The software package MODOI (MOlecular Dynamics Over Ip), an implementation of the Birkhoff curve shortening procedure as a string method for Molecular Dynamics, is online. It is written by Daniel Sutton, funded by
grant EPSRC EP/K027743/1.
There is a simpler version of the code available, online, also written by Daniel Sutton and funded by
EPSRC grant EP/K027743/1. The difference between the codes is that MODOI is an implementation of the Birkhoff
method using TCP/IP to distribute tasks over networked devices (rather than requiring HPC facilities). The
second code, GeometricMD, is a stripped down version of MODOI, designed for HPC; it uses all the cores of the
machine it runs on. So both codes implement exactly the same algorithm and only differ in the way they
A barebone implementation is scikit-geodesic, see the documentation.
