CUDA same function for CPU and GPU
c, c++, cuda, gpgpu
Solution
You just have to add the `__host__` keyword to be able to call call a function from host or device.
__host__ __device__ int sum(int a, int b){
return a+b;
}
Problem
In order to call the same function from host code and GPU kernel, Do I have to keep the two copies of the same function as below: ``` int sum(int a, int b){ return a+b; } __device int sumGPU(int a, int b){ return a+b; } ``` Or is there any technique to keep/manage a single copy of the function?
