MCT and ARPACK

[mathieu]

ROMS comes with included MCT and ARPACK libraries. What is the reason for that?
Is it for convenience so that we can compile it easily or were there some modifications to the code?
If so, what were those modifications?

[kate]

ROMS is a complex beast. The ocean-only forward model uses neither library, but the coupled wave model uses MCT and the adjoint package uses ARPACK.

[arango]

Yes, Users needing the ARPACK/PARPACK libraries in the adjoint-based algorithms need to use the provided libraries in the Lib/ARPACK directory. We had to make changes and additions to these libraries to allow check-pointing.

Ok, so ARPACK has been modified. But are those modifications documented?
Has MCT been modified as well? Will those modifications be included in current distribution of those softwares?
