Report Addresses the Perils of Dark Silicon

Jul 21, 2016 |

Dark silicon refers to the processing potential that’s lost when thermal constraints disallow full CPU utilization. The gap between transistor scaling and voltage scaling combined with tighter integration of components (multicore, SoCs) has power density ramifications that are of particular concern for embedded computing, but high-performance computing faces similar “dark power” challenges. Bringing attention to this issue and exploring common solutions was the goal of the Dagstuhl Seminar 16052, “Dark Silicon: From Embedded to HPC Systems.”

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…

Alternative Supercomputing or How to Misuse a Computer

Jul 14, 2016 |

In 2008, the IBM Roadrunner supercomputer broke the petaflops barrier using the power of the heterogeneous Sony Cell Broadband Engine (BE) processor. A year prior, the Cell BE had already made its way into the consumer market as the engine inside the SonyPlaystation 3. The PS3’s accelerated design, Linux-capability and low price point…

LBNL Researchers Report Method to Make “Atomically Thin” Circuits

Jul 14, 2016 |

This week researchers from Lawrence Berkeley National Laboratory have reported a new method to create transistors and circuits that are only a few atoms thick. Their report, Large-scale chemical assembly of atomically thin transistors and circuits, published in Nature Nanotechnology, is another reminder that novel materials and approaches may indeed contribute to extending Moore’s law.

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).

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.

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.

Thomas Sterling’s ISC 2016 Closing Keynote

Jun 23, 2016 |

Capturing the sparkle, wit, and selective skewering in Thomas Sterling’s annual closing ISC keynote is challenging. This year was his 13th, which perhaps conveys the engaging manner and substantive content he delivers. Like many in the room, Sterling is an HPC pioneer as well as the director of CREST, the Center for Research in Extreme Scale Technologies, Indiana University. In his ISC talk, Sterling holds up a mirror to the HPC world, shares what he sees, and invites all to look in as well and see what they may.
