# 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.

|
|
cub::DeviceFind::FindIf, cub::DeviceFind::LowerBound, cub::DeviceFind::UpperBound
|
|
|
|
### [CCCL libcu++](https://nvidia.github.io/cccl/unstable/libcudacxx/index.html)
|
|
|
|
cuda::std::less
|
|
|
|
### [CUDA Runtime API](http://docs.nvidia.com/cuda/cuda-runtime-api/index.html)
|

|
|
|
|
## Dependencies needed to build/run
|
|
|
|
[CCCL 3.3+](https://github.com/NVIDIA/cccl). Fetched automatically via CPM at configure time (pinned to `v3.3.3`). Override with `-DCCCL_SOURCE_DIR=/path/to/cccl` to use a local checkout.
|
|
|
|
## Prerequisites
|
|
|
|
Download and install the [CUDA Toolkit](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
|
|
Make sure the dependencies mentioned in [Dependencies]() section above are installed.
