Reverse-Engineering NVIDIA Blackwell Tensor Cores for Bit-for-Bit Software Simulation
ycombinator · x · 2026-08-05
A development team has successfully built a software model of NVIDIA Blackwell's Tensor Core MMA instruction that matches the output of real B200 hardware bit-for-bit.
This is not just a numerical approximation, but an exact replication of the underlying logic. The author shares the process of how they reverse-engineered the hardware to achieve this.
