Speed Test Derivatives Using Fadbad

Purpose

CppAD has a set of speed tests that are used to compare Fadbad with other AD packages. This section links to the source code the Fadbad speed tests (any suggestions to make the Fadbad results faster are welcome).

fadbad_prefix

To run these tests, you must include the fadbad_prefix in you CMake Command .

Running Tests

To build these speed tests, and run their correctness tests, execute the following commands starting in the Build Directory :

      cd speed/fadbad

      make check_speed_fadbad VERBOSE =1

You can then run the corresponding speed tests with the following command

./ speed_fadbad speed seed

where seed is a positive integer. See speed_main for more options.
