This is the release of the CUDA 13.3 samples, which include additions for CUDA Tile C++, and updated CCCL and Python samples.
cubDeviceFind - CUB DeviceFind Search Algorithms
Description
This sample demonstrates the three device-wide search algorithms: cub::DeviceFind::FindIf for predicate search, and cub::DeviceFind::LowerBound / UpperBound for parallel binary search. Results are verified against std::find_if, std::lower_bound, and std::upper_bound on the host.
