We give a TAF overview and describe in some detail, how iterative solvers can be handled efficiently. As an application we demonstrate the generation of adjoint, tangent linear, and Hessian code for a CFD solver in an airfoil configuration. We also list a few other large-scale applications and their performance.

A feasibility study for our C++ AD-tool. A short 129 C-line Roe solver is differentiated in reverse mode. The automatically generated adjoint code runs about three times slower than the solver itself.

Here we give an overview on how TAF approaches typical challenges of AD such as handling of badly written program code, of large memory/disk requirements, of iterative solvers or of black box routines. We also point out, where the user is required to prepare his program code prior to invoking TAF.

The paper presents a prototype of a Carbon Cycle Data Assimilation System (CCDAS), which is composed of a terrestrial biosphere model (BETHY) coupled to an atmospheric transport model (TM2), corresponding derivative codes as well as a derivative-based optimisation routine. In calibration mode, we use first and second derivatives, to estimate model parameters and their uncertainties from atmospheric observations and their uncertainties. In prognostic mode, we use first derivatives, to map model parameters and their uncertainties onto prognostic quantities and their uncertainties.

Among other things, the paper compares the performance of two sets of derivative code for a test problem. One of these sets is generated by ADIFOR 3 and the other by TAF. The TAF generated adjoint code is by a factor of 5 faster than that generated by the ADIFOR 3.
