GRESS adjoint matrix reduction algorithms
Description
GRESS is an efficient automated software system for calculating sensitivities of model results to input data in existing FORTRAN 77 computer models. The GRESS ADGEN option calculates first derivatives of selected model results with respect to an almost unlimited number of data by applying the adjoint method; however, data storage has been a major limiting factor. The data storage requirement for an ADGEN application was more than 322 Mbytes for a code that executes in 1 min on a VAX 8600 computer. The purpose of this paper is to describe two new algorithms that dramatically reduce the data storage requirement and execution time for application of the ADGEN option
