Purpose
CppAD has a set of speed tests that are used to determine if
certain changes improve its execution speed
(and to compare CppAD with other AD packages).
This section links to the source code the CppAD speed tests
(any suggestions to make the CppAD results faster are welcome).
Speed
To run these tests, you must include the
--with-Speed command line option during the
install configure
command.
After the Unix install make
command,
you can then run the CppAD speed tests
with the following commands (relative to the distribution directory):
speed/cppad/cppad correct seed where seed is a positive integer see for the
random number generator uniform_01
.
This will check that the speed tests have been built correctly.
You can run the command
speed/cppad/cppad speed seed to see the results of all the speed tests.
See speed_main
for more options.
C++ Compiler Flags
The C++ compiler flags used to build the CppAD speed tests are
AM_CXXFLAGS = -O2 -DNDEBUG $(CXX_FLAGS) -DCPPAD where CXX_FLAGS is specified by the
configure
command.
