M1T2 — Build an empirical roofline¶
Run the default sweep:
The script writes results/latest.json and results/roofline.png. Supplying both ceilings creates a hardware roofline; omitting them creates an empirical roofline from this process. The success criterion is that you can classify every point on the memory- or compute-limited side of the ridge and explain why small GEMMs sit below either ceiling.
