Toward Adjoint OpenMP Michael Förster, Uwe Naumann, Jean Utke AIB 2011-13

Shared-memory multiprocessing is becoming increasingly important in high-performance scientific computing. Algorithmic differentiation provides accurate derivative values and better runtime performance of the adjoint model compared with finite differences. This paper presents a source-to-source transformation of OpenMP augmented code that can be used in source transformation tools for creating the adjoint code of a given input code. Only some directives of the OpenMP standard are considered here, namely, directives to parallelize loops.
