Data type support

hipCUB supports the following data types on both ROCm and CUDA:

• int8

• int16

• int32

• float32

• float64

float8, bfloat8, and tensorfloat32 are not supported by hipCUB on neither ROCm nor CUDA.

The NVIDIA back end does not support float16 nor bfloat16 with the following API calls: block_adjacent_difference, device_adjacent_difference, device_reduce, device_scan, device_segmented_reduce and device_select.

The NVIDIA backend also does not support bfloat16 with device_histogram.
