A modern, open source remote procedure call (RPC) framework that can run anywhere. It enables client and server applications to communicate transparently, and makes it easier to build connected systems.

OpenColorIO (OCIO) is a complete color management solution geared towards motion picture production with an emphasis on visual effects and computer animation. OCIO provides a straightforward and consistent user experience across all supporting applications while allowing for sophisticated back-end configuration options suitable for high-end production usage. OCIO is compatible with the Academy Color Encoding Specification (ACES) and is LUT-format agnostic, supporting many popular formats.

This package contains files common to all languages and libraries contained in the GNU Compiler Collection (GCC).

Library of vocoder blocks, including ulaw, alaw, gsm and codec2. Debian uses external libraries for gsm and codec2.

Pure Python implementation of bayesian global optimization with gaussian processes. This is a constrained global optimization package built upon bayesian inference and gaussian process, that attempts to find the maximum value of an unknown function in as few iterations as possible. This technique is particularly suited for optimization of high cost functions, situations where the balance between exploration and exploitation is important.

FxT is a library and associated tools that can be used to analyze the performance of multithreaded programs which can potentially use a hybrid thread scheduler (i.e. a user-level scheduler on top of a kernel-level one). The Marcel thread library can take full profit from this library.
