Synthesized Summary

While the Supermesh paper's overall SIMD mesh architecture and centralized, low-level control are largely obsolete compared to modern accelerators, its unique proposed decentralized coupled-oscillator clock mechanism (Section 2.3) presents a specific, unconventional timing approach.

However, the practical robustness and scalability of this clocking method against modern manufacturing variations remain unproven.

Furthermore, the idea of designing computation to inherently "surf" these physical timing wavefronts is highly speculative, lacking concrete models or demonstrated advantages over mature synchronous, asynchronous, or GALS paradigms for general computational tasks.

Optimist's View

The most intriguing and potentially impactful aspect of the SUPERMESH paper for modern research lies not just in its SIMD mesh architecture or serial processing ideas..., but specifically in its proposed decentralized, wavefront-propagating clocking mechanism based on coupled oscillators using C-elements (Section 2.3).

This specific timing paradigm... could fuel unconventional research in the design of future massive-scale integrated systems, particularly in neuromorphic computing and highly specialized AI accelerators.

A SUPERMESH-inspired coupled oscillator approach could offer a more naturally scalable, potentially lower-power method for local synchronization and communication timing across large physical areas, where the computation and communication naturally synchronize with the physical clock wavefronts.

This could lead to novel spatial computing models or dataflow architectures where operations are triggered not by a global pulse, but by the arrival of a local timing wavefront, potentially simplifying control logic per node and maximizing energy efficiency for tasks that map well to this spatiotemporal execution model...

Skeptic's View

The core concept of a large-scale, fine-grain SIMD mesh architecture, controlled solely by a central computer issuing low-level operations (register moves, port shifts, AU ops), has seen its relevance dramatically decay for general-purpose parallelism.

Programming a machine where you manually schedule bit-serial shifts, word-pair arithmetic steps, and pipelined commands across a spatially skewed array is an exercise in masochism.

Relying on the precise wave propagation of the custom clock and pipelined commands for synchronization across potentially millions of nodes seems inherently brittle.

Modern GPUs and other accelerators have completely surpassed the potential of the Supermesh design for the types of problems it aimed to solve.
