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

Conquer Placement And Clock Tree Challenges In HPC Designs
By Janet Attar - 11 May, 2023 - Comments: 0

High-performance computing (HPC) applications require IC designs with maximum performance. However, as process technology advances, achieving high performance has become increasingly challenging. Designers need digital implementation tools and methodologies that can solve the thorny issues in HPC designs, including placement and clock tree challenges. Placement and clock tree synthesis are c... » read more

Placement And CTS Techniques For High-Performance Computing Designs
By Siemens EDA - 10 May, 2023 - Comments: 0

This paper discusses the challenges of designing high-performance computing (HPC) integrated circuits (ICs) to achieve maximum performance. The design process for HPC ICs has become more complex with each new process technology, requiring new architectures and transistors. We highlight how the Siemens Aprisa digital implementation solution can solve placement and clock tree challenges in HPC de... » read more

RISC-V Vectorization And Potential for HPC
By Technical Paper Link - 26 Apr, 2023 - Comments: 0

A new technical paper titled "Test-driving RISC-V Vector hardware for HPC" was published by researchers at University of Edinburgh. Abstract: "Whilst the RISC-V Vector extension (RVV) has been ratified, at the time of writing both hardware implementations and open source software support are still limited for vectorisation on RISC-V. This is important because vectorisation is crucial to obt... » 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

How To Raise Reliability, Availability, And Serviceability Levels For HPC SoCs
By Charlie Matar - 09 Feb, 2023 - Comments: 0

By Charlie Matar, Rita Horner, and Pawini Mahajan While once the domain of large data centers and supercomputers, high-performance computing (HPC) has become rather ubiquitous and, in some cases, essential in our everyday lives. Because of this, reliability, availability, and serviceability, or RAS, is a concept that more HPC SoC designers should familiarize themselves with. RAS may sound... » read more
