Notes:
- Units - CPE (Clocks per Element)
Performance was measured on "working" interval (double precision: [ 0.01, 20.0 ] × [ 0.01, 20.0 ]; single precision: [ 0.01, 20.0 ] × [ 0.01, 20.0 ])
Data - vectors of 1000 elements with random generated numbers.
All data was collected with 64-bit libraries.
