Modern LLM architectures and systems render GPU kernel input shapes increasingly dynamic, e.g., conditional expert routing in MoE and batches with variable-length sequences. This dynamism degrades performance in both expert-tuned kernels and compiler frameworks. We identify the root cause as dynamic cross-SM data depen...

Operating systems must evolve continuously. Yet their development remains code-centric and largely manual: even a localized change can require recovering implicit assumptions, coordinating multiple subsystems, and repeatedly building, booting, testing, and debugging the complete system. General-purpose coding agents au...

File systems are critical OS components that require constant evolution to support new hardware and emerging application needs. However, the traditional paradigm of developing features, fixing bugs, and maintaining the system incurs significant overhead, especially as systems grow in complexity. This paper proposes a n...
