Top500: Frontier Still On Top, Sunway Formally Reappears
By Barry Pangrle - 05 Jan, 2024 - Comments: 0

New versions of the Top500 and Green500 lists have been released, and Frontier continues its reign at Number. 1. But a newcomer, Aurora, using Intel’s Sapphire Rapids, has entered at the Number 2 position with a “half-scale” system. Both machines are HPE Crays, with the former using AMD optimized third-gen EPYC 64C at 2.0GHz and AMD Instinct MI250X, while the latter uses Intel Xeon CPU... » read more

Supercomputing Efficiency Lags Performance Gains
By Barry Pangrle - 30 Jun, 2023 - Comments: 0

In last month’s article, Top 500: Frontier is Still on Top, I wrote about the latest versions of the Top500 and Green500 lists. Power is an incredibly important aspect of designing a world performance leading supercomputer. (Why, I can remember back to when you could run the world’s fastest machine on only a couple MW of power.) The first Green500 list was published back in 2013. Happy 1... » 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

A New Era For HPC-Driven Engineering Simulation
By Ansys - 12 Sep, 2022 - Comments: 0

Market pressure and technological advancements have rapidly changed the way engineers work. Design engineers increasingly work with larger and more complex models, must conduct more frequent simulation analysis, and iterate more rapidly. Compute constraints, however, often result in engineers limiting model sizes and simulation fidelity, or relying on lengthy, overnight simulation runs. ... » read more

Considerations for Neuromorphic Supercomputing in Semiconducting and Superconducting Optoelectronic Hardware
By Technical Paper Link - 18 Nov, 2021 - Comments: 0

Abstract: "Any large-scale spiking neuromorphic system striving for complexity at the level of the human brain and beyond will need to be co-optimized for communication and computation. Such reasoning leads to the proposal for optoelectronic neuromorphic platforms that leverage the complementary properties of optics and electronics. Starting from the conjecture that future large-scale neurom... » read more

Supercomputers Are For Everyone
By Mike Gianfagna - 29 Nov, 2018 - Comments: 0

Our SerDes world tour continues. This past month, we demonstrated our 7nm 56G long-reach SerDes in Dallas and Israel. In Dallas, our demonstration included error-free operation in 56G PAM4 over a 30dB channel without forward error correction through an eye-popping five-meter cable. Many thanks to our partner Samtec for providing that cable, allowing backplane designers to now “reach beyond th... » read more
