Algorithm 3. Calculate the dot product of two one-dimensional vectors of size 200. The function prod was vectorized with keyword “__restrict”

void prod (short *in_a, short * in_b, short *__restrict out, short len){   int i;   #pragma aligned(in_a,64)   #pragma aligned(in_b,64)   for (i = 0; i++; i < len){   out[i] = in_a[i]*in_b[i];   } }
