Jetstream: Targeting the Long Tail of Science

May 21, 2015 |

Improving HPC access to the so-called long tail of science is an ongoing NSF priority. Several initiatives, funded at least in part by NSF, are underway and one – Jetstream – is the first NSF-funded HPC Cloud targeted directly at domain scientists and engineers who typically have limited access to HPC resources and limited expertise.

Apr 17, 2015 |

In our second video feature from the HPC User Forum panel, “The Who-What-When of Getting Applications Ready to Run On, And Across, Office of Science Next-Gen Leadership Computing Systems,” we learn more about the goals and challenges associated with getting science applications ready for the coming crop of Department of Energy (DOE) supercomputers, which in addition to being five-to-seven times faster than Read more…

Application Readiness at the DOE, Part I: Oak Ridge Advances Toward Summit

Apr 16, 2015 |

At the 56th HPC User Forum, hosted by IDC in Norfolk, Va., this week, three panelists from major government labs discussed how they are getting science applications ready for the coming crop of Department of Energy (DOE) supercomputers, which in addition to being five-to-seven times faster than today’s fastest big iron machines, constitute significant architectural changes. Titled “The Who-What-When of Getting Applications Ready to 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…

ROSE Framework Blooms Toward Exascale

Feb 12, 2015 |

One of the many ways that the Office of Advanced Scientific Computing Research (ASCR) supports the Department of Energy Office of Science facilities is by championing the research that powers computational science. A recent ASCR Discovery feature takes a look at how the DOE science community is preparing for extreme-scale programming. As supercomputers reach exascale Read more…

Scalable Priority Queue Minimizes Contention

Feb 2, 2015 |

The multicore era has been in full-swing for a decade now, yet exploiting all that parallel goodness remains a prominent challenge. Ideally, compute efficiency would scale linearly with increased cores, but that’s not always the case. As core counts are only set to proliferate across the computing spectrum, it’s an issue that merits serious attention. Researchers from Read more…
