Nous vous donnons ici la liste des logiciels installés sur la grappe de calcul. Comme indiqué dans cette page , nous vous invitons fortement à utiliser la grappe à partir du frontal tycho en utilisant le système de soumission de jobs. Cela permet de mieux répartir les jobs que vous lancez, ce qui optimise pour tout le monde l'utilisation des ressources de calcul. Nous rappelons qu'il faut faire la compilation sur le frontal à savoir tycho et non sur les noeuds de calcul. Le compilateur NAGWare Fortran n'est disponible que sur la machine nag-server pour une raison de licence et pour les utilisateurs du groupe nag.

Pour l'installation du compilateur INTEL sur votre poste de travail, vous devez télécharger le fichier pour votre type de machine dans http: Les packages externes mscred, ctio, fitsutil, nmisc etc Machine-dependent constants and the timing function may need to be modified by the user when installing the packages for a particular computer. The associated matrix factorizations LU, Cholesky, QR, SVD, Schur, generalized Schur are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers.

Dense and banded matrices are handled, but not general sparse matrices.

In all areas, similar functionality is provided for real and complex matrices, in both single and double precision. For instance, see Atlas. LaTeX is the de facto standard for the communication and publication of scientific documents.

It is platform- and format-independent and works together with the most important TeX backend drivers, including pdftex and dvips. It comes with a user-friedly syntax layer called TikZ. By default, LaTeX will number equations consecutively, as 1 , 2 , etc. If the paper is very short, or if there are only a few numbered equations, this is fine, but once the numbers get into the twenties and higher, a scheme that numbers equations by section, as in 1.

In fact, for the vast majority of journal articles, the latter is probably the best numbering scheme. To get equations numbered by section, just put the following into the preamble: For books, theses, or very long papers, an equation numbering scheme that is three levels deep with numbers like 4.

The same mechanism works for other counters, e. On machines where the epstopdf external command is not available to LaTeX, one can also convert eps figures to pdf with:.

Development began in March with the intent of providing a friendly interface to a number of high-quality software packages that are currently available.

Currently the library supports 2D and 3D steady and transient finite element simulations. PETSc is currently used for the solution of linear systems on both serial and parallel platforms, and LASPack is included with the library to provide linear solver support on serial machines. Many thanks to SourceForge for hosting the project.

You can find out what is currently happening in the development branch by checking out the CVS Logs online. A major goal of the library is to provide support for adaptive mesh refinement AMR computations in parallel while allowing a research scientist to focus on the physics they are modeling.

Libtool hides the complexity of using shared libraries behind a consistent, portable interface. To use libtool, add the new generic library building commands to your Makefile, Makefile. See the documentation for details. Et une autre liste en anglais: Alain Perronnet http: Il a été développé par D.

Matlab utilise par défaut tous les coeurs disponibles. Il faut donc ajouter -singleCompThread dans le fichier. Par exemple:. Ceci est très utile en conjonction avec nohup ou screen. Voici aussi un exemple de script qsub:.

Quelques exemples avec les temps de calcul associés: Si on définit la fonction suivante dans le fichier leg. I do not describe the commercial Matlab software here but its file formats, because these are understood by many other programs. They can be created on one machine and later read by MATLAB on another machine with a different floating-point format, retaining as much accuracy and range as the different formats allow.

In particular, the objective has been to define a minimal base ASCII file format which can be very easily explained and parsed, but can easily adapted to applications with a more rigid structure, or extended to related data objects. The MM exchange format for matrices is really a collection of affiliated formats which share design elements.

In our initial specification, two matrix formats are defined. Maxima produces high precision results by using exact fractions and arbitrarily long floating point representations, and can plot functions and data in two and three dimensions.

The source code for all systems and precompiled binaries for Windows and Linux are available at the SourceForge file manager. Maxima is a descendant of Macsyma, the legendary computer algebra system developed in the late s at the Massachusetts Institute of Technology. It is the only system based on that effort still publicly available and with an active user community, thanks to its open source nature.

Macsyma was revolutionary in its day, and many later systems, such as Maple and Mathematica, were inspired by it. It provides a GUI written using Tkinter. MayaVi is free and distributed under the conditions of the BSD license. The underlying algorithms used by METIS are based on the state-of-the-art multilevel paradigm that has been shown to produce high quality results and scale to very large problems.

It may be used to solve linear systems, to estimate the condition number or the norm of a matrix, to compute determinants, to multiply a matrix by a vector, to invert a matrix, to solve least squares problems, to perform unconstrained minimization, to compute eigenvalues, eigenvectors, the singular value decomposition, or the QR decomposition. The package has special routines for general, band, symmetric, indefinite, tridiagonal, upper Hessenberg, and circulant matrices. The operators are primarily designed to aid manipulation and analysis of gridded scientific data.

The single command style of NCO allows users to manipulate and analyze files interactively and with simple scripts, avoiding the overhead and some of the power of a higher level programming environment. The operators are as general as NetCDF itself: The internal routines of NCO are completely dynamic which means that NCO imposes no limit on the number of dimensions, sizes of variables, files etc.

