Comment: two Turing Award winners David Patterson and John Hennessey co-published 《A New Golden Age for Computer Architecture》

Copyright © 2021.10.14 Lin Pengcheng. All rights reserved.

In Communications of the ACM, February 2019, David Patterson and John Hennessey co-published a paper: 《A New Golden Age for Computer Architecture》, explaining their analysis and prospects for the development of computing architecture in the next ten years. The paper points out that a hardware-centric, domain-specific architectures (DSA) will provide significant performance and energy efficiency gains, bringing new vitality and development opportunities to computers as Moore's Law is coming to an end.

Comment

  • Just discover the advantages of DSA (Google TPU, etc.) currently on the market and predict that DSA will generate significant performance and energy efficiency benefits, But it did not specify what architecture should be used to organize, coordinate, and control these DSAs to complete tasks, Because the DSA application field is very limited, a new architecture must be designed to combine general-purpose CPUs and multiple DSAs to complete the task together. That is, a new computer architecture is not proposed to solve the problem.

  • If it is an article about DSA, it should cite Google TPU, ASIC related literature.

  • If it is to organize CPU and DSAs to complete tasks with a new computer architecture, then it should refer to my "The Grand Unified Programming Theory: The Pure Function Pipeline Data Flow with Principle-based Warehouse/Workshop Model".

Conclusion

The two Turing Award winners did not publish new views or solutions in this report. I don’t think there is any innovation in it. I don’t understand that so many people will cite this article. Is it just because of celebrity effects?

Anyone with ambition

  • Don't pointlessly cite low-quality and low-relevant celebrity articles, which will show that the author has no professional judgment.

  • Don't write citations just because the author of the reference is not well-known, it will show that the author's professional ethics is stained.
