NVIDIA cuPhoton is an open‑source CUDA‑X toolkit that keeps scientific image data on the GPU from ingestion through classification, providing modules such as xDataReader (direct FITS loading), xRep (alignment), xPois (PSF matching/subtraction), xFit (dipole fitting) and xScan (candidate review). The toolkit achieves up to ~15 000× speed‑ups over CPU baselines, enabling the Vera C. Rubin Observatory’s LSSTCam to process 3.2‑gigapixel exposures (~20 TB/night) and ten million candidates within a 60–120 second alert window on multi‑GPU/multi‑node NVIDIA Grace Blackwell or Vera Rubin systems. Deployment requires cloning the repository, installing CUDA 13, building the xDataReader extension, and following the distributed execution guide for cross‑node GPU scaling.
