Computational Differentiation

The computational differentiation group develops technologies for generating, with minimal human effort, efficient derivative code for models implemented as computer programs. These technologies include compiler-based automatic differentiation tools, new differentiation strategies, and Web-based differentiation services. The research is guided by collaborations with scientists from a variety of application domains:

• Application of ADIFOR to advanced three-dimensional computation fluid dynamics (CFD) codes to compute sensitivities for use in multidisciplinary design optimization
• AIF: a language-neutral AD Intermediate Form for ADIFOR and ADIC
• New front end for ADIC, based on a C/C++ front end from Edison Design Group
• Integration of ADIC/ADIFOR with PETSc/TAO/PVODE
