Scalable Stellar Parameter Inference Framework
Analysis
Key Takeaways
- •Significant runtime improvements achieved through CPU optimization and GPU acceleration.
- •Framework validated against existing methods and applied to large spectroscopic surveys (LAMOST, DESI).
- •Demonstrates reliable accuracy and transferability for stellar parameter inference.
- •Code and a DESI-based catalog are publicly available.
“The framework reduces runtime from 84 to 48 hr on the same CPU platform and to 7 hr on an NVIDIA A100 GPU, while producing results consistent with those from the original pipeline.”
