Problem

Cub allows itself to place into a namespace via CUB_NS_PREFIX and CUB_NS_POSTFIX, such that multiple shared libraries can each utilize their own copy of it (and thus different versions can safely coexist). Static variables used for caching could otherwise cause problems (e.g., https://github.com/NVIDIA/cub/blob/main/cub/util_device.cuh#L212).

Thrust however depends on cub and

DeviceSegmentedReduce reduces each segment using the same kernel as DeviceReduce, and thus provides the same run-to-run consistency guarantee for non-associative types. The documentation for DeviceSegmentedReduce should be updated to reflect this.

E.g. this bit: https://github.com/NVIDIA/cub/blob/a8910accebe74ce043a13026f8e71d678cddd6c1/cub/device/device_reduce.cuh#L91-L95

Add Runnable links of the code below the example.
Use link name Run Code which links to a Online C++ complier conatining the example code.
Use Rextester as the Online C++ Compiler (If you have a better suggesstion please comment).

Follow below steps to generate the Run Code Link.

1. Go to Rextester
2. Copy or write the example
