De grundlæggende funktioner i Code_Saturne gør det muligt at håndtere inkompressible eller kompressible strømme med eller uden varmeoverførsel og turbulens. Dedikerede moduler er tilgængelige for specifik fysik såsom strålingsvarmeoverførsel, forbrænding (gas, kul, svær brændselsolie ...), magneto-hydrodynamik, kompressible strømme, to-fase-strømme (Euler-Lagrange-tilgang med gensidig kobling), udvidelser til specifikke anvendelser (f.eks. Mercure_Saturne for atmosfærisk miljø).

Programmet kører parallelt med MPI på maskiner med distribueret hukommelse. Det har været i udvikling siden 1997 på EDF F&U og er baseret på en co-beliggende Finite Volume-tilgang, der accepterer masker med enhver form for celle (tetraederformet, hexahedral, prismatisk, pyramideformet, polyhedral ...) og enhver form for gitterstruktur (ustruktureret, blokstruktureret, hybrid, overensstemmende eller med hængende knudepunkter ...).

Denne pakke indeholder de binære filer.

GAP er et system til computerstyret diskret algebra med særlig vægt på computerstyret gruppeteori. GAP tilbyder et programmeringssprog, et bibliotek med tusinder af funktioner, der implementerer algebraiske algoritmer skrevet i GAP-sproget samt store databiblioteker med algebraiske objekter. GAP bruges indenfor videnskab og undervisning til studering af grupper og deres repræsentation, ringe, vektorrum, algebraer, kombinatoriske strukturer med mere.

Denne pakke indeholder GAP-kompileren og teksthovedfilerne og objektfiler nødvendige for at bygge GAP-pakker.

GAP-kompileren (GAC) opretter C-kode fra GAP-kode og kalder så systemets C-kompiler for at fremstille maskinkode. Dette kan medføre en hastighedsforøgelse.

JEL-biblioteket gør det muligt for brugere at indtaste algebraiske udtryk i deres program. Da JEL konverterer udtryk direkte til Javabytecode, så øges hastigheden signifikant for evalueringstiden. Hvis brugerens virtuelle maskine for Java har en JIT-kompiler, så kompileres udtryk gennemsigtigt til maskinkode.

JEL kan være et meget nyttig værktøj for en række af programmer indenfor videnskab, der involverer brugerdefinerede funktioner, f.eks. oprettelsen af plot, anvende tilpasninger på datasæt og til at løse integraler eller differentialligninger. En anden relevant brug af JEL er for algebraiske operationer mellem to eller flere kolonner i en databasetabel.

ANN er et bibliotek skrevet i C++, der understøtter datastrukturer og algoritmer for både eksakt og tilnærmelsesvis nabosøgning i vilkårligt høje dimensioner. ANN antager at afstande måles med enhver klasse fra afstandsfunktionerne kaldet Minkowski-metrikker. Disse inkluderer de velkendte euklidiske afstande, Manhattan-afstand og maksimal afstand. ANN yder ganske effektivt for punktsæt i størrelsesintervallet fra tusinder til hundrede af tusinder, og i så højt som 20 dimensioner.

Denne pakke indeholder teksthovedfilerne for udvikling af programmer med ANN-biblioteket.

ARPACK-programmet er i stand til at løse symmetriske, asymmetriske og generaliserede egenværdiproblemer i stor skala inden for mange anvendelser. Programmet er designet til at beregne nogle få (k) egenværdier med brugerangivne funktioner såsom dem med størst real del eller størst størrelsesorden. Lagerkrav er i absolutværdi n*k elementer. Intet ekstra lager er krævet. Et sæt Schur-basisvektorer for det ønskede k-dimensionale egenrum beregnes, hvilket er numerisk ortogonalt ned til arbejdspræcision. Numerisk præcise egenvektorer er tilgængelige efter forespørgsel.

Denne pakke indeholder de statiske biblioteker og dokumentationen for udvikling med libarpack (inklusive eksempler).

