The first is a model of nanotube vibrations from a project co-supervised by Yuval Yaish, is not memory bound, at least for now. It is mainly complicated by the need to run the same code for many different parameters and by an enormous load of fourier transfom analysis. We may call this a bookeeping bound project.
The second project is severely memory bound and also somewhat time bound It is the start of a project on HCP crystal melting which is being co-supervised by Emil Polturak and also a test of NANCO's capabilities. The sample sizes needed are way beyond those that can be modeled on a few procesors, hence the speedup is calculated for small samples on a few processors and for larger ones on more processors.
