MIT’s Multicore Swarm Architecture Advances Ordered Parallelism

Jul 21, 2016 |

A relatively new architecture explicitly designed for parallelism – Swarm – based on work at MIT has shown promise for substantially speeding up classes of applications (graphs, for example) and decreasing the programming burden to achieve parallelism. The work, recounted in a recent paper, Unlocking Ordered Parallelism with the Swarm Architecture, bucks conventional wisdom and Read more…

RISC-V Startup Aims to Democratize Custom Silicon

Jul 13, 2016 |

Momentum for open source hardware made a significant advance this week with the launch of startup SiFive and its open source chip platforms based on the RISC-V instruction set architecture. The founders of the fabless semiconductor company — Krste Asanovic, Andrew Waterman, and Yunsup Lee — invented the free and open RISC-V ISA at the University of California, Berkeley, six years ago. The progression of RISC-V and the launch of SiFive opens the door to a new way of chip building that skirts prohibitive licensing costs and lowers the barrier to entry…

ISC Workshop Tackles the Co-development Challenge

Jul 12, 2016 |

The long percolating discussion over ‘co-development’ and how best it should be undertaken has gained new urgency in the race towards exascale computing. At a workshop held at ISC2016 last month – Form Follows Function: Do algorithms and applications challenge or drag behind the hardware evolution? – several distinguished panelists offered varying viewpoints. Yesterday, session organizer Tobias Weinzierl posted a summary synopsis of the workshop discussion on arXiv.org. Weinzierl (Durham University) and co-organizer Michael Bader (Technische Universität München) are active participants in the ExaHyPE project (An Exascale Hyperbolic PDE (partial differential equation) Engine, funded by EU’s Horizon 2020 program).

OLCF Researchers Scale R to Tackle Big Science Data Sets

Jul 6, 2016 |

Sometimes lost in the discussion around big data is the fact that big science has long generated huge data sets. “In fact, large-scale simulations that run on leadership-class supercomputers work at such high speeds and resolution that they generate unprecedented amounts of data. The size of these datasets—ranging from a few gigabytes to hundreds of Read more…

Trinity Wrestles with Knights Landing Programming Challenge with COE

Jul 5, 2016 |

Seventy-one years ago, on July 16, 1945, an incredible explosion lit up the New Mexico night sky. This was the Trinity Test, the world’s first nuclear detonation, and it marked the beginning of the Nuclear Age. It also ushered in the age of supercomputers, which essentially began with weapons science at Los Alamos National Laboratory (LANL). Now a new Trinity, a next generation Cray XC supercomputer is about to take center stage to help the national security labs achieve their primary mission – to provide the nation with a safe, secure and effective nuclear deterrent.

This year’s JuliaCon was the biggest yet, and featured presentations describing how Julia is being used Read more…

Compilers and More: OpenACC to OpenMP (and back again)

Jun 29, 2016 |

In the last year or so, I’ve had several academic researchers ask me whether I thought it was a good idea for them to develop a tool to automatically convert OpenACC programs to OpenMP 4 and vice versa. In each case, the motivation was that some systems had OpenMP 4 compilers (x86 plus Intel Xeon Phi Knights Corner) and others had OpenACC (x86 plus NVIDIA GPU or AMD GPU), and someone wanting to run a program across both would need two slightly different programs. In each case, the proposed research sounded like a more-or-less mechanical translation process, something more like a sophisticated awk script, and that’s doomed from the start. I will explain below in more detail how I came to this conclusion.

Heading into ISC16, OpenHPC Releases Latest Stack with 60-plus Packages

Jun 16, 2016 |

SC15 was sort of a muted launch party for OpenHPC – the nascent effort to develop a ‘plug-and-play’ software framework for HPC. There seemed to be widespread agreement the idea had merit, not a lot of knowledge of details, and some wariness because Intel was a founding member and vocal advocate. Next week, ISC16 will mark the next milestone for OpenHPC, which has since grown into a full-fledged Linux Foundation Collaborative Project and today released version 1.0.1 of OpenHPC (build and test tools).

Exiting Intel, James Reinders Offers a Brief Personal Retrospective

Jun 6, 2016 |

You may have heard that Intel has encouraged “long timers” (like me) to consider early retirement. Well, the offer was convincing for me. After 10,001 days at Intel, it is time for me to start the next phase of my life. I’ve accepted the “ERP offer” (early retirement) with my last day being June 24, 2016 (exactly 10,000 days after my start date). I’ll be in the office as much as needed to help transitions and wrap things up. Let me know if you need/want anything from me as I finish up.

GPU-based Deep Learning Enhances Drug Discovery Says Startup

May 26, 2016 |

Sifting the avalanche of life sciences (LS) data for insight is an interesting and important challenge. Many approaches are used with varying success. Recently, improved hardware – primarily GPU-based – and better neural networking schemes are bringing deep learning to the fore. Two recent papers report the use of deep neural networks is superior to typical machine learning (support vector machine model) in sieving LS data for drug discovery and personalized medicine purposes.

ORNL Researchers Create Framework for Easier, Effective FPGA Programming

May 24, 2016 |

Programmability and portability problems have long inhibited broader use of FPGA technology. FPGAs are already widely and effectively used in many dedicated applications (accelerated packet processing, for example), but generally not in situations that require ‘reconfiguring’ the FPGA to accommodate different applications. A group of researchers from Oak Ridge National Laboratory is hoping to change that.
