The typical invocation specifies the execution policy as follows: thrust::inclusive_scan(thrust::device, d_input, d_input + data_size, d_output); By passing thrust::device as the first argument, the compiler resolves this to the CUDA backend implementation defined in the library's system headers. The entry point typically looks like this: tem ...

A kernel is a function that, when called, is executed N times in parallel by N different CUDA threads, as opposed to a regular C++ function which executes only once.
