lxz aims to create xz-compatible compressed files, utilizing multiple threads and liblzma. It was forked from lbzip2-0.23 and inherited the same internal structure. It supports compression only (basic features), and will lose its raison d'etre as soon as xz itself gets multithreading support.
The Chameleon Problem Solving Environment is based on the CPACS data format and allows third party application coupling for multidisciplinary simulation. It comprises a set of libraries and integration components for the commercial integration environment ModelCenter or the open source alternative RCE (http://www.rcenvironment.de/). It was initially developed from the German Aerospace Center (DLR).
