Title: New features in CoDiPack – Linear system handling and basic algorithm support


Linear system handling: CoDiPack now provides a helper for handling linear system solvers on the tape. The user has to implement a few functions for CoDiPack and then the linear system solve is automatically added to the tape. We will present the implementation details and how the helper can be used in software.

Algorithm support: Algorithmic Differentiation can be used to implement design optimization with the adjoint calculus. One algorithm the sensitivity computation is the reverse accumulation algorithm. A new module in CoDiPack provides implementations of the reverse accumulation algorithm and many others. A user has to implement an application interface that is used by the algorithms. We will present the implementation details, the interfaces, and the current set of algorithms and their properties.
