Application Readiness at the DOE, Part II: NERSC Preps for Cori

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…

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…

HSA Spec Lays Out Architecture for Acceleration

Mar 17, 2015 |

The Heterogeneous System Architecture (HSA) Foundation marked what it says will be known as a watershed event in heterogeneous computing with the release of the HSA 1.0 specification. The new spec, nearly three years in the making, brings the foundation closer to its goal of enabling write-once run-anywhere programming for accelerated computing on devices ranging from the Read more…

A Comparison of Heterogeneous and Manycore Programming Models

Mar 2, 2015 |

The high performance computing (HPC) community is heading toward the era of exascale machines, expected to exhibit an unprecedented level of complexity and size. The community agrees that the biggest challenges to future application performance lie with efficient node-level execution that can use all the resources in the node. These nodes might be comprised of Read more…

BSC, Intel Extend Exascale Research Effort

Feb 17, 2015 |

Intel’s efforts to advance exascale computing concepts received a boost with the extension of the company’s research collaboration with the Barcelona Supercomputing Center (BSC) – one of four Intel exascale labs in Europe. Begun in 2011 and now extended to September 2017, the Intel-BSC work focuses on scalability issues with parallel applications. “[A major goal] Read more…

Short Takes

Summit Puts 13 Code Projects Into Readiness Program

Apr 15, 2015 |

When the Oak Ridge National Laboratory’s Summit supercomputer powers up in 2018, it will provide the Department of Energy (DOE) research community with 150 to 300 peak petaflops of computational performance. To extract the highest benefit from this multi-million dollar machine that will be five to ten times the capability of the current fastest US 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…

DARPA Targets Autocomplete for Programmers

Nov 6, 2014 |

If Rice University computer scientists have their way, writing computer software could become as easy as searching the Internet. Two dozen computer scientists from Rice, the University of Texas-Austin, the University of Wisconsin-Madison and the company GrammaTech have joined forces to turn this promise into a reality. With $11 million in DARPA-funding, the group will Read more…
