Fp16 Bf16
Fp16 Bf16 in the context of production machine-learning systems.
Lessons
Formal explanations, examples, simulations, and checkpoints.
GPU-aware training
Activations, accumulation, and checkpointing
Checkpointing trades compute for activation memory; accumulation trades update frequency for batch memory—measure and validate each trade separately.
GPU-aware trainingProfile from timeline to cost per sample
Profile a controlled workload, explain the timeline, and judge improvements by cost to an unchanged quality target.
Courses & assignments
Dependency-authoritative learning units.
Casebook
Reported facts and course reconstructions.
