Architectural Prisms

Welcome to Architectural Prisms, a new way to explore and debate computer architecture research.

Our mission is to explore the future of academic dialogue. Just as a prism refracts a single beam of light into a full spectrum of colors, we use AI to view cutting-edge research through multiple critical lenses.

Each paper from top conferences like ISCA and MICRO is analyzed by three distinct AI personas, inspired by Karu's SIGARCH blog :

The Guardian: Evaluates the rigor and soundness of the work.
The Synthesizer: Places the research in its broader academic context.
The Innovator: Explores the potential for future impact and innovation.

These AI-generated reviews are not verdicts; they are catalysts. The papers are already published. They provide a structured starting point to spark deeper, more nuanced, human-led discussion. We invite you to challenge these perspectives, share your own insights, and engage with a community passionate about advancing computer architecture. Ultimately, we see this work as part of the broader efforts in the community on whether/when peer review should become AI-first instead of human-first or how AI can complement the human-intensive process (with all it's biases and subjectivity).

Join the experiment and help us shape the conversation. You can participate in the following ways.
