CERN Researchers Explore x86 Alternatives

Oct 28, 2014 |

Energy consumption has become a constraining feature on the growth of computing systems, such that the industry has shifted its focus from pure performance to performance-per-watt. As a result, there is increased interest in newer chip architectures that emphasize energy efficiency. An international group of researchers with ties to CERN are especially concerned with the effect these power constraints Read more…

NVIDIA Boasts ‘Compelling HPC Solution’

Aug 20, 2014 |

Today marks the official release of the NVIDIA CUDA Toolkit version 6.5, which had previously been only available in its pre-release form. In a company blog post, NVIDIA’s Chief Technologist for GPU Computing Software Mark Harris covers the toolkit’s new features and improvements, including “support for CUDA Fortran in developer tools, user-defined callback functions in Read more…

Calxeda Closes Shop, Attempts to Restructure

Jan 6, 2014 |

On December 19, 2013, news broke that Austin-based ARM server chip pioneer Calxeda had ceased operations. This came as a surprise to many, especially supporters of ARM servers as an alternative to x86 dominance. EnterpriseTech‘s Timothy Prickett Morgan reports that despite the closing, Calxeda’s technology could live on, depending on who is willing to purchase Read more…

Alternatives to x86 for Physics Processing

Nov 11, 2013 |

The global distributed computing system known as the Worldwide LHC Computing Grid (WLCG) brings together resources from more than 150 computing centers in nearly 40 countries. Its mission is to store, distribute and analyze the 25 petabytes of data generated each year by the Large Hadron Collider (LHC), based out of the European Laboratory for Particle Physics (CERN) in Geneva, Switzerland.

HPC500 Q2 Call Recap

Aug 20, 2013 |

The HPC500 recently held its quarterly members only call and the topic was processor architectures. The group is comprised of industry leaders who steer the direction of HPC and bring HPC technology to bear on challenging problems in science, engineering, and business.

HPC to Ride ARM’s Lengthening Tail

Jul 18, 2013 |

These past couple of weeks we’ve been looking at what some new additions to the HPC processor arsenal mean for the future of supercomputing–both commercially and in research. While much of the attention has been on Xeon Phi and GPUs, the subject of ARM, now that 64-bit is on the horizon, is also worth…

Mapping the Energy Envelope of Multicore ARM Chips

Jun 6, 2013 |

Bigger is not always better in the world of supercomputing. While data scientists almost always desire more computational throughput, the key question is how best to deliver that: through traditional, power-hungry X64 processors, or through the cheap, low-power ARM processors that drive smartphones and tablets? The answer is not always clear.

ARM Muscles In on Intel’s Dominance in Datacenters

Jan 28, 2013 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/muscular_arm_159x.jpg” alt=”” width=”94″ height=”90″ />ARM chips are moving beyond the mobile device market and into the datacenter. A series of announcements in 2012 point to the enormous interest in the low-power chip architecture. So far, however, customers are just evaluating the business. 2013 will show how well ARM can compete…

Europeans Give Samsung CPU-GPU Chip a Go at Supercomputing

Nov 20, 2012 |

ARM-based CPU-GPU processor designed for mobile devices makes HPC debut.

Texas Instruments Puts ARM-DSP Processors Into Play for HPC

Nov 20, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/TI_ARM_DSP_SoC_small.bmp” alt=”” width=”90″ height=”94″ />NVIDIA, Intel and AMD were not the only chip vendors unveiling new HPC accelerators last week SC12. Texas Instruments (TI) announced a set of heterogeneous processors that they believe will offer among the best performance per watt in the industry. In this case, the chipmaker glued an ARM CPU and DSP together on the same die, offering a low-power SoC with an impressive number of FLOPS.
