[ADOL-C] using adolc with openmp

[Andrea Walther]

Hi Ian,

so far, it is not possible to create the tape only on thread and
to distribute it subsequently.

However, what does work is the following scenario:

You create the tape one each threat like in the example libprpar.cpp
in the examples directory of ADOL-C.

Subsequently you can then change the values of the variables on each 
thread to evaluate the different instances of your problem.

Hope this helps.

Best regards

Andrea
