The Fortran part seems to be hadsm3um_4.12 so that's probably the scientific core but hadsm3_4.12 looks more like C/C++

hadsm3_4.12 has some 3rd party libraries (not all of them in public domain like InfoZip) in it but the source is most likely property of the CPDN project.

My idea was not to make the complete project free source, just those modules that probably cause technical trouble and are property of CPDN



edit: my fortran knowledge is outdated and not very deep anyway - but C I'm experienced with :-)

the model itself (i.e. the "science" of CPDN) is all Fortran, but there is quite a bit of C++ as well (the BOINC, controlling bits etc). It seems like somehow on the Mac the zip file lib I am using isn't closing properly, so it's something we'll have to investigate as we do the sulphur cycle & coupled model releases, and hopefully have a fix for hadsm3.

Thanks Carl.

As another BOINC volunteer developer I'd definitely second Ananas's suggestion.

Obvious candidates are the controller program's interface with the BOINC core client, trickle processing/credit allocation on the server and the web pages.
