ADIFOR Software

ADIFOR was the winner of the 1995 Wilkinson Prize for groundbreaking contributions to numerical computing.

About ADIFOR

ADIFOR is an exceptional technology developed under a collaboration between Argonne National Laboratory and Rice University encompassing more than 10 years of effort.

ADIFOR employs a technique called automatic differentiation to generate derivative-enhanced versions of programs written in Fortran 77. AD is applicable to a wide variety of scientific and engineering areas. Present applications include weather prediction, aerospace vehicle optimization, earthquake ground modeling, nonlinear structural analysis, chemical reactor modeling, medical drug modeling, waste site and ground water flow characterization, and hydrodynamic modeling. Ongoing developments include the differentiation of ANSI-C, the computation of higher-order derivatives, and the computation of "adjoints." ADIFOR is available for the following operating systems: AIX, SunOS 4.x and 5.x, HP/UX, IRIX, Linux, and Windows 95/NT.
