Wafer Scale and Trilogy Systems: Part 1

Cerebras Systems is making headlines with its Wafer Scale Integration (WSI) technology, which allows for the creation of large integrated circuits from entire silicon wafers. This innovation is part of Cerebras's strategy to accelerate AI training and inference, positioning itself against established competitors like Nvidia and AMD. The concept of WSI is not new; it dates back to the 1980s when pioneers like Jack Kilby recognized its potential to simplify designs and enhance performance by reducing the number of interconnects between chips. However, challenges such as defect management and heat dissipation have historically hindered its commercial viability. Gene Amdahl, a key figure in computer architecture, co-founded Trilogy Systems in 1979 to explore WSI further. Trilogy aimed to develop IBM-compatible mainframes using WSI technology, which promised significant performance improvements. Despite facing intense competition and financial scrutiny, Amdahl's vision for WSI was ambitious, suggesting that it could outperform existing systems by a considerable margin. The article highlights the historical context of WSI, tracing its evolution from theoretical concepts to practical applications in modern computing, particularly in AI.
