concept:arithmetic-intensity
Arithmetic Intensity
Arithmetic Intensity in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
GPU-aware training
Keep it fed: loaders and async copies
A fast training step needs an equally deliberate supply chain from storage to pinned memory to the device.
GPU-aware trainingMixed precision without NaNs
Mixed precision is trustworthy only when dtype choices, loss scaling, skipped steps, and quality parity are all observable.
GPU-aware trainingActivations, accumulation, and checkpointing
Checkpointing trades compute for activation memory; accumulation trades update frequency for batch memory—measure and validate each trade separately.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
