3.18.4 Compiling

The optimization experiment requires two executables: 1) the MITgcm and its adjoint (mitgcmuv_ad) and 2) the line-search algorithm (optim.x).

3.18.4.1 Compilation of MITgcm and its adjoint: mitcgmuv_ad

Before compiling, first note that, in the directory code_ad/, two files must be updated:

  • code_ad_diff.list which lists new subroutines to be compiled by the TAF software (cost_temp.F and cost_hflux.F here),

  • the adjoint_hfluxm files which provides a list of the control variables and the name of cost function to the TAF software.

Then, in the directory build_ad/, type: 

% ../../../tools/genmake2 -mods=../code\_ad -adof=../code\_ad/adjoint\_hfluxm
% make depend
% make adall
to generate the MITgcm executable mitgcmuv_ad.

3.18.4.2 Compilation of the line-search algorithm: optim.x

This is done from the directories lsopt/ and optim/ (under MITgcm/). In lsopt/, unzip the blash1 library adapted to your platform, and change the Makefile accordingly. Compile with: 

% make all
(more details in lsopt_doc.txt)

In optim/, the path of the directory where mitgcm_ad was compiled must be specified in the Makefile in the variable INCLUDEDIRS. The file name of the control variable (xx_hfluxm_file here) must be added to the name list read by optim_num.F. Then use 

% make depend
and 
% make
to generate the line-search executable optim.x.
