hbm

Separate storage scope from physical backing, then follow a warp through adjacent and strided loads. Count useful bytes and requested sectors before inferring HBM traffic or speed.

Derive HBM bandwidth from interface width and pin rate, then connect it to a model that actually fits. Separate raw interface capacity from measured decode time.

A proposal for more memory bandwidth needs a workload that benefits, a budget for what it costs, and a reason to abandon it. Work through a serving-specific design without assuming all LLM work has the same bottleneck.

Use the Llama 3 interruption record without turning job interruptions into device lifetime, predictable failures or a universal spare percentage.

Investigate rising corrected-memory errors without promising a failure prediction, and follow recovery flags and vendor repair criteria.
