ADIFOR 2.0 NOW AVAILABLE
The ADIFOR 2.0 automatic differentiation system is now available for non-commercial research and commercial evaluation. ADIFOR, which has previously been available only on a limited basis, focuses on the automatic differentiation of Fortran.
When given a Fortran 77 source code and a user's specification of dependent and independent variables, ADIFOR generates 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.
The ADIFOR 2.0 system consists of the ADIFOR 2.0 preprocessor, the ADIntrinsics 1.0 intrinsic handler system, and the SparsLinC 1.0 (Sparse Linear Combination) library. It offers full Fortran 77 support, flexible handling of Fortran intrinsics, and transparent sparsity support.
The ADIFOR project was started in 1991 as a collaboration directed by Chris Bischof at Argonne National Laboratory and Alan Carle at Rice University. George Corliss (Marquette University), Andreas Griewank (University of Dresden), Paul Hovland (University of Illinois), and Peyvand Khademi and Andrew Mauer of Argonne National Laboratory have made fundamental contributions to the development of ADIFOR. The program's development has been funded by the Department of Energy, NASA, and the National Science Foundation.
ADIFOR is not in the public domain, but it is available for non- commercial use or evaluation for commercial purposes free of charge over the World Wide Web. To obtain the ADIFOR 2.0 system or related documentation and reports, visit the ADIFOR web sites at http://www-unix.mcs.anl.gov/autodiff/ADIFOR/ or http://www.cs.rice.edu/~adifor .
