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

Breaking Down The AI Memory Wall
By Steven Woo - 12 Sep, 2019 - Comments: 0

Over the past few decades, the semiconductor industry has witnessed the rapid evolution of memory technology as new memories helped to usher in new usage models that characterized each decade. For example, synchronous memory helped drive the personal computer (PC) revolution in the 1990s, and this was quickly followed by specialized graphics memory (GPUs) for game consoles in the 2000s. When sm... » read more

How AI Impacts Memory Systems
By Steven Woo - 08 Mar, 2018 - Comments: 0

Throughout the 1980’s and early 1990’s computer systems were bottlenecked by relatively slow CPU performance, thereby limiting what applications could do. Driven by Moore’s Law, transistor counts increased significantly over the years, improving system performance and enabling exciting new computing possibilities. Although computing capabilities have advanced significantly in recen... » read more

The Data Center In 2018 And Beyond
By Steven Woo - 11 Jan, 2018 - Comments: 0

As computing continues to evolve, a number of trends are continuing to challenge the design of conventional von Neumann architectures, and in turn are driving the development of new architectural approaches and technologies. These include the growing adoption of artificial intelligence (AI), machine learning, AR/VR, IoT, high-speed financial transactions, self-driving vehicles, and blockchain/c... » read more

What Comes After Moore’s Law And Dennard Scaling?
By Steven Woo - 08 Dec, 2016 - Comments: 0

For decades, Moore’s Law has been an important semiconductor industry mainstay that has helped fuel a relentless progression in computing performance. However, most industry experts agree that Moore’s Law is waning, with an end on the horizon due to a combination of physical limitations and economic factors. With the loss of Dennard Scaling roughly 10 years ago, the industry is at a critica... » read more

Faster SerDes For More Efficient Data Centers
By Steven Woo - 10 Nov, 2016 - Comments: 0

The evolving data center presents an imposing set of challenges for system architects as Dennard Scaling fades and Moore’s Law wanes. These include an exponential increase in data, shifting architectural bottlenecks and a never-ending demand for higher performance within the same power and thermal envelopes. The Internet of Things (IoT), Big Data analytics, in-memory computing and machine ... » read more

From The Data Center To The Mobile Edge
By Steven Woo - 13 Oct, 2016 - Comments: 0

At the heart of the Internet of Things is the complex interplay between the needs for both low power and high performance (LPHP), a perplexing challenge rooted in the de-facto bifurcation of the IoT itself. For example, lower power mobile devices, systems and lite endpoints make up the vast majority of forward-facing consumer infrastructure, while high-performance servers at the back end are ta... » read more

Shifting Performance Bottlenecks Driving Change In Chip And System Architectures
By Steven Woo - 14 Jan, 2016 - Comments: 0

The rise of personal computing in the 1980s — along with graphical user interfaces (GUIs) and applications ranging from office apps to databases — drove the demand for faster chips capable of removing processing bottlenecks and delivering a more responsive end-user experience. Indeed, the semiconductor industry has certainly come quite a long way since IBM launched its PC way back in 1981. ... » read more

Addressing Modern Bottlenecks With Smart Data Acceleration
By Steven Woo - 10 Dec, 2015 - Comments: 0

Over the past 30 years, the relentless progression of Moore’s Law has driven dramatic improvements in transistor counts and ultimately in processor performance. CPU performance was often the primary factor in determining overall system performance, leading us to believe that better CPUs led to better system performance. But, as processors have become more powerful, other subsystems have not k... » read more

Exploring System Architectures For Data-Intensive Applications
By Steven Woo - 08 Oct, 2015 - Comments: 0

The exponential growth of digital data is being driven by a number of factors, including the burgeoning Internet of Things (IoT) and an increased reliance on complex analytics extracted from extremely large data sets. Perhaps not surprisingly, IDC analysts see digital data doubling roughly every two years. This dramatic growth continues to challenge, and in some cases, even outpace industry cap... » read more
