From the source SKILL.md

A checkpoint for a 70-billion-parameter run is hundreds of gigabytes spread across every rank. Save it naively and each write stalls all GPUs for minutes while they push through a shared filesystem, so people checkpoint rarely and lose a whole shift of compute when one node dies. The method makes saves cheap and resumes trustworthy.

What this skill does

Checkpointing Large Training is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/checkpointing-large-training/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when a job is large enough that a crash without a recent, verified checkpoint means losing hours of GPU time.
