NERSC Highlights Exascale-Energy Connection

Sep 11, 2014 |

It’s been almost six months since the National Energy Research Scientific Computing Center (NERSC) formally announced Cori, the new supercomputer set to be installed at the lab in the mid-2016 timeframe. Originally known as NERSC-8, the new machine will sport over 9,300 nodes, equipped with next-generation Knights Landing architecture housed within a Cray XC environment. Each Read more…

Tackling the Power and Energy Wall for Future HPC Systems

Dec 17, 2013 |

As the cost of powering a supercomputer or a datacenter increases, next generation exascale systems need to be considerably more power- and energy-efficient than current supercomputers to be of practical use. Unlike petascale systems, where the primary concern was performance, exascale systems need to climb the power and energy walls in order to deliver sustainable exaflops performance. Pacifi c Northwest Laboratory (PNNL) researchers are exploring holistically energy and power efficiency aspects at all levels of granularity, from processor architecture to system integration.

Exascale Requires 25x Boost in Energy Efficiency, NVIDIA’s Dally Says

Jun 24, 2013 |

While there is a universal desire in the HPC community build the world’s exascale system, the achievement will require a major breakthrough in not only chip design and power utilization but programming methods, NVIDIA chief scientist Bill Dally said in a keynote address at ISC 2013 last week in Leipzig, Germany.
