FP8 Debunks FP64 as HPC Holy Grail in New Paper from Satoshi Matsuoka
A new arXiv preprint by Satoshi Matsuoka challenges the long-held belief that native FP64 hardware is essential for high-performance scientific computing. The paper proposes that FP8 tensor-core operations, combined with the Ozaki Scheme II, can deliver equivalent double-precision accuracy, reducing FP64 from a hardware requirement to a derived guarantee. The analytical framework is tested across a five-layer hierarchy, projecting improved performance on upcoming NVIDIA GPUs.
