XmlPlus xsd2cpp is a tool that compiles an XML schema into C++ data bindings. When invoked on an input XSD file, it generates the C++ sources (implementation/headers) for the supplied XML schema, a main.cpp template to demonstrate how generated sources can be consumed, and the automake/autoconf files for building the generated source.
Elemental is a C++ framework for distributed-memory dense linear algebra that strives to be fast, portable, and programmable. It can be thought of as a generalization of PLAPACK to element-by-element distributions that also makes use of recent algorithmic advances from the FLAME project. Elemental usually outperforms both PLAPACK and ScaLAPACK, however, it heavily relies on MPI collectives so a good MPI implementation is crucial. Both pure MPI and hybrid OpenMP-MPI configurations are supported.
SupplyChain is a C++ library that simulates a supply chain. It takes full advantage of concurrent programming and multi-core CPUs without the programmer having to know anything about it. A supply chain consists of two mandatory components: initial producers and final consumers. Apart from these components, a supply chain can include any number of manufacturer nodes. Each node can contain any number of elements of its own type. These elements allow very powerful supply chains to be modeled and constructed.
libKISSlog is a trivial lightweight C++ template library designed and written according to the KISS (Keep It Simple and Straightforward) principle. It leans heavily on STL for keeping its implementation as simple as its usage, and tries to provide C++ developers with a lightweight, paradigm-pure, and flexible alternative to logging libraries which use design and/or implementation decisions which at least the author of libKISSlog believes to be questionable. Its easiest to explain why libKISSlog would be suitable for your needs by listing the things which libKISSlog does not choose to use or do: no singletons or other forms of mutable global state, no macros, no attempt to fit the Java runtime everything model onto a C++ library, no attempt to be a Java-style (bloated) framework, no attempt to make the choice for you of whether you need thread safety, and no compromise on simplicity in order to facilitate questionable inner-loop logging practices.
