## Executive Summary
We ported ThunderKittens to NVIDIA's Vera Rubin NVL72 and rebuilt our NVFP4 GEMM around the new hardware, taking it from 42% of roofline to over 22 PFLOPS - competitive with cuBLAS and CuTe DSL. Here is what changed in the ISA and how we used it.

## Why It Matters (Strategic Analysis)
The work proves that targeted kernel redesign for a new GPU ISA can extract near‑peak compute throughput, closing the performance gap between open‑source and vendor‑optimized libraries.
