Argonne’s Paul Messina on Training for Extreme-Scale

Mar 12, 2015 |

Paul Messina, director of science for the Argonne Leadership Computing Facility (ALCF), discusses the primary objectives, curriculum and importance of the Argonne Training Program on Extreme-Scale Computing (ATPESC), now in its third year. HPCwire: Can you give us an overview of the Argonne Training Program on Extreme-Scale Computing (ATPESC)? Paul Messina: Absolutely, Tiffany. The ATPESC 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…

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…

Preparing for Manycore

Oct 13, 2014 |

One of several insightful presentations to come out of the DOE Computational Science Graduate Fellowship was delivered by Katie Antypas, Services Department Head, National Energy Research Scientific Computing Center, Lawrence Berkeley National Laboratory. In “Preparing Your Application for Advanced Manycore Architectures,” Antypas gives a humorous and on-point overview of major architectural trends in HPC and Read more…

PayPal Finds Order from Chaos with HPC

Sep 24, 2014 |

At the 2014 HPC User Forum in Seattle, Ryan Quick and Arno Kolster from PayPal describe how the company is using HPC to transform its chaotic real-time server data into intelligent, actionable insight. The unique “Systems Intelligence” approach uses HP’s Moonshot server powered by TI processors to aggregate, analyze and act on transaction data in real time. Read more…

Programmability Matters

Jun 30, 2014 |

While discussions of HPC architectures have long centered on performance gains, that is not the only measure of success, according to Petteri Laakso of Vector Fabrics. Spurred by ever-proliferating core counts, programmability is taking on new prominence. Vector Fabrics is a Netherlands-based company that specializes in multicore software parallelization tools, so programmability is high on Read more…

Managing Memory at Multicore

Sep 18, 2013 |

With the advance of multicore and manycore processors, managing caches becomes more difficult. Researchers at MIT suggest that it might make sense to let software, rather than hardware, manage these high-speed on-chip memory banks.

The Week in HPC Research

May 2, 2013 |

We’ve scoured the journals and conference proceedings to bring you the top research stories of the week. This diverse set of items includes the latest CAREER award recipient; the push to bring parallel computing to the classroom; HPC in accelerator science; the emerging Many-Task Computing paradigm; and a unified programming model for data-intensive computing.

The Week in HPC Research

Apr 11, 2013 |

The top research stories of the week include an evaluation of multi-stage programming with Terra; a look at parallel I/O for multicore architectures; a survey of on-chip monitoring approaches used in multicore SoCs; a review of grid security protocols and architectures; and a discussion of the finer distinctions between HPC and cloud computing.
