Bullet 1:
Significance (quantitative): ... For a 7B-parameter model on H100 (R_peak = 312 TFLOPS)
It should be A100, as H100 peak TFLOPS is 1,979 .
Expected Behavior
For a 7B-parameter model on A100 (instead of H100)

Coincidentally, I just fixed this in my local dev because I was rewriting the mlsysIM (https://mlsysbook.ai/mlsysim) to fix issues -- it's basically the calculator for the book, and I needed to refactor it, so I will resolve the issue in there and ping you when its pushed live, which will happen in a few days. I've been cleaning up a lot of things.
Appreciate your help!

Thanks again @tddg. This is now fixed. As part of the mlsysIM refactor, the Computing Infrastructure chapter no longer hardcodes accelerator specs; the A100 and H100 numbers are pulled directly from the hardware zoo. The old definition that mislabeled the 312 TFLOPS FP16 peak as H100 has been rewritten, and 312 TFLOPS is now correctly attributed to the A100 throughout. The change is merged to main and will carry into the next release. Closing this out.
