C-tracker

A Lagrangian particle tracker for hydrodynamic numerical simulations. It is written in python 3.6 with the numerical parts using cython. The numerical part reproduces the results of tracmass code (https://github.com/TRACMASS/tracmass) by Döös et al., despite some (relatively minor) changes in the algorithm. It is developed for use with MITgcm results, but any C- (or B-) grid model could be used as a source for the hydrodynamic fields.

To install:

python setup.py build_ext --inplace

For using non-default compilers, use e.g:

LDSHARED="icc -shared" CC=icc python setup.py build_ext --inplace

For intel C compiler, a good set of options is:

LDSHARED="icc -shared" CC=icc CFLAGS="-O3 -xHOST -ipo -static -fp-model source" python setup.py build_ext --inplace

It seems that the results are very stable to aggressive optimization.
