FastFlow is a pattern-based programming framework targeting streaming applications. It implements pipeline, farm, divide and conquer, and their composition, as well as generic streaming networks. It is specifically designed to support the development and the seamless porting of existing applications on multi-core, GPGPUs, and clusters of them. The layered template-based C++ design ensures flexibility and extendibility. Its lock-free/fence-free run-time support minimizes cache invalidation traffic and enforces the development of high-performance (high-throughput, low-latency) scalable applications. It has been proven comparable or faster than TBB, OpenMP, and Cilk on several micro-benchmarcks and real-world applications, especially when dealing with fine-grained parallelism and high-throughput applications.
lrc (The Linux Resource Compiler) is a system for packing many files into a single file for installation and use in a program as its resources (such as the graphics and sounds used by a game). It consists of a command-line tool, called lrc, for compiling the resources and a library, called liblrc, to extract the resources from a file generated by the compiler.
libsockmux-glib is an implementation of the sockmux protocol, using GIO data types and using glib functions internally. The interface offered to applications is very simple and straightforward. sockmux specifies a simple way for muxing messages and data streams onto a single socket for network and local communication streams.
WikiPL provides a Python programming environment hosted in a MediaWiki server. Each article in the wiki contains either a Python function or a class named as the article's title. Moreover, the article can contain the source code, documentation, unit tests, development edition, permissions, and form elements for the parameters of the function. Users can view the documentation or edit and execute the source code. Execution can happen either on the local computer, on a remote server, or in the browser (through Pyjamas). Code in one article can be invoked by another article through regular function calls, without any changes to the syntax of the Python language. It also offers a package that imports article code into a local Python namespace for offline development.
Qt for Urbi is a binding of the Qt library in Urbi, enabling you to create native graphical interfaces dynamically directly from Urbi. It exposes urbiscript events to ease the use of Qt signals and slots. Major and minor version numbers of the Qt for Urbi packages reflects the Urbi SDK version number for which they were built. Loading it in another version of the Urbi kernel probably won't work. For instance, Qt for Urbi 2.4.x will only work with Urbi SDK 2.4.y. It is still a bit experimental. Only the 32-bit Linux version is available, and not all classes and members are bound yet.
Charm++ is a portable adaptive runtime system for parallel applications. Application developers create an object-based decomposition of the problem of interest, and the runtime system manages issues of communication, mapping, load balancing, fault tolerance, and more. Sequential code implementing the methods of these parallel objects is written in C++. Calls to libraries in C++, C, and Fortran are common and straightforward. Charm++ is portable across individual workstations, clusters, accelerators (Cell SPEs and GPUs), and supercomputers such as those sold by IBM (Blue Gene, POWER) and Cray (XT3/4/5/6). Applications based on Charm++ are used on at least 5 of the 20 most powerful computers in the world.
