This Week in HPC News

Jun 12, 2014 |

If middleware was the theme from last week, then this week is all about hardware, from networking/interconnects (Arista) to systems (HP) to storage (Panasas). Let’s look at little closer at this week’s top stories, starting with HP. HP’s rebooting of the Apollo brand this week was well received. This new family of high performance computing systems Read more…

What Power8 and OpenPOWER Might Mean for HPC

Apr 23, 2014 |

IBM is making a big play in hybrid computing, seeking to marry its POWER8 processors with various kinds of accelerators and high-speed networking and opening up its chip and system software through the OpenPOWER Foundation. At the Open Innovation Summit in San Francisco today, IBM and its foundation partners talked about how their collaboration would deliver Read more…

Top 500 Interconnect History Highlights Ethernet Trends

Nov 19, 2013 |

As we related earlier when the news of the Top 500 rankings broke this morning, this November’s SC list was a rather static one in terms of the top ten systems. While this isn’t entirely unexpected since it was not likely anyone would usurp China’s dominance and since there were no big processor movements in Read more…

LINPACK Creator Sheds Light on Emerging HPC Benchmark

Nov 18, 2013 |

Back in June during the International Supercomputing Conference (ISC), we discussed the need for a potential alternative to the current LINPACK benchmark, which is the sturdy yardstick by which supercomputing might is measured, with its creator, Dr. Jack Dongarra. At that time, he described a new benchmarking effort that is taking shape with the input 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…

NCKU Develops Switchless HPC Cluster

Dec 2, 2013 |

The National Cheng Kung University (NCKU) Supercomputing Research Center (RSC), based in Tainan City, Taiwan, has teamed up with Acer to build what it claims is the first ever switchless HPC cluster. The “CK-Star” computer, as it’s known, connects eight computational nodes without employing a switch control, exceeding previous efforts by Intel, according to the university. Read more…

DOE Funds Exascale Interconnect R&D

Nov 15, 2013 |

The Department of Energy (DOE) continues to prime the R&D pump for the next-generation of supercomputers, exascale machines 50 times more powerful than today’s leading number-crunchers. In order to bring this goal to fruition, the Department of Energy’s Office of Science together with the National Nuclear Security Administration (NNSA) have awarded $25.4 million in research Read more…

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…

Chip-Level Optical Interconnect Market Primed for Growth

Oct 16, 2013 |

Analyst firm Communications Industry Researchers (CIR) has released a new report covering the latest developments in optical interconnection at the chip level and the progress in this area that is being made by research teams throughout the world. With the current era of multicore processors and 3D chips, computing speeds are limited by how fast Read more…

Infinera, DANTE Achieve Guinness Record

Aug 30, 2013 |

Earlier this month, Infinera and DANTE (Delivery of Advanced Network Technology to Europe) set a record for fastest provisioning of long haul optical transmission capacity. In less than 20 minutes, the network specialists enabled enough capacity to support the simultaneous streaming of 1.6 million HD films in both directions.
