IBM Puts 3D XPoint on Notice with 3 Bits/Cell PCM Breakthrough

May 18, 2016 |

IBM scientists have broken new ground in the development of a phase change memory technology (PCM) that puts a target on competing 3D XPoint technology from Intel and Micron. IBM successfully stored 3 bits per cell in a 64k-cell array that had been pre-cycled 1 million times and exposed to temperatures up to 75∘C. A paper describing the advance was presented this week at the IEEE International Memory Workshop in Paris. Phase-change memory is an up-and-coming non-volatile memory technology…

IDC Server Report: China Surges; IBM Power Strengthens; ARM Stumbles

Mar 11, 2016 |

Led by strong growth in China, the worldwide server market grew 5.2 percent to $15.3 billion in the fourth quarter of 2015, reported market watcher IDC this week. It was the seventh consecutive quarterly (year over year) growth. Notably the high-end of the server market, typically used in the HPC world, actually fell slightly (2.3 Read more…

IBM Power8 Outperforms x86 on Financial Benchmarks

Jun 9, 2015 |

If you’ve been waiting for a formal evaluation of the IBM Power8 architecture on common financial workloads, then look no further. According to results shared at the STAC Summit on June 4, an IBM Power8-based system server delivered more than twice the performance of the best-in-class x86 counterpart when running a set of standard financial industry benchmarks. Sumit Read more…

CPU Benchmarking: Haswell Versus POWER8

Jun 2, 2015 |

With OpenPOWER activity ramping up and IBM’s prominent role in the upcoming DOE machines Summit and Sierra, it’s a good time to look at how the IBM POWER CPU stacks up against the x86 Xeon Haswell CPU from Intel. Citing the compute-intensive nature of today’s financial applications, the acceleration specialists at Xcelerit sought to compare IBM’s powerhouse 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…

Cray Goes Back to the Future for Weather Forecasting

Feb 16, 2014 |

Weather forecasting has come a long way since June of 1977, when the European Centre for Medium Range Weather Forecasts (ECMWF) first contracted Cray to deliver one of its early Cray-1A systems across the pond. This was the first time a Cray found its way to the old country—an installation that set the stage for Read more…

IBM’s New Deal Captures Refocused HPC Strategy

Jan 29, 2014 |

It’s been quite a month of news for IBM, with the sale of its x86 business to Lenovo, followed by some intense questioning about what this means for their vision (and future) with HPC customers in academia and government in particular. And while some might call this the centerpiece of a shift in strategy, something Read more…
