Can global function be member of a class?
The CUDA programming guide only says (section D.2.5.2) that global functions cannot be static members. However, when I try non-static global function, I get “illegal combination of memory qualifiers” error (CUDA 4.0 RC2).
class A { public: __global__ void ker(int n, float* a, float* b); }; __global__ void A::ker(int n, float* a, float* b) { int t = blockIdx.x * blockDim.x + threadIdx.x; if ( t < n ) a[t] += b[t]; }
