getdns is a modern asynchronous DNS API. It implements DNS entry points from a design developed and vetted by application developers, in an API specification edited by Paul Hoffman. This API intends to offer application developers a modernized and flexible way to access DNS security (DNSSEC) and other powerful new DNS features; a particular hope is to inspire application developers towards innovative security solutions in their applications.

Gerris is a system for the solution of the partial differential equations describing fluid flow.

This is a modular parallel C++ library for finite element methods. Its goal is to enable high-performance scalable finite element discretization research and application development on a wide variety of platforms, ranging from laptops to supercomputers.

mimetic is a MIME library written in C++ designed to be easy to use and integrate but yet fast and efficient.

mmlib is the general purpose library providing helper functions to other module. It provides a cross-platform OS abstaction layer as well as facilities like logging or error reporting.

Provides C++ API for creating molecular models whose dynamics can be simulated using the SimTK Simbody library. Molmodel is a programmer's toolkit for building reduced-coordinate, yet still all-atom, models of large biopolymers such as proteins, RNA, and DNA. One can control the allowed mobility. By default, Molmodel builds torsion-coordinate models in which bond stretch and bend angles are rigid while bond torsion angles are mobile. But one is able to rigidify or free any subsets of the atoms, such as the rigid benzene ring.
