The Weekly Top Five

Apr 14, 2011 |

The Weekly Top Five features the five biggest HPC stories of the week, condensed for your reading pleasure. This week, we cover Bull’s third petascale computing contract; IBM’s new POWER7 servers, the first hybrid spintronics computer chips, Bull and Whamcloud’s beefed-up Lustre support; and Tilera’s latest manycore development tools.

Compilers and More: Exascale Programming Requirements

Apr 14, 2011 |

In his third column on programming for exascale systems, Michael Wolfe shares his views on what programming at the exascale level is likely to require, and how we can get there from where we are today. He explains that it will take some work, but it’s not a wholesale rewrite of 50 years of high performance expertise.

Compilers and More: Expose, Express, Exploit

Mar 28, 2011 |

In Michael Wolfe’s second column on programming for exascale systems, he underscores the importance of exposing parallelism at all levels of design, either explicitly in the program, or implicitly within the compiler. Wolfe calls on developers to express this parallelism, in a language and in the generated code, and to exploit the parallelism, efficiently and effectively, at runtime on the target machine. He reminds the community that the only reason to pursue parallelism is for higher performance.

Consortium Seeks to “Advance” Multicore Future

Mar 25, 2011 |

ADVANCE Project explores new programming paradigms for multicore hardware.

Compilers and More: Programming at Exascale

Mar 8, 2011 |

There are at least two ways exascale computing can go, as exemplified by the top two systems on the latest TOP500 list: Tianhe-1A and Jaguar. The Chinese Tianhe-1A uses 14,000 Intel multicore processors with 7,000 NVIDIA Fermi GPUs as compute accelerators, whereas the American Jaguar Cray XT-5 uses 35,000 AMD 6-core processors.

TC Labs, a portal at MSDN DevLabs, provides developers with early access to Microsoft Technical Computing software.

Intel Charts Its Multicore and Manycore Future for HPC

Dec 1, 2010 |

As the high performance computing community hurtles toward the exaflop milestone, it has become clear that the natural evolution of multicore x86 CPUs won’t get the industry very far toward that goal. Manycore GPGPUs, on the other hand, do appear to be a viable path to exascale computing. So where does that leave GPU-less Intel?
