The D2AR framework enables exascale training of a generative compression model using historical Earth observation data as learned priors. It achieves up to 10,000x data reduction while reconstructing critical physical information for various scientific tasks.
Key insights
- Global historical Earth observation archives can be transformed into active, task-adaptive generative priors, enabling high-fidelity data reconstruction from extremely compressed signals.
- A physically decoupled architecture, using lightweight sensor-specific adapters with a unified generative backbone, ensures cross-modality consistency and simplifies core generative computation.
- System-level co-optimization across model design, kernel implementation, memory management, and parallelization is critical for achieving high sustained performance on CPU-centered exascale supercomputers for scientific AI workloads.
