Artificial Intelligence Wonderland
By Barry Pangrle - 30 Nov, 2023 - Comments: 0

Silicon Catalyst held its Sixth Annual Semiconductor Forum in Menlo Park on the SRI campus on November 9th. Richard Curtin, Managing Partner for Si Catalyst, opened the event with a reference to Arthur C. Clarke’s "2001: A Space Odyssey" and noted how remarkable it was that a novel written back in 1968 was able to foretell the direction of the computer industry over 50 years into the future. ... » read more

Leaps in Quantum Computing
By Barry Pangrle - 26 Oct, 2023 - Comments: 0

There are new computers that are generating some amazing results for solving problems in record time.  You won’t see these computers on the classic Top500 lists though, because they aren’t approaching computing in the same way. Using quantum computing algorithms like Shor’s algorithm for factoring large numbers, quantum computing holds the promise of solving problems that take exponentia... » read more

IBM’s Energy-Efficient NorthPole AI Unit
By Barry Pangrle - 28 Sep, 2023 - Comments: 0

At this point it is well known that from an energy efficiency standpoint, the biggest bang for the back is to be found at the highest levels of abstraction. Fitting the right architecture to the task at hand i.e., an application specific architecture, will lead to benefits that are hard or impossible to claw back later in the design and implementation flow.  With the huge increase in the inter... » read more

Performance & Efficiency Cores For Servers

HotChips 2023 was held August 27-29, 2023 at Stanford University in California and was the first in-person version of the conference in 4 years. The conference was held in a hybrid format that had over 500 participants in-person and over 1,000 attending virtually online. Topics covered a broad range of advancements in computing, connectivity, and computer architecture. Both AMD and Intel gav... » read more

Balancing IR Drop Unpredictability With Post-Silicon Flexibility
By Aakash Jani - 24 Aug, 2023 - Comments: 0

The concept of IR drop in silicon chips has always been a crucial aspect of chip design. However, recent technological trends and the emergence of new challenges, such as voltage-sensitive paths, have introduced a degree of uncertainty in predicting and effectively managing IR drop. These uncertainties are driving the need for a more flexible approach in mitigating on-die voltage droop. Increa... » read more

Managing Voltage Variation
By Barry Pangrle - 07 Aug, 2023 - Comments: 0

Engineers make many tradeoffs when designing SoC’s to better meet design specifications. Power, Performance and Area (PPA) are the primary goals and all three impact the cost of the implementation. For example, higher power and performance can both require more expensive packaging for power and signal integrity as well as cooling. The larger the die area the fewer die per wafer which drives u... » 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

Mitigating Voltage Droop
By Aakash Jani - 13 Jun, 2023 - Comments: 0

Voltage droop, also known as IR drop, is a phenomenon that occurs when the current in the power delivery network abruptly changes due to workload fluctuations. This can lead to supply voltage drops across system-on-chips (SoCs) which can cause severe performance degradation, limit their energy efficiency, and in extreme cases can cause catastrophic timing failures. To avoid these issues, conven... » 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

TSMC Targets N2 Production For 2025
By Barry Pangrle - 02 May, 2023 - Comments: 0

April ended with TSMC’s financial results for the 1st Quarter of 2023 reported on April 20, 2023, and their North American Technology Symposium was held on April 27 at the Santa Clara Convention Center. TSMC’s N3 entered volume production in 4Q 2022 and TSMC’s N2 “nanosheet” technology is on schedule for production in 2025. TSMC’s CEO, C.C. Wei, said during the 1Q conference cal... » read more
