Alphabetical List of tools

  • ADF  ( Fortran77,Fortran95 )
    The vivlabs ADF Automatic Differentiation Software for FORTRAN delivers rapid integration of automatic differentiation capability to your new and existing applications on all operating system platforms. ADF automatically exploits the sparsity within your equation matrices, which leads to winning performance for both small, large and extremely large applications.

  • ADG  ( Fortran 77/90,Fortran77,Fortran95 )
    The Adjoint Code Generator (ADG) is a source-to-source transformation tool that is used for generating the adjoint model. Designed with the Least Program Behavior Decomposition Method, ADG supports global data dependent analysis and code optimization at a statement class.

  • ADIFOR  ( Fortran77 )
    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.

  • AUTO_DERIV  ( Fortran77,Fortran95 )
    AUTO_DERIV is a Fortran 90 module which can be used to evaluate the first and second derivatives of any continuous function with any number of independent variables. The function can be implicitly encoded in Fortran 77/90; only slight modifications in user code are required.

  • COSY INFINITY  ( Fortran77,Fortran95,C/C++ )
    COSY is an open platform to support automatic differentiation, in particular to high order and in many variables. It also supports validated computation of Taylor models. The tools can be used as objects in F95 and C++ and through direct calls in F77 and C, as well as in the COSY scripting language which supports dynamic typing.

  • DFT  ( Fortran 77/90,Fortran77,Fortran95 )
    DFT is a source-to-source transformation tool for generating the tangent linear model, and it supports global data dependent analysis and code optimization at a statement class.

  • FortranCalculus Compiler  ( Fortran77 )
    FortranCalculus (FC) language is for math modeling, simulation, optimization, and parameter tweaking. FortranCalculus is based on Automatic Differentiation (AD) and Operator Overloading that simplify computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand and not on the (numerical) process requirements to achieve an optimum solution. There are some 100+ example math problems from industry in the 'demo' section for users to browser, run, and copy for building their own math problem. At least for the next year or two, FC-Compiler is free! Try it, you'll like it.

  • GRESS  ( Fortran77 )
    GRESS (Gradient-Enhanced Software System) reads an existing Fortran code as input and produces an enhanced Fortran code as output. The enhanced code has additional new lines of coding for calculating derivative information analytically but using the rules of calculus. The enhanced model reproduces the reference model calculations and has the additional capability to compute derivatives and sensitivities specified by the user. The user also specifies whether the direct or adjoint method is to be used in computing sensitivities.

  • NAGWare Fortran 95   ( Fortran77,Fortran95 )
    The NAGWare Fortran 95 Compiler is being extended to provide AD functionality. The first prototype will be distributed to beta testers by November 2002.

  • OpenAD  ( C/C++,Fortran77,Fortran95 )
    OpenAD is a source transformation tool that provides a language independent framework for the development and use of AD algorithms. It interfaces with language specific front-ends via an XML representation of the numerical core. Currently, Open64 is the front-end for FORTRAN and EDG/Sage3 the front-end for C/C++.

  • PCOMP  ( Fortran77 )
    PCOMP implements the forward and reverse mode for functions written in a FORTRAN-like modeling language, a subset of FORTRAN with a few extensions. First- and second-order derivatives are supported.

  • TAF  ( Fortran 77/90,Fortran2003,Fortran2008,Fortran77,Fortran95 )
    Transformation of Algorithms in Fortran (TAF) is a source-to-source AD-tool for Fortran-95 programs. TAF supports forward and reverse mode of AD and Automatic Sparsity Detection (ASD) for detection of the sparsity structure of Jacobians.

  • TAMC  ( Fortran77 )
    TAMC is a source-to-source AD-tool for FORTRAN-77 programs. The generated code propagates derivatives in forward (tangent linear) or reverse (adjoint) mode. TAMC is very flexible thanks to many options and user directives.

  • TAPENADE  ( C/C++,Fortran77,Fortran95 )
    TAPENADE is a source-to-source AD tool. Given a FORTRAN77, FORTRAN95, or C source program, it generates its derivative in forward (tangent) or reverse (adjoint) mode. TAPENADE is the successor of ODYSSEE. TAPENADE is directly accessible through a web servlet, or can be downloaded locally.

  • Treeverse / Revolve  ( C/C++,Fortran77,Fortran95 )
    Revolve implements an efficient checkpointing algorithm for the exact computation of a gradient of a functional consisting of a (pseudo) time-stepping procedure.
