Speed Test an Operator Overloading AD Package

Purpose

Cppad has a set of speed tests that are used to determine if changes improve its execution speed. These tests can also be used to compare the AD packages Adolc , Cppad, Fadbad , Cppadcg , Sacado .

debug_which

Usually, one wants to compile the speed tests in release mode. This can be done by setting cppad_debug_which to debug_none in the cmake command. Correctness tests are included for all the speed tests, so it is possible you will want to compile these tests for debugging; i.e., set cppad_debug_which to debug_all .

The sections below explain how you can run these tests on your computer.
