+ A Top-K gating softplus_sqrt written to exploit when the number of experts in
+ the MoE layers are a small power of 2. This allows us to cleanly share the
+ rows among the threads in a single warp and eliminate communication between
+ warps (so no need to use shared mem).
+
+ It fuses the sigmoid, max and argmax into a single kernel.
+
+ Limitations:
+ 1) This implementation is optimized for when the number of experts is a small
+ power of 2. Additionally it also supports when number of experts is multiple
+ of 64 which is still faster than the computing sigmoid and topK separately
+ (only tested on CUDA yet). 2) This implementation assumes k is small, but will
+ work for any k.
