Keeping the Flow in Scientific Computing

Jul 28, 2014 |

Ilkay Altintas, deputy coordinator for research and director of SDSC’s Scientific Workflow Automation Technologies Laboratory, was recently named SDSC’s first ‘Pi Person of the Year.’ Named after the π symbol, the award recognizes researchers who as collaborators and innovators in applied research and development have one ‘leg’ in one or more science domains, and the Read more…

Big Data Needs Big Funding: NSF’s Jahanian Makes The Case

Jul 23, 2014 |

There’s no doubt that advanced computing and cyberinfrastructure are accelerating the pace of discovery and innovation in almost every field of inquiry. For Farnam Jahanian, this point was driven home in a recent meeting with senior members of the US Department of Agriculture. Yes, even farmers are getting in on the data/computation revolution. “At the Read more…

XSEDE14 Spotlights Recent Work, Future Plans

Jul 23, 2014 |

The XSEDE14 Conference, held in Atlanta from July 13-18, brought nearly 650 registrants (161 students), from over 200 organizations, 45 states (plus Puerto Rico and the Virgin Islands) and 10 countries. XSEDE14 chairperson Scott Lathrop and XSEDE Project Director John Towns opened the conference on Tuesday morning, offering updates on the conference and project as Read more…

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…

China’s Supercomputing Strategy Called Out

Jul 17, 2014 |

Since China’s Tianhe-2 supercomputer has successfully held on to its number one position for three iterations of the TOP500 list, there has been a lot of attention focused on just how useful this nearly 34-petaflops (LINPACK) beast actually is. In fact for many years the consensus on supercomputing in China has centered on a dearth of application Read more…

Compilers and More: MPI+X

Jul 16, 2014 |

At ISC’14, there was intense and continuing interest in the choice of a standard approach for programming the next generation HPC systems. While not guaranteed, many of these systems are likely to be large clusters of nodes with multicore CPUs and some sort of attached accelerators. A standard programming approach is necessary to convince developers, and Read more…

Solving Simulation Complexity

Jul 15, 2014 |

Although HPC has helped solve important problems in nuclear physics, earth sciences, meteorology, etc. since the 1960s, HPC has traditionally existed only for specialists. But, with the democratization of x86 servers, large storage systems, and high-end networking technologies, companies and research facilities can now buy clusters at a reasonable ratio (power/cost) with very powerful, complex Read more…

HPC2014: From Clouds and Big Data to Exascale and Beyond

Jul 14, 2014 |

The International Advanced Research Workshop has become leading reference after being celebrated for more than 20 years. You can blame Lucio Grandinetti (Full Professor at University of Calabria) and his team, who started all of this and managed to put together, year after year, the best in the computing think tank. This edition’s motto was Read more…
