Notes:
- Units - CPE (Clocks per Element)
- Performance was measured on "working" interval (double precision: [ 0.1, 10000.0 ] for HA and LA, [ 1.2, 10000.0 ] for EP; single precision: [ 0.1, 10000.0 ] for HA and LA, [ 1.2, 10000.0 ] for EP)
- Data - vectors of 1000 elements with random generated numbers.
- All data was collected with 64-bit libraries.
