The Anatomy of an Instruction Pipeline Hazard
An analysis of instruction pipeline hazards on Nvidia B200 GPUs based on empirical microbenchmarks. The author explains how compiler-level scheduling errors can lead to silent correctness bugs in deep-pipeline hardware.
A note on methodology: Everything in this article is based on my analysis of microbenchmarks executed directly on B200 silicon. Nvidia does not publish instruction latencies, pipeline depths, or scoreboard encoding details for its GPUs. The numbers and mechanisms described here represent my best empirical understanding. Readers should do their own due diligence and verify against their own hardware.
