Cluster Lifecycle Management: The Final Wave

Nov 11, 2014 |

In the previous Cluster Lifecycle Management column, I described the steps your organization should take to develop an HPC cluster design that meets your application needs while providing a positive return on investment. The next step is to use your design as the basis for choosing a vendor, or vendors, that can build the system Read more…

Our Series Continues: Considering Cluster Lifecycle Management

Oct 22, 2014 |

In the first cluster management column, I discussed the importance of performing a needs assessment to ensure that an organization implementing its first HPC cluster designs a system that fulfills the requirements of its users and ultimately provides a positive ROI for the enterprise. It’s important to keep in mind there are no one-size-fits-all solutions Read more…

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…

ESnet Deploys 100G Connectivity Across Atlantic

Oct 21, 2014 |

The Department of Energy’s (DOE’s) Energy Sciences Network, or ESnet, is gearing up to deploy four new high-speed transatlantic links with a total capacity of 340 gigabits-per-second, significantly boosting network speeds between US research sites and European facilities. The trans-Atlantic expansion adds four separate links connecting Boston, New York and Washington DC with Amsterdam, London Read more…

Is the City of the Future Finally Here?

Oct 21, 2014 |

Grid computing pioneer and big data visionary Charlie Catlett recently delivered a presentation on “Big Data and the Future of Cities” as part of the Argonne OutLoud series, hosted by Argonne National Laboratory. Catlett explores how emerging technologies in high-performance computing, embedded systems and data analytics can help mitigate some of the challenges associated with Read more…

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…
