This page provides download links for a set of curricular materials designed to teach parallel computational modeling to undergraduate or graduate students in science and other STEM disciplines. The module begins with the construction of a cellular automaton model of microbial biofilms using Mathematica. This model is then re-implemented with C and parallelized using MPI. The module consists of the documents described below. The documents can be downloaded individually, or as a zip archive containing all of the documents:


Biofilms Module.doc : MS Word file describing:
