University of Illinois have figured out a way to transmit error-free data over fiber optic networks at 40 gigabits per second, a US record according Read more…

The Show Goes On…

Oct 10, 2013 |

SC13, the annual Supercomputing Conference, is set to take place next month, November 17-22, in Denver, Colorado. Because the annual event draws much of its attendee base from government agencies and national labs, the show’s organizers want to assure attendees that it will go on as planned regardless of how the government shutdown proceeds. SC13 Read more…
