Applies AFNO to autoregressive high-resolution global weather fields and develops feature/data-parallel GPU training with optimized spectral operations, I/O and launch overhead.
Scientific scope
Applies AFNO to autoregressive high-resolution global weather fields and develops feature/data-parallel GPU training with optimized spectral operations, I/O and launch overhead. Two 2022 sources bundled with separate 13/9-person bylines; SC account shares contribution among Subramanian/Harrington/Pathak, not automatically first author. Forecast speed is inference-only on specific hardware/variables; ERA5 reanalysis/training cost and fewer vertical variables matter. Distributed timings include exposed I/O/validation but exclude setup/warm-up/capture and extrapolate some 80-epoch costs from five epochs. No general climate or exact physical-simulation certificate.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
