Simulating HPC Workload Energy Costs

Feb 21, 2014 |

In today’s computing world, energy- and power-efficiency in data centers is critical to reducing a system’s overall total cost of ownership. Energy-efficiency is so important that the energy cost of operating a datacenter far exceeds its initial capital investment. In addition to cost savings, improvements in energy-efficiency also translate into lower carbon emissions. As Omar Read more…

How Can Supercomputers Survive a Drought?

Jan 26, 2014 |

Water scarcity has been surfacing as an extremely critical issue worth addressing in the U.S. as well as around the globe nowadays. A McKinsey-led report shows that, by 2030, the global water demand is expected to exceed the supply by 40%. According to another recent report by The Congressional Research Service (CRS), more than 70% Read more…

SC13 in Review: The Week’s Top Newsmakers

Nov 28, 2013 |

This year at SC13 we counted over 100 HPC-specific announcements that hit the wires over the course of the week, many of which were from vendors, organizations and users that we were within a short walk across the show floor in Denver. We wanted to point to some of the key newsmakers during the show, Read more…

HPC Power Efficiency and the Green500

Nov 20, 2013 |

The first Green500 List was launched in November 2007 ranking the energy efficiency of supercomputers. Co-founder Kirk W. Cameron discusses the events that led to creation of the Green500 List, its maturation, and future directions. An Early Supercomputer Efficiency “List” In 2001 the notions of Green HPC and energy proportional computing were unknown. There was Read more…

SC13 Research Highlight: Dynamic Electric Pricing for Energy Aware Scheduling

Nov 16, 2013 |

As supercomputers continue to grow, so do the associated electricity bills. These costs are now a leading component of total cost of ownership (TCO) of HPC systems. A team from the Illinois Institute of Technology and Argonne National Laboratory aims to reduce electricity expense of HPC systems via a smart batch scheduling mechanism. Their design Read more…

SC13 Research Highlight: COCA Targets Datacenter Costs, Carbon Neutrality

Nov 16, 2013 |

The rapid growth of high performance computing and cloud computing services in recent years has contributed to the dramatic increase in the number and scale of data centers, resulting in a huge demand for electricity. According to recent studies, the combined electricity consumption of global data centers amounts to 623 billion kWh annually and would Read more…

Cool and Steady Wins the Exascale Race

Nov 12, 2013 |

Power, energy and reliability present major challenges to HPC researchers in their endeavor to build larger machines. As we approach the exascale era, both hardware and software designers need to account for these challenges while optimizing performance. The Parallel Programming Laboratory (PPL) at the University of Illinois at Urbana-Champaign (UIUC) has been actively working on Read more…

Green500 Turns Blue

Jul 5, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Blue_Gene_Q_rack_blue.jpg” alt=”” width=”82″ height=”103″ />The latest Green500 rankings were announced last week, revealing that top performance and power efficiency can indeed go hand in hand. According to the latest list, the greenest machines, in fact the top 20 systems, were all IBM Blue Gene/Q supercomputers. Blue Gene/Q, of course, is the platform that captured the number one spot on the latest TOP500 list, and is represented by four of the ten fastest supercomputers in the world.

The TOP500 Celebrates 20th Anniversary, Will it Survive 20 More?

Jun 12, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/Hans_Meuer.jpg” alt=”” width=”85″ height=”85″ />With the upcoming release of the TOP500 next week, the latest rankings are usually a hot topic of discussion this time of year. Over the past 20 years, the list has proven to be a useful and popular compilation of supercomputers for the HPC community. In this exclusive interview, Professor Hans Meuer, considered by many to be the driving force behind the project, offers his thoughts on the TOP500; its past, present, and future.

Novel Chip Technology to Power GRAPE-8 Supercomputer

May 10, 2012 |

<img style=”float: left;” src=”http://media2.hpcwire.com/hpcwire/eASIC_logo_small.jpg” alt=”” width=”108″ height=”34″ />With the fastest supercomputers on the planet sporting multi-megawatt appetites, green HPC has become all the rage. The IBM Blue Gene/Q machine is currently number one in energy-efficient flops, but a new FPGA-like technology brought to market by semiconductor startup eASIC is providing an even greener computing solution. And one HPC project in Japan, known as GRAPE, is using the chips to power its newest supercomputer.
