Thrust
thrust::transform_reduce(thrust::device, ... flow is the following:
thrust::transform_reduce(thrust::device, ...
get_value
The cudaStreamSynchronize in step 3 is unnecessary when get_value is going to perform a stream-ordered operation and synchronize.
This was discovered in TeaLeaf and impacts std::transform_reduce performance.
std::transform_reduce
Use the transform reduce algorithm on trivial types on device memory or unified memory.
No unnecessary cudaStreamSynchronize.
