Describe

The original cub in cuda11.6 is cub 1.15.0, which has bug as follows:

This problem can be found in NVIDIA forum, and has been fixed in PR #423 (which landed in CUB 1.16.0). So use cub 1.16.0 when cuda version greater_equal 11.6.

Another problem happened after this set because of thrust and cub version not compitable, so add definition just as the cuda error says.
