I am trying to implement a simple calculation algorithm on a GPU (GTX 295).
Because I need very good accuracy, I am using double precision.
I wanted to know if nvcc is using GPU native/intrinsec exp and log functions (in double precision) if I compile a code like that (in the kernel):
R[index] = exp(Y[index])+log(U[index]);
Of course, I am using -arch sm_13 and -O4 when compiling, and R,Y,U are double type arrays.
Thanks in advance :)
