Arg

Computes the argument of vector elements.

Performance:

  Intel® Xeon® Processor E5-2680 Intel® Xeon® Processor E5-2699 v3 Intel® Xeon® Processor E5-2699 v4 Intel® Xeon® Gold 6148 Processor

Notes:
  1. Units - CPE (Clocks per Element)

  2. Performance was measured on "working" interval (double precision: [ -10000.0, 10000.0 ] × [ -10000.0, 10000.0 ]; single precision: [ -10000.0, 10000.0 ] × [ -10000.0, 10000.0 ])

  3. Data - vectors of 1000 elements with random generated numbers.

  4. All data was collected with 64-bit libraries.
