Element-wise addition of 2 lists?
...how to do this in pure python. If you want to do this with arrays with 100.000 elements, you should use numpy:
In [1]: import numpy as np
In [2]: vector1 = np.array([1, 2, 3])
In [3]: vector2 = np.array([4, 5, 6])
Doing the element-wise addition is now as trivial as
In [4]: sum_vector = vector1 ...

Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...sult. rsqrtss gives an approximation to the reciprocal, accurate to about 11 bits.
sqrtss is generating a far more accurate result, for when accuracy is required. rsqrtss exists for the cases when an approximation suffices, but speed is required. If you read Intel's documentation, you will also ...
How to print VARCHAR(MAX) using Print Statement?
...could do a WHILE loop based on the count on your script length divided by 8000.
EG:
DECLARE @Counter INT
SET @Counter = 0
DECLARE @TotalPrints INT
SET @TotalPrints = (LEN(@script) / 8000) + 1
WHILE @Counter < @TotalPrints
BEGIN
-- Do your printing...
SET @Counter = @Counter + 1