NCO is designed to be used both interactively and with large batch jobs. There are plenty of command line i. Netgen is open source based on the LGPL license. Version 1. NGSolve performs adaptive mesh refinement, the matrix equations are solved by optimal order multigrid methods.

Older libraries corresponding to previous designs are also included for archival and historical purposes. Les calculs lancés en tâche de fond ne peuvent pas être stoppés avec Control-C. Il faut utiliser les commandes kill ou killall. Pour interrompre un calcul précis, il faut connaître son identifiant numéro compris entre 1 et , avec la commande:. Pour résoudre la partie Euler des equations, le flux de Roe, de Osher et un flux cinetique sont disponibles. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.

It may also be used as a batch-oriented language. Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. Its main features are: The package contains in addition: It supports ASCII text versions of objects for the purpose of interchange, and binary versions for efficiency of reading and writing.

The aim of this project is to develop efficient and robust tool for FEM computations as well as to provide modular and extensible environment for future development. The license allows you to freely create, distribute, and develop visualization solutions as you see fit. OpenDX is a uniquely powerful, full-featured software package for the visualization of scientific, engineering and analytical data: Its open system design is built on a standard interface environments.

And its sophisticated data model provides users with great flexibility in creating visualizations. With OpenDX, you can create the visualizations you want to create.

OpenDX has been designed to be the place where the art of science and the science of visualization come together. It has advanced joint types and integrated collision detection with friction.

ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools. It is available for both Matlab and Scilab. External contributions are strongly encouraged for the forthcoming versions in order to enlarge and improve the toolbox. These are used to build a wealth of: OpenFOAM is supplied with numerous pre-configured solvers, utilities and libraries and so can be used like any typical simulation package.

However, it is open, not only in terms of source code, but also in its structure and hierarchical design, so that its solvers, utilities and libraries are fully extensible. The fluid flow solvers are developed within a robust, implicit, pressure-velocity, iterative solution framework, although alternative techniques are applied to other continuum mechanics solvers. The goals of the ParaView project include the following: ParaView runs on distributed and shared memory parallel as well as single processor systems and has been succesfully tested on Windows, Linux and various Unix workstations and clusters.

See also http: PARI is also available as a C library to allow for faster computations. It is based on a preconditioned Krylov subspace approach, using a domain decomposition viewpoint. It offers a large selection of preconditioners for distributed sparse linear systems and a few of the best known accelerators. The basic methodology used relies on a Recursive Multi-level ILU factorization wich allows to develop many of the standard domain-decomposition type iterative solvers in a single framework.

For example, the standard Schwarz procedures are included as are a number of Schur complement techniques. Il existe une version pour Windows. Opérateurs de test sur les fichiers: Voici par exemple un fichier dont le nom contient une valeur de vitesse.

PETSc includes nonlinear and linear equation solvers that employ a variety of Newton techniques and Krylov subspace methods. PETSc provides several parallel sparse matrix formats, including compressed row, block compressed row, and block diagonal storage. To make this task manageable in the arena of linear algebra algorithms, we have developed the Parallel Linear Algebra Package PLAPACK , an infrastructure for coding such algorithms at a high level of abstraction.

It is often believed that by raising the level of abstraction in this fashion, performance is sacrificed. Throughout, we have maintained that indeed there is a performance penalty, but that by coding at a higher level of abstraction, more sophisticated algorithms can be implemented, which allows high levels of performance to be regained.

In this paper, we show this to indeed be the case for the parallel solver package implemented using PLAPACK, which includes Cholesky, LU, and QR factorization based solvers for symmetric positive definite, general, and overdetermined systems of equations, respectively.

Each plot comes with a simple but functional Graphical User Interface which allows users to zoom in or pan to areas of interest on the plot or to toggle between 2D and 3D plots. Tutorial at http: POOMA has been optimized to take full advantage of massively parallel machines. POOMA is available free of charge in order to facilitate its use in both industrial and research environments.

The source code is available for those wanting to do their own ports. Hightlights and Performance ,. These implementations differed substantially from each other making it difficult for programmers to develop portable threaded applications. Pthreads are defined as a set of C language programming types and procedure calls, implemented with a pthread. It is important to be aware of the draft number of a given implementation, because there are differences between drafts that can cause problems.

Voir aussi http: Par défault, un script est exécuté dans un répertoire temporaire différent du répertoire où il a été soumis. Pour changer ce comportement, ajouter au début du script:. Les fuites de mémoires arrivent le plus souvent quand tous les malloc ne sont pas suivis par un free. On linux-type systems, use nm. T shows defined symbols, U shows undefined ones. The source for the program is needed.

First try to locate where this error appears. This is done by adding -g when compiling and running the code through gdb.

If there is no programming error at the location where the error occurs, it can be the consequence of an earlier error memory errors may not be detected immediately. If this is the case then valgrind may be able to detect where the first error occurred:. Les fichiers maillage. Voici un exemple où le fichier à traduire contient un vecteur: Pour cela il suffit de configurer le domaine 2D comme une bande rectangulaire dont les côtés obéissent à une condition aux limites périodique.

