有类似推力推力计算功能？

Question

我想知道是否有一个模拟可以增强计算功能（ http://www.boost.org/doc/libs/1_61_0/libs/compute/doc/html/boost_compute/advanced_topics.html#boost_compute.advanced_topics.custom_functions ）进入内核并可以创建为嵌入式内联代码而变成内核？

In thrust, you can use function/functor with __device__ qualifier. An example of vector operation saxpy is shown in the link, where you could find the functor saxpy_functor

http://docs.nvidia.com/cuda/thrust/#transformations

Similar to boost::compute , you could also use thrust lambda expression as

thrust::transform(X.begin(), X.end(), Y.begin(), Y.begin(), A * _1 + _2);

or more standard C++ lambda expression as shown by @RobertCrovella.
