Weekly recaps and reflections from Harvard’s CS249r: Architecture 2.0
Over the past four weeks, we’ve been exploring a central question: can AI systems help us optimize performance at scale? We started with the foundational challenges of Architecture 2.0, examined the software engineering reality gap between AI capabilities and real development tasks, and investigated how Google’s ECO system tackles CPU...

OpenAI’s GPT-5 managed to achieve a perfect score, answering 12 out of 12 problems, a performance akin to winning a gold medal. Not to be outdone, Google’s Gemini 2.5 Deep Think solved 10 of...
Read More →As we were teaching class this very Wednesday, September 17th, news broke that Google DeepMind’s Gemini achieved gold medal level performance at the 2025 International Collegiate Programming Contest (ICPC) World Finals, solving 10 of 12 complex algorithmic problems in the world’s most prestigious competitive programming competition.Gemini’s ICPC performance builds on...
Read More →Here’s what nobody tells you about applying AI to computer architecture: it’s not just harder than other domains—it’s fundamentally different in ways that make most AI success stories irrelevant. This week, we confronted why the techniques that conquered vision, language, and games stumble when faced with cache hierarchies and instruction...
Read More →Moore’s Law is dying. Dennard scaling ended years ago.Dennard scaling, formulated by Robert Dennard at IBM in 1974, observed that as transistors became smaller, their switching voltage and current could be reduced proportionally, keeping power density roughly constant. This meant each new generation delivered faster processors without exponentially increasing power...
