XPRESS Route to Exascale

Feb 28, 2013 |

<img src=”http://media2.hpcwire.com/hpcwire/abstract_future_150x.jpg” alt=”” width=”95″ height=”83″ />The Center for Research in Extreme Scale Computing (CREST) at Indiana University just got a $1.1 million grant to help further the move to exascale computing. Director Thomas Sterling is using some of the money to bolster UI’s research into highly parallel processing for HPC. He talks to HPCwire about his plans.

Intel Adds Programming Support for Latest Silicon

NVIDIA Pokes Holes in Intel’s Manycore Story

Apr 3, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/knights_corner_small.JPG” alt=”” width=”105″ height=”87″ />As NVIDIA’s upcoming Kepler-grade Tesla GPU prepares to do battle with Intel’s Knight Corner, the companies are busy formulating their respective HPC accelerator stories. While NVIDIA has enjoyed the advantage of actually having products in the field to talk about, Intel has managed to capture the attention of some fence-sitters with assurances of high programmability, simple recompiles, and transparent scalability for its Many Integrated Core (MIC) coprocessors. But according to NVIDIA’s Steve Scott, such promises ignore certain hard truths about how accelerator-based computing really works.

Intel Debuts New HPC Cluster Tool Suite

Nov 8, 2011 |

This week Intel unveiled its upmarket version of its Cluster Studio offering aimed at performance-minded MPI application developers. Called Cluster Studio XE, the jazzed-up developer suite adds Intel analysis tools to make it easier for programmers to optimize and tune codes for maximum performance. It also includes the latest compilers, runtimes, and MPI library to keep pace with the new developments in parallel programming.

QLogic Makes Case for Leaner, HPC-Centric InfiniBand

Jul 26, 2011 |

It was a bit of a surprise when QLogic beat out Mellanox as the interconnect vendor on the NNSA’s Tri-Lab Linux Capacity Cluster 2 contract. Not only was Mellanox the incumbent on the original Tri-Lab contract, but it is widely considered to have the more complete solution set for InfiniBand. Nevertheless, QLogic managed to win the day, and did so with somewhat unconventional technologies.
