SHTns is a high-performance Spherical Harmonic Transform library. It was designed for numerical simulation (fluid flows, mhd, etc.) in spherical geometries, but can be used for any kind of problem involving scalar or vector spherical harmonics. It is very fast, thanks to careful vectorization and runtime tuning. It supports multi-threaded transforms via OpenMP. It features scalar and vector transforms, synthesis and analysis, and flexible truncation and normalization. A Python interface is included.
Userfriendly SVN (USVN) is a Web-based interface to configure your subversion repositories. This interface allows you to create new projects without a command line client, and it requires priviliged access to the server. USVN will take care of managing the list of users which are authorized to check out source code. This allows you to delegate the administration of your Subversion depots. USVN permits easy management of access restriction on Subversion files.
GREYCstoration is an image regularization algorithm that processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners. The most direct application is denoising. By extension, it can also be used to inpaint or resize images. It is based on methods using nonlinear multi-valued diffusion PDEs (Partial Differential Equations) for image regularization. This kind of method generally outperforms basic image filtering techniques (such as convolution, median filtering, etc.) classically encountered in painting programs. Other image denoising plugins are available, but are not free, and the corresponding algorithms are kept secret.
Orfeo Toolbox (OTB) is a high resolution remote sensing image processing library. It contains a set of algorithmic components which allow the user to capitalize on methodological know how, and therefore use an incremental approach to profit from the results of methodological research. OTB is made of a set of basic elements (a C++ class API) and utilities (independent programs built upon the base API).
BitDew is a programmable environment for the management and distribution of data for grid, desktop grid, and cloud systems. It can easily be integrated into large scale computational systems such as XtremWeb, BOINC, Hadoop, Condor, Glite, Unicore, OpenStack, and Eucalyptus. It provides key P2P, grid, and cloud technologies (DHT, BitTorrent, Amazon S3, DropBox) and high level programming interfaces with a simple API for creating, accessing, storing, and moving data with ease, even in highly dynamic and volatile environments.
RefleX is a Java tool that allows people that have no particular knowledge of Java to write smart programs entirely in XML. The concepts of native XML programming used in RefleX have been designed separately, so that other implementations on other platforms/languages can be considered. As the tags used are considered "active", the underlying concepts have been named "Active Tags". Programming in XML allows developers to efficiently produce batch scripts as well as Web applications. With Active Tags, you can dramatically decrease the number of lines you have to code.
V_Sim visualizes atomic structures such as crystals, grain boundaries, molecules, and so on It can work with files either in binary format or in plain text format. The rendering is done in pseudo-3D with colored spheres to represent the atoms. The user can interact through many functions to choose the view, the size of the atoms, their color, the background color, the type of fog, and more. Moreover, V_Sim allows you to export the view as images in GIF, PS, and other formats.
