Training run — cost & time

Estimate a training run end to end: model parameters and tokens (6·P·T FLOPs), MFU, cluster size, and goodput → wall-clock days, GPU-hours, rental cost, facility energy, and emissions.

MFU and goodput compound: a 40% MFU × 90% goodput scenario yields 36% of peak theoretical FLOPs as committed training work under the declared definitions. Treat 90% versus 96% only as an illustrative sensitivity; measure the named fleet, job, window, and event accounting, then attribute badput before assigning any gap to checkpointing or cordon policy → Ch 12.2.
