    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.

    Extended C Library

    Extended C Library

    Why Is libxc needed? There doesn't exist a library for ANSI C99 for common data containers, such as vectors, trees, etc. There also also doesn't exist a library for common functionality, such as error reporting/logging, string functions, configuration management (reading config files), etc... The programmer working in C doesn't have anything analogous to the Boost C++ library. The extended C library is intended to make some headway into providing this functionality. To ensure unrestricted usage the libxc project is provided under the very permissive BSD license. If you need a different license then please send me a request (lelanthran at gmail) and I'll do my best to satisfy your request. What's completed? As of writing, the following libraries have been written and tested: 1. Memory accounting/tracking 2. String operations 3. Vectors 4. Trees 5. Dictionary arrays 6. Configuration management See the wiki page for more information

    Ada industrial control widget library

    Ada industrial control widget library

    A GUI library for designing gauges, meters, oscilloscopes, plotters

    A library that is intended for designing high-quality industrial control widgets for Ada applications. The widgets are composed of transparent layers drawn by cairo. The widgets are fully scalable graphics. A time controlled refresh policy is supported for real-time and heavy-duty applications. The library supports caching graphical operations and stream I/O for serialization and deserialization. Ready-to-use gauge, meter, oscilloscope widgets are provided as samples as well as an editor widget for WYSIWYG design of complex dashboards. The software is based on GtkAda and cairoada, the Ada bindings to GTK+ and cairo.

    Unix GNU Windows

    Packages to create a Unix like environment under MS-Windows

    At this point this project is mainly wpkg which is a replica of dpkg and apt-get that works under Microsoft Windows and Unices. Since version 0.7.0 it works very nicely as it includes most of the important functionality of dpkg (i.e. most everything except dselect functions.) Otherwise, the Unix GNU Windows is expected to be a large set of packages that wpkg can handle. Packages of all the software available under MinGW and GnuWin32 so you can painlessly build a complete Unix like environment under Microsoft Windows.

    ALEPH-w

    ALEPH-w

    Data structures and Algorithms library

    Aleph-w is a library of data structures and algorithms implemented in and for C++. It contains the main data structures: single and double lists, special arrays (dynamic and of bits), many types of trees: multitrees, binary search trees, avl, red-black, randomized, treaps, splay and other interesting types. Several types of hash tables are implemented: separated chaining, open adressing with linear probing and double function hash; this last one has a garbage colector mechanism that allows to free deleted entries. Dynamic linear hash tables are implemented too. The main algorithms on graphs are implemented in an easy way and with good performance features. Network Flow (maximum and min cost), cut points, topological sort, spanning trees, min paths. etc. The graphs are generic in the sense that they can contain data independent of the algorithm. Several containers of the C++ STL library are implemented with Aleph-w. Their performance is better than GNU implementation

    Heterogeneous cluster for acceleration of linear algebra computations

    This project deals with a new concept of the heterogeneous grid for acceleration of the numerical linear algebra computing. We design this grid with respect to maximal ratio between cost and computational power. It allows a parallelization of scientific codes with minimal programming effort. We also optimize grid concept to be less sensitive to network parameters.
