# GPU Bundle Adjustment Against Ceres Solver

Large Photogrammetry Problems Reach Ceres's Final Cost Several Times Faster.

24.5 s vs 168 s dubrovnik-356 to Ceres cost

2.2 s vs 4.7 s final-93

32 Ceres threads

small problems where Ceres is faster

- GPU Levenberg-Marquardt with implicit Schur complement PCG on BAL; Ceres 2.2 with 32 threads
- dubrovnik-356: Ceres's final cost in 24.5 s vs 168 s, and a lower final cost (491,384 vs 493,850)
- final-93: 2.2 s vs 4.7 s
- Ceres is faster on small problems (under ~2 s), trafalgar-257 and venice-52
