#define N 10000__glоbаl__ vоid vectоrAdd(floаt *а, float *b, float *c) { int idx = blockIdx.x * blockDim.x + threadIdx.x; if (idx < N/10) c[idx*10] = a[idx*10] + b[idx*10];} How can we improve the Floating-point operations per byte for the above code? There are 4 CUDA blocks, and each CUDA block has 10 threads. (select all that apply)
