[Omp] CppAD + OpenMP volunteers

[Brad Bell]

I have been working on making the algorithmic differentiation package CppAD
    http://www.coin-or.org/CppAD/
work well with OpenMP.

In an effort to do so, I have created some preliminary speed test cases; 
see the Example heading in
    http://www.coin-or.org/CppAD/Doc/omp_max_thread.xml
If your browser does not support XHTML + MathML, you can view the *.htm 
instead of *.xml files; e.g.,
    http://www.coin-or.org/CppAD/Doc/omp_max_thread.htm

I found some volunteers from the CppAD user community to run these 
timing tests, but I do not understand why we do not get the speed up I 
expect. I am looking for volunteers in the OpenMP community to run these 
tests, help understand the result, and possibly help improve how CppAD 
interacts with OpenMP.

A volunteer would first have to download (but not have to install) CppAD 
as per the instructions at
     http://www.coin-or.org/CppAD/Doc/installunix.xml
and then use (and possibly need to modify) the openmp/run.sh script
    http://www.coin-or.org/CppAD/Doc/openmp_run.sh.xml
to run the timing tests.
