Third bit-level Tensor Core model in a row broken by same pair of testcases
i_komarov · x · 2026-09-27
The author reports that yet another bit-level Tensor Core model has been broken by the exact same pair of testcases — the third in a row, suggesting a common weakness in NVIDIA's Tensor Cores. A reply suggests the accumulation grid resolution may become too fine as a cause. The author also recommends two battle-tested open-source repos for learning how NVIDIA Tensor Cores work, noting the accompanying papers cover largely the same material, likely because both author groups started around the same time last year.
