Trans-Continental InfiniBand Charts Exascale Course

Feb 3, 2015 |

Many nations are racing to cross the exascale computing finish line by roughly 2020. Yet the challenges are such that establishing useful exascale computers some 50-100 times faster than today’s leadership machines requires the coordinated efforts of a vast array of stakeholders. At Supercomputing 2014 (SC14), an industry collaboration called InfiniCortex launched with the goal Read more…

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…

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…
