Speed optimization over i5/i7 x64 arch:

Compute distance between two vectors of points in 128-D space (128 coordinates). The purpose is to find the maximum distance from any one point.

As a distance, implement L1 (SAD) and L2 (SSD) norm over the 8-bit unsigned data type

Points (out of 10) vs. expected performance (SSD & SAD):

5 for better than 5 & 10 MD/s

6 for better than 10 & 20 MD/s

7 for better than 20 & 40 MD/s

8 for better than 40 & 80 MD/s

9 for better than 60 & 120 MD/s

10 for better than 80 & 160 MD/s
