Fsdp

Fsdp in the context of production machine-learning systems.

Lessons

Formal explanations, examples, simulations, and checkpoints.

Distributed checkpoints and fault-tolerant restarts

Checkpoint correctness is next-step equivalence, protected by complete state, atomic publication, and rehearsed recovery.

Distributed & fault-tolerant training

Hangs, stragglers, and scaling efficiency

Distributed speed is synchronized speed: diagnose the first divergence, measure the slowest rank, and scale against quality and cost—not worker count.

Courses & assignments

Dependency-authoritative learning units.

Casebook

Reported facts and course reconstructions.
