In the sources

• “One factoid that may be useful is that NVLink-Sharp in-switch reductions are deterministic on Blackwell as well as Hopper with CUDA 12.8+.”

• “This is also even different from what we had 2 years ago where there was a supply crunch for hopper generation chips in 2023 2024. Uh in that period it was all training oriented spend and training is inherently speculative.”

In the claim ledger

2 promoted claims tagged with this work. Assessments are the model’s knowledge, not verification.

• FP8 GEMM accumulation on H800 Tensor Cores retains only about 14 bits, far below FP32.

  consistent · DeepSeek-V3 Technical Report

• The authors recommend that future accelerators implement higher-precision FP8 GEMM accumulation in hardware.
