Intel Haswell-EX Server Sets STAC-A2 Performance Record

Sep 2, 2015 |

Intel has reasserted its prominence on a subset of financial benchmarks designed to evaluate platforms for the pricing and market risk analytics. More powerful Xeons — “Haswell-EX” E7-8890 v3 processors — combined with changes to the software stack enabled Intel to set a new speed record on the STAC-A2 benchmark for both warm and cold Read more…

COSMOS Team Achieves 100x Speedup on Cosmology Code

Aug 24, 2015 |

One of the most popular sessions at the Intel Developer Forum last week in San Francisco, and certainly one of the most exciting from an HPC perspective, brought together two of the world’s foremost experts in parallel programming to discuss current state-of-the-art methods for leveraging parallelism on processors and coprocessors. The speakers, Intel’s Jim Jeffers and Read more…

Moving Down the Path Toward Code Modernization

Aug 19, 2015 |

“Code modernization” is a hot topic. While it is widely understood that applications need to evolve with hardware, there is lot of attention to evaluating how to do that well. Savvy customers ask about both portability and performance portability. Because the time and expertise to do the work is scarce and the willingness to do Read more…

DOE Exascale Plan Gets Support with Caveats

Jul 28, 2015 |

The DOE and the National Nuclear Security Administration (NNSA) plan to develop and deploy exascale technology by 2023 received strong backing yesterday from an Advanced Scientific Computing Advisory Committee (ASCAC) sub-committee but with caveats in the form of seven recommendations for strengthening management of the Exascale Computing Initiative (ECI). Subcommittee chair, Dan Reed, vice president Read more…

The Necessary Marriage of Big Data with Exascale

Jun 29, 2015 |

Failure to incorporate big data computing insights into efforts to achieve exascale computing would be a critical mistake argue Daniel Reed and Jack Dongarra in their article, Exascale Computing and Big Data, published in the July issue of the Communications of the ACM journal. While scientific and big data computing have historically taken different development Read more…

Is IBM Getting Openness Right? Yes, Says GM Doug Balog

Jun 29, 2015 |

The annual Red Hat Summit, held in Boston last week, is something of revival tent for open source where the pulpits are plentiful and so are smiling believers. Indeed it’s hard to dispute the powerful innovation springing from open source. The RH Summit, which started 11 years ago as a modest celebration of open source Read more…

Blacklisting Doesn’t Slow Intel Investment in China

Apr 28, 2015 |

Intel may be barred from selling leading edge technology to China’s top supercomputer sites but it is nonetheless ramping up its high-end collaboration with China. On April 21st, Intel launched the first Intel Parallel Computing Center in China, a joint effort with the Chinese Academy of Sciences (CAS), with widely publicized ceremonies in China. “This Read more…

Compilers and More: The Past, Present and Future of Parallel Loops

Apr 6, 2015 |

Let’s talk about parallel loops. In parallel computing, we’ve been designing, describing, implementing and using parallel loops almost since the beginning. The advantage of parallel loops (over almost all other forms of parallelism) is that the parallelism scales up with the data set size or loop trip count (number of iterations). So what exactly is a parallel Read more…

Argonne’s Paul Messina on Training for Extreme-Scale

Mar 12, 2015 |

Paul Messina, director of science for the Argonne Leadership Computing Facility (ALCF), discusses the primary objectives, curriculum and importance of the Argonne Training Program on Extreme-Scale Computing (ATPESC), now in its third year. HPCwire: Can you give us an overview of the Argonne Training Program on Extreme-Scale Computing (ATPESC)? Paul Messina: Absolutely, Tiffany. The ATPESC Read more…

Practical Advice for Knights Landing Coders

Feb 5, 2015 |

The National Energy Research Scientific Computing Center (NERSC) is on track to get its next supercomputer system, Cori, by mid-2016. While that’s more than a year away, it’s not too soon to start preparing for the new 30+ petaflops Cray machine, which will feature Intel’s next-generation Knights Landing architecture. So says Richard Gerber, Senior Science Read more…