Denne pakke er en binær inkompatibel opgradering til pakken blas-dev. Flere mindre ændringer til C-grænsefladen er blevet indarbejdet.

BLAS (Basic Linear Algebra Subroutines) er et sæt af effektive rutiner, til de fleste grundlæggende vektor- og matricehandlinger. De anvendes i udbredt grad som grundlaget for andet højkvalitets- programmel for lineær algebra, eksempelvis lapack og linpack. Denne implementering er Fortran 77 reference-implementeringen, der findes i netlib.

Denne pakke indeholder en statisk version af biblioteket.

BLIS is a portable software framework for instantiating high-performance BLAS-like dense linear algebra libraries. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations. BLIS is written in ISO C99 and available under a new/modified/3-clause BSD license. While BLIS exports a new BLAS-like API, it also includes a BLAS compatibility layer which gives application developers access to BLIS implementations via traditional BLAS routine calls. An object-based API is also available for more experienced users.

The package pulls development files for one of the 32-bit BlasInt variants.

Minpack includes software for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix or directly from the problem functions. The paths include facilities for systems of equations with a banded Jacobian matrix, for least squares problems with a large amount of data, and for checking the consistency of the Jacobian matrix with the functions.

This is the C re-write of the original fortran minpack implementation.

This package contains development files needed to build cminpack applications.

Neartree is an API and a library for finding nearest neighbors among points in spaces of arbitrary dimensions. This package provides a C++ template, TNear.h, and C library and header files for compiling programs using Neartree.

The library uses the Nearest Neighbor algorithm after Kalantari and McDonald, (IEEE Transactions on Software Engineering, v. SE-9, pp. 631-634,1983) modified to use recursion instead of a double-linked tree and simplified so that it does less checking for things like is the distance to the right less than the distance to the left; it was found that these checks make little to no difference.

The Combinatorial BLAS (CombBLAS) is an extensible distributed-memory parallel graph library offering a small but powerful set of linear algebra primitives specifically targeting graph analytics.

  • The Combinatorial BLAS development influences the Graph BLAS standardization process.
  • It achieves scalability via its two dimensional distribution and coarse-grained parallelism.
  • CombBLAS powers HipMCL, a highly-scalable parallel implementation of the Markov Cluster Algorithm (MCL).
  • Operations among sparse matrices and vectors use arbitrary user defined semirings.

This package provides development files for building client applications against combblas.

The Fast Library for Integer Number Theory is a C library which supports polynomial arithmetic over the integers, fast integer arithmetic and factoring (including a highly optimized quadratic sieve).

FLINT has functionality similar to that of the Number Theory Library (NTL). However, unlike NTL, which is designed primarily for asymptotic performance, FLINT is designed for good performance in small cases as well.

This package contains the FLINT development files.

FreeFem++ er en implementering af et sprog dedikeret til den finitte elementmetode. Du kan dermed nemt løse Partial Differential Equations (PDE).

Problemer der involverer PDE fra specielle grene af fysikken såsom LUID-strukturinteraktioner kræver interpolationer af data på flere masker og deres manipulation inden i et program. FreeFe ++ inkluderer en hurtig quadtree-baseret interpolationsalgoritme og et sprog til manipulation af disse oplysninger på flere masker. Det indeholder også en stærk mesh-oprettelse og et tilpasningsværktøj integreret problemfrit i FreeFem++ kaldet bamg.

FreeFem++ er skrevet i C++ og sproget FreeFem++ er et C++-idiom, der giver en blød indlæringskurve.

Denne pakke indeholder udviklingsfilerne for FreeFem++.

This is not a full linear algebra library, only a GEMM library: it only does general matrix multiplication ("GEMM").

Its performance goals differ from typical GEMM performance goals in the following ways: 1. It cares not only about speed, but also about minimizing power usage.

