Lab
Things I’m learning and experimenting with. These are learning notes, not credentials: they record what I tried, in what environment, and what I still don’t know. Anything exploratory lives here and nowhere else on the site.

An ops engineer's first map of GPU clusters: capacity, drivers, interconnects, topology, storage, schedulers, monitoring, failure modes and cost. Learning notes, not experience.
