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…

Run Anywhere Big Data and HPC Workloads

Feb 9, 2015 |

A classical problem in software development is how you manage your software applications dependencies. This extends all the way from the time you program your application to the time you run or deploy it. The typical application is almost always dependent on specific versions of libraries, compilers or the OS level package management system. Organizations Read more…

Practical Advice for Knights Landing Coders

Feb 5, 2015 |

The National Energy Research Scientific Computing Center (NERSC) is on track to get its next supercomputer system, Cori, by mid-2016. While that’s more than a year away, it’s not too soon to start preparing for the new 30+ petaflops Cray machine, which will feature Intel’s next-generation Knights Landing architecture. So says Richard Gerber, Senior Science Read more…

Is U.S. Falling Behind in Supercomputing and Exascale?

Jan 29, 2015 |

Few dispute the importance of supercomputing to U.S. competitiveness. The argument is around whether current government efforts – primarily through the Advanced Scientific Computing Research (ASCR) program within the U.S. Department of Energy (DOE) – are effective and sufficient or wasteful and excessive. Yesterday, a panel of HPC experts testifying at a U.S. House of Read more…

Short Takes

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…
