The Journey To Exascale Computing And Beyond
By Steven Woo - 14 Dec, 2023 - Comments: 0

High performance computing witnessed one of its most ambitious leaps forward with the development of the US supercomputer “Frontier.” As Scott Atchley from Oak Ridge National Laboratory discussed at Supercomputing 23 (SC23) in Denver last month, the Frontier had the ambitious goal of achieving performance levels 1000 times higher than the petascale systems that preceded it, while also stayi... » read more

SG2042 64-Core RISC-V CPU Versus Existing RISC-V HW And High Performance x86 CPUs
By Technical Paper Link - 13 Sep, 2023 - Comments: 0

A technical paper titled “Is RISC-V ready for HPC prime-time: Evaluating the 64-core Sophon SG2042 RISC-V CPU” was published by researchers at University of Edinburgh. Abstract: "The Sophon SG2042 is the world's first commodity 64-core RISC-V CPU for high performance workloads and an important question is whether the SG2042 has the potential to encourage the HPC community to embrace RISC-... » read more

Top500: Frontier Is Still On Top
By Barry Pangrle - 25 May, 2023 - Comments: 0

The latest versions of the Top500 and Green500 lists were just released on May 22, 2023. The last time that I wrote about the Green500, a Chinese machine, NRCPC’s Sunway TaihuLight, was sitting at the top of the Top500 list. It’s been a while since I last wrote about these lists and it’s interesting to look back at the leap in performance and energy efficiency over the past 7 years. ... » read more

Is RISC-V Ready For Supercomputing?
By Brian Bailey - 09 Feb, 2023 - Comments: 0

RISC-V processors, which until several years ago were considered auxiliary processors for specific functions, appear to be garnering support for an entirely different type of role — high-performance computing. This is still at the discussion stage. Questions remain about the software ecosystem, or whether the chips, boards, and systems are reliable enough. And there are both business and t... » read more

Chiplets Enter The Supercomputer Race
By Mark LaPedus - 17 Mar, 2022 - Comments: 0

Several entities from various nations are racing each other to deliver and deploy chiplet-based exascale supercomputers, a new class of systems that are 1,000x faster than today’s supercomputers. The latest exascale supercomputer CPU and GPU designs mix and match complex dies in advanced packages, adding a new level of flexibility and customization for supercomputers. For years, various na... » read more

Building Fugaku, The World’s Fastest Supercomputer
By Satoshi Matsuoka - 09 Jul, 2020 - Comments: 1

My fascination with computers started back in 1976. I remember it well: I was in the 8th grade, and I’d just returned to Japan from a stint in the US. One day I found myself in Tokyo’s Akihabara area, otherwise known as ‘Electric Town.’ This place was and still is the tech heartbeat of Japan, bright and buzzing with all the latest gadgets. On this particular day, among the displays of ... » read more

No More Pizza! The Power Of HPC To Answer: “What’s For Dinner?”
By Ruben Molina - 26 Sep, 2019 - Comments: 0

The other night my wife and I were trying to pick a place we could both agree on for dinner. If you’ve ever been in this situation, you know it can be a difficult problem to solve. I decided to short circuit the usual torture by asking our virtual assistant for a solution. “Hey [Virtual Assistant], where’s a good place to eat?” Thus ensued 15 minutes of intermittent, wrong answers, misc... » read more

System Bits: July 10
By Jeff Dorsch - 10 Jul, 2019 - Comments: 0

Light waves run on silicon-based chips Researchers at the University of Sydney’s Nano Institute and Singapore University of Technology and Design collaborated on manipulating light waves on silicon-based microchips to keep coherent data as it travels thousands of miles on fiber-optic cables. Such waves—whether a tsunami or a photonic packet of information—are known as solitons. The... » read more

System Bits: June 25
By Jeff Dorsch - 25 Jun, 2019 - Comments: 0

Supercomputers around the world At last week’s International Supercomputing Conference in Frankfurt, Germany, the 53rd biannual list of the Top500 of the most powerful computing systems in the world was released. Broken out by countries of installation, China has 219 of the world’s 500 fastest supercomputers, compared with 116 in the United States. Ranking by percent of list flops, the ... » read more
