Line 86 should read:
cudaMemcpy(host_array_c, device_array_c, num_bytes, cudaMemcpyDeviceToHost);
Instead of:
cudaMemcpy(host_array_c, device_array_c, num_elements,
cudaMemcpyDeviceToHost);
If you augment the current code to print the last few elements of the
result vector, you'll see they're currently all zero -- only the first
quarter of the output vector is copied from the device (assuming 4-byte float).

I believe line 80 should read:
if(num_elements % block_size) ++grid_size;
instead of the current:
if(grid_size % block_size) ++grid_size;
In other words, add an extra block to the grid if the total number of
elements isn't evenly divided by the block size.