   It specifically cares about charge usage in mobile/embedded devices.
2. Most GEMMs are optimized primarily for large dense matrix sizes (>= 1000).
   It does care about large sizes, but it also cares specifically about the
   typically smaller matrix sizes encountered in various mobile applications.

Keep in mind (previous section) that gemmlowp itself is a pure-headers-only library.

This interface allows gnuplot to be controlled from C++ and is designed to be the lowest hanging fruit. In other words, if you know how gnuplot works it should only take 30 seconds to learn this library. Basically it is just an iostream pipe to gnuplot with some extra functions for pushing data arrays and getting mouse clicks. Data sources include STL containers (eg. vector or map) and one or two dimensional Blitz++ arrays (of scalars or TinyVectors). Support for other data sources should be easy to add.

Basically there are two functions defined: send() sends arrays of data values (it is overloaded to do the right thing based upon what type of variable you pass) and getMouse() gets the position of a mouse click. Everything else is accomplished by sending commands manually to gnuplot via the iostream interface.

IML is a library for exact, dense linear algebra over the integers. IML contains algorithms for nonsingular rational system solving, computing the right nullspace of an integer matrix, and certified linear system solving.

In addition, IML provides some low level routines for a variety of mod p matrix operations: computing the row-echelon form, determinant, rank profile, and inverse of a mod p matrix. These mod p routines are not general purpose; they require that p satisfy some preconditions based on the dimension of the input matrix (usually p should be prime and should be no more than about 20 bits long).

This package contains development files for IML.

ITSOL is a library of iterative solvers for general sparse linear systems of equations. ITSOL can be viewed as an extension of the itsol module in SPARSKIT. It is written in C and offers a selection of recently developed preconditioners. The preconditioner suite includes:

  • ILUK (ILU preconditioner with level of fill)
  • ILUT (ILU preconditioner with threshold)
  • ILUC (Crout version of ILUT)
  • VBILUK (variable block preconditioner with level of fill - with automatic block detection)
  • VBILUT (variable block preconditioner with threshold - with automatic block detection)
  • ARMS (Algebraic Recursive Multilevel Solvers -- includes actually several methods - In particular the standard ARMS and the ddPQ version which uses nonsymmetric permutations)

Note that ITSOL is a scalar package. You may find parallel implementations of some of the preconditioners listed above in pARMS.

This package provides the itsol header files required to compile C/C++ programs that use ITSOL.

JAMA/C++ was adapted for The Template Numerical Toolkit (TNT) from JAMA, a Java Matrix Library, developed jointly by the Mathworks and NIST. See http://math.nist.gov/javanumerics/jama for more information.

TNT is a collection of interfaces and reference implementations of numerical objects useful for scientific computing in C++. The toolkit defines interfaces for basic data structures, such as multidimensional arrays and sparse matrices, commonly used in numerical applications. The goal of this package is to provide reusable software components that address many of the portability and maintenance problems with C++ codes.

TNT provides a distinction between interfaces and implementations of TNT components. For example, there is a TNT interface for two-dimensional arrays which describes how individual elements are accessed and how certain information, such as the array dimensions, can be used in algorithms; however, there can be several implementations of such an interface: one that uses expression templates, or one that uses BLAS kernels, or another that is instrumented to provide debugging information. By specifying only the interface, applications codes may utilize such algorithms, while giving library developers the greatest flexibility in employing optimization or portability strategies.

Solves nonlinear optimization problems using the limited-memory BFGS method. The user specifies a callback C function that returns the value and gradients of the cost function at a particular operating point. This library estimates the Hessians from user input, and applies Newton's method iteratively to find a local minimum of the cost function. This is a small library, written in C with minimal dependencies.

