Research direction

Start by locating OpenSfM's bundle-adjustment entry point and its Ceres solver configuration, then compare that integration with the Ceres 2.1 CUDA installation described in the linked documentation. Determine what configuration or integration change would make bundle adjustment use the CUDA-enabled solver and how that behavior could be verified.
