ADIFOR: Automatic Differentiation of Fortran 77
ADIFOR (AD) is a tool for the automatic differentiation of Fortran 77 programs. Given a Fortran 77 source code and a user's specification of dependent and independent variables, ADIFOR will generate an augmented derivative code that computes the partial derivatives of all of the specified dependent variables with respect to all of the specified independent variables, in addition to the original result.
AD is applicable to a wide variety of scientific and engineering areas including weather prediction, aerospace vehicle optimization, earthquake ground modeling, nonlinear structural analysis, chemical reactor modeling, medical drug modeling, waste site and ground water flow characterization, hydrodynamic modeling, the differentiation of ANSI-C, the computation of higher-order derivatives, and the computation of "adjoints."
Argonne and Rice University collaborated to develop ADIFOR.
