For decades, we have designed chips in fundamentally the same way: human intuition applied to a vanishingly small slice of an impossibly large design space. That paradigm worked when Moore’s Law was lifting everything. We could afford to be wrong. We could...

Years ago, I came across three pioneering works (CSI-NN, Cache Telepathy, and DeepSniffer) in the field of reverse engineering neural networks that inspired my journey into side-channel attacks to uncover the secrets of modern Deep Neural Networks (DNNs). Fast forward...

The debate of sparsity versus quantization has made its rounds in the ML optimization community for many years. Now, with the Generative AI revolution, the debate is intensifying. While these might both seem like simple mathematical approximations to an AI researcher,...

Large language model (LLM) agents are quickly moving from “single agent” to *multi-agent systems*: tool-using agents, planner-orchestrator, debate teams, specialized sub-agents that collaborate to solve tasks. At the same time, the *context* these agents must operate...

TL;DR: Latency-tolerant architectures, e.g., GPUs, increasingly use memory/storage hierarchies, e.g., for KV Caches to speed Large-Language Model AI inference. To aid codesign of such workloads and architectures, we develop the simple PipeOrgan analytic model for...