For more information on how to specify a periodic boundary condition, see the fespace keyword. La matrice élémentaire peut ensuite être obtenue en appliquant le problème global au petit maillage. Pour une échelle verte, remplacer la première coordonnée de chaque couleur hue par 0.

Elle est imposée sur le terme diagonal de la matrice ce qui rend les autres termes de la même ligne négligeables et au second membre. Un désavantage est de créer une très grande valeur propre dans le système à résoudre, ce qui peut mettre en difficulté la méthode de résolution choisie. Voici un script perl qui sait traduire les SVG qui contiennent des courbes de Bézier cubiques et des lignes droites:.

Le mot-clé problem ne permet pas de manipuler les matrices. Il faut utiliser le mot-clé varf avec les précautions suivantes:. Voici comment augmenter la petite dimension du domaine juste pour afficher les valeurs numériques de manière visible.

Cet exemple peut facilement être transformé pour lire tout autre format de maillage 2D enregistré dans un fichier texte:. Returning a vector as the value of a function may sometimes pose problems. If the case arises, just tranform the return value into a function parameter. Voir aussi How to copy a sparse matrix into a dense matrix? Chubar, P. Elleaume, J. This environment is currently under development. RLaB is an interactive, interpreted scientific programming environment.

RLaB is a very high level language intended to provide fast prototyping and program development, as well as easy data-visualization, and processing. RLaB does not try to be a Matlab clone. Instead, it borrows what I believe are the best features of the Matlab language and provides improved language syntax and semantics.

The syntax has been improved to allow users more expression and reduce ambiguities. The variable scoping rules have been improved to facilitate creation of larger programs and program libraries. A heterogeneous associative array has been added to allow users to create and operate on arbitrary data structures.

The fundamental data type is a floating point matrix either real or complex , though RLaB also includes string matrices, and sparse numerical matrices both real and complex.

Project rlabplus is a continuation of work on an open-source scripting environment for scientific computations RLaB2. Project rlabplus provides release 2 of RLaB2, which contains upgrades of the numerical libraries used in the first release, and many new libraries and toolkits, e. Rlabplus is a creation of Marijan Kostrun. It combines the power of many existing open-source packages into a common Python -based interface.

Creating a viable free open source alternative to Magma, Maple, Mathematica and Matlab. It is based on an open and flexible architecture made of reusable components available as free software. It is open-source LGPL , and you can download both the sourcecode and the executables from this site. Format de données standard lus: Format de données standard écrits: Une version pour Windows version de test, pas la plus récente mais fonctionnelle est téléchargeable à http: It is currently written in a Single-Program-Multiple-Data style using explicit message passing for interprocessor communication.

It assumes matrices are laid out in a two-dimensional block cyclic decomposition. For such machines, the memory hierarchy includes the off-processor memory of other processors, in addition to the hierarchy of registers, cache, and local memory on each processor. Distributed freely via the Internet since , Scilab is currently being used in educational and industrial environnments around the world. Scilab includes hundreds of mathematical functions with the possibility to add interactively programs from various languages C , Fortran ….

It has sophisticated data structures including lists, polynomials, rational functions, linear systems… , an interpreter and a high level programming language. Scilab has been conceived to be an open system where the user can define new data types and operations on these data types by using overloading.


Control-A d. It can be used for the solution of problems formulated in either standard or generalized form, as well as other related problems such as the singular value decomposition. The emphasis of the software is on methods and techniques appropriate for problems in which the associated matrices are sparse, for example, those arising after the discretization of partial differential equations.

Therefore, most of the methods offered by the library are projection methods or other methods with similar properties. Examples of these methods are Arnoldi, Lanczos and Subspace Iteration, to name a few.

SLEPc implements these basic methods as well as more sophisticated algorithms. It also provides built-in support for spectral transformations such as the shift-and-invert technique. SLEPc is a general library in the sense that it covers standard and generalized eigenvalue problems, both Hermitian and non-Hermitian, with either real or complex arithmetic.

It can be considered an extension of PETSc providing all the functionality necessary for the solution of eigenvalue problems. It is a package of scientific software and graphical user interfaces for use in computational fluid dynamics. It is a package of scientific software and graphical user interfaces for use in finite element analysis. Besides being able to solve linear systems, it solves transposed systems, finds determinants, and estimates errors due to ill-conditioning in the system of equations and instability in the computations.

SPARSE does not require symmetry and is able to perform numerical pivoting either diagonal or complete to avoid unnecessary error in the solution.

It was originally written for use in circuit simulators and is particularly apt at handling node- and modified-node admittance matrices. The software package consists of matrix classes encompassing several sparse storage formats e. Included in the package are various preconditioners commonly used in iterative solvers for linear systems of equations.

At present, there is the following functionality: It is a list of the triangular surfaces that describe a computer generated solid model. This is the standard input for most rapid prototyping machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices.

The matrix columns may be preordered before factorization either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization.

Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.
