Deep Dive: What Happens When a GPU Reads Memory?
somnial · hn · 2026-08-14
This is a comprehensive technical article exploring the underlying mechanisms of GPUs. From the perspective of hardware architecture and system scheduling, it dissects the data flow process within the chip and across the compute stack when a GPU initiates a memory read request.
The content covers core infrastructure topics like memory controllers, cache hierarchies, and bandwidth bottlenecks, offering valuable insights for understanding memory management and performance optimization during LLM training and inference.
