You can remove this function and the functions it calls from this file: no need to port it to gpu.

Can we port this to cub::DeviceRadixSort as well?
- Code compiles and a test in tests/cuv_sort.cu outputs a correct answer HACK: combined Topkey, key into a single unit64_t. - This is to avoid using a struct with two uint32_t members. Which is not supported by cub::DeviceRadixSort::SortPairs. - TODO: use `thrust::sort_by_key` instead of `cub::DeviceRadixSort::SortPairs`
