XSEDE Allocation System to Receive Makeover

Jul 22, 2014 |

XSEDE is a set of resources and systems that thousands of researchers, scientists and engineers regularly use to do groundbreaking science. But how does an XSEDE user actually request time on supercomputers or ask for time with XSEDE-supported resource experts? As of now, XSEDE users turn to POPS (Partnerships Online Proposal System), a system that Read more…

Of Micelles and Machines: HPC Simulations Transform Everyday Household Products

Jul 22, 2014 |

Have you ever dropped your brand new razor or a full bottle of hand soap on a tiled bathroom floor and wondered why it didn’t simply shatter into a dozen pieces or split apart and create a gooey mess? Maybe next time that happens, you’ll thank computer modeling and simulations, not just your lucky stars. 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…

Supercomputing Makes for Smarter Chinese Cities

Aug 19, 2014 |

Home to some of the world’s fastest supercomputers, China is looking to apply that computing power to solve issues that are important to its populace. On Monday, a Chinese researcher revealed a plan to use China’s Tianhe-1A system toward the construction of new “smart cities.” Taking an interdisciplinary approach to the challenges of urban planning, Read more…

Deconstructing Moore’s Law’s Limits

Aug 18, 2014 |

For the past five decades, computers have progressed on a predictable trajectory, doubling in speed roughly every two years in tune with Gordon Moore’s oft-cited observation-turned-prophecy. Although semiconductor scaling continues to yield performance gains, many perceive a tipping point is nigh, where the cost-benefit analysis of further miniaturization breaks down. The latest researcher to weigh Read more…
