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…

Revisiting Supercomputer Architectures

Dec 8, 2011 |

Additional performance increases for supercomputers are being confounded by three walls: the power wall, the memory wall and the datacenter wall (the “wall wall”). To overcome these hurdles, the market is currently looking to a combination of four strategies: parallel applications development, adding accelerators to standard commodity compute nodes, developing new purpose-built systems, and waiting for a technology breakthrough.
