New Degrees of Parallelism, Old Programming Planes

Aug 28, 2014 |

Exploiting the capabilities of HPC hardware is now more a matter of pushing into deeper levels of parallelism versus adding more cores or overclocking. What this means is that the time is right for a revolution in programming. The question is whether that revolution should be one that torches the landscape or that handles things Read more…

NERSC Launches Exascale Readiness Program with Intel, Cray

Aug 11, 2014 |

The National Energy Research Scientific Computing Center (NERSC) is collaborating with supercomputing vendors Intel and Cray to prepare for Cori, the Cray XC supercomputer scheduled to be deployed at NERSC in 2016. Named in honor of American biochemist Gerty Cori, the next-generation supercomputer will have a sustained performance that is at least ten times that Read more…

Exascale Resilience Turns a Corner

Jul 21, 2014 |

While advancing the field of HPC into the exascale era is beset by many obstacles, resiliency might be the most thorny of all. As the number of cores proliferate so too do the number of incorrect behaviors, threatening not just the operation of the machine, but the validity of the results as well. When you Read more…

Intel Gives Code Modernization Fresh Push

May 28, 2014 |

In the conversations leading up to exascale, one of the most frequently cited pain points is the need for massive software optimization and code modernization. But this isn’t just a relevant topic for the largest system operators at the supercomputing pinnacle. According to Intel’s General Manager of the Technical Computing Group, Charlie Wuischpard, there are Read more…

Altair Crash Tests New Xeon E7s

Mar 12, 2014 |

RADIOSS, one of the top structural analysis solvers in the industry, is used by auto companies like Ford and PSA in France to run car crash and other simulations to test safety and viability of a broad array of products. Like similar CAE codes, it is highly parallelized for top performance on large, powerful clusters–and Read more…

Short Takes

An Easier, Faster Programming Language?

Jun 18, 2014 |

The HPC community has turned out supercomputers surpassing tens of petaflops of computing power by stringing together thousands of multicore processors, often in tandem with accelerators like NVIDIA GPUs and Intel Phi coprocessors. Of course, these multi-million dollar systems are only as useful as the programs that run on them, and developing applications that can Read more…

Internship Program Fosters HPC Talent

May 21, 2014 |

One of the most pressing concerns in HPC circles continues to be a lack of qualified entrants to the field. Not to say there isn’t talent — the popularity and success of the student cluster challenges attest to that — but it’s not enough to span the gap. That’s why efforts to facilitate this unique skill Read more…

Evolving Exascale Applications Via Graphs

Apr 29, 2014 |

There is little point to building expensive exaflop-class computing machines if applications are not available to exploit the tremendous scale and parallelism. Consider that exaflop-class supercomputers will exhibit billion-way parallelism, and that calculations will be restricted by energy consumption, heat generation, and data movement. This level of complexity is sufficient to stymy application development, which Read more…

Prioritizing Data in the Age of Exascale

Apr 14, 2014 |

By now, most HPCers and the surrounding community are aware that data movement poses one of the most fundamental challenges to post-petascale computing. Around the world exascale-directed projects are attempting to maximize system speeds while minimizing energy costs. In the US, for example, exascale targets have peak performance increasing by three orders of magnitude while Read more…

Simulating HPC Workload Energy Costs

Feb 21, 2014 |

In today’s computing world, energy- and power-efficiency in data centers is critical to reducing a system’s overall total cost of ownership. Energy-efficiency is so important that the energy cost of operating a datacenter far exceeds its initial capital investment. In addition to cost savings, improvements in energy-efficiency also translate into lower carbon emissions. As Omar Read more…
