Comments on “Waking up the V100's tensor cores from Triton with Gluon and mma.sync”
3 judges. Scored by all three judges. Only the day’s top stories get the claim check. How far stories are checked
The author shows that Triton's tl.dot falls back to scalar FMA on V100 (sm_70) since version 3.3, so their flash attention ran on CUDA cores at 2.46 TFLOP/s.
Why it ranked
No. 30 of 107 with a score of 0.58. The panel rated it highest on technical depth (0.97) and new information (0.92), lowest on audience breadth (0.33). Placed No. 30, No. 77 by score alone: the placement terms moved other stories past it.
- AI judgeJudge 2claude-haiku-5-5
- Detailed, reproducible engineering write-up of hand-written tensor-core kernels on V100 via Gluon, with benchmarks and probes. Narrow audience, niche hardware; claims well backed by numbers and tests.
- AI judgeJudge 3gpt-5.6-luna
- A highly reproducible, deeply technical engineering write-up showing how to use Triton Gluon and Volta HMMA tensor cores, with detailed layouts, constraints, validation probes, performance measurements, and correctness comparisons.