This package implements the Leiden algorithm in C++. It relies on igraph for it to function. Besides the relative flexibility of the implementation, it also scales well, and can be run on graphs of millions of nodes (as long as they can fit in memory). The core class is Optimiser which finds the optimal partition using the Leiden algorithm, which is an extension of the Louvain algorithm for a number of different methods. The methods currently implemented are (1) modularity, (2) Reichardt and Bornholdt's model using the configuration null model and the Erdös-Rényi null model, (3) the Constant Potts model (CPM), (4) Significance, and finally (5) Surprise. In addition, it supports multiplex partition optimisation allowing community detection on for example negative links or multiple time slices. There is the possibility of only partially optimising a partition, so that some community assignments remain fixed. It also provides some support for community detection on bipartite graphs.

This package contains the C++ development files. Most people will find it easier to work with the Python interface provided by python3-leidenalg.

Lip interpolates scattered multivariate data with a Lipschitz function.

Methods of interpolation of multivariate scattered data are scarce. The programming library Lip implements a new method by G. Beliakov, which relies on building reliable lower and upper approximations of Lipschitz functions. If we assume that the function that we want to interpolate is Lipschitz-continuous, we can provide tight bounds on its values at any point, in the worse case scenario. Thus we obtain the interpolant, which approximates the unknown Lipschitz function f best in the worst case scenario. This translates into reliable learning of f, something that other methods cannot do (the error of approximation of most other methods can be infinitely large, depending on what f generated the data).

Lipschitz condition implies that the rate of change of the function is bounded:

|f(x)-f(y)|<M||x-y||.

It is easily interpreted as the largest slope of the function f. f needs not be differentiable.

The interpolant based on the Lipschitz properties of the function is piecewise linear, it possesses many useful properties, and it is shown that it is the best possible approximation to f in the worst case scenario. The value of the interpolant depends on the data points in the immediate neigbourhood of the point in question, and in this sense, the method is similar to the natural neighbour interpolation.

There are two methods of construction and evaluation of the interpolant. The explicit method processes all data points to find the neighbours of the point in question. It does not require any preprocessing, but the evaluation of the interpolant has linear complexity O(K) in terms of the number of data.

"Fast" method requires substantial preprocessing in the case of more than 3-4 variables, but then it provides O(log K) evaluation time, and thus is suitable for very large data sets (K of order of 500000) and modest dimension (n=1-4). For larger dimension, explicit method becomes practically more efficient. The class library Lip implements both fast and explicit methods.

M4RI is a library for fast arithmetic with dense matrices over F2. The name M4RI comes from the first implemented algorithm: The "Method of the Four Russians" inversion algorithm. This algorithm in turn is named after the "Method of the Four Russians" multiplication algorithm which is probably better referred to as Kronrod's method.

This package contains development files for libm4ri.

M4RIE is a library for fast arithmetic with dense matrices over small finite fields of even characteristic. It uses the M4RI library, implementing the same operations over the finite field F2.

The name M4RI comes from the first implemented algorithm: The "Method of the Four Russians" inversion algorithm. This algorithm in turn is named after the "Method of the Four Russians" multiplication algorithm which is probably better referred to as Kronrod's method.

This package contains development files for the M4RIE library.

Denne pakke indeholder udviklingsfilerne (teksthover, so og statiske biblioteker) for MAdLib.

MAdLib er et bibliotek, der udfører global knude-repositionering og mesh-tilpasning ved lokale mesh-ændringer på tetraedriske eller trekantede mesh'er. Den er designet til ofte at tilpasse mesh'en i forbigående beregninger. MAdLib er skrevet i C++.

Tilpasningsproceduren er drevet af to mål:

  • gør kantlængderne så tætte som mulige på en (ikkehomogen)

    foreskrevet længde

  • opretholde en tilfredsstillende elementkvalitet overalt.

MAdLib kan bruges i forbigående beregninger for at opretholde en tilfredsstillende elementkvalitet (flytning af grænser, flerfasestrømme med grænsefladesporing ...) eller/og at anvende selektive justeringer og forgrovninger (baseret på fejlestimeringer, grænsefladeregistrering: stød, frie overflader ...).

Denne pakke tilbyder et C-bibliotek med funktioner for intervalberegninger indenfor aritmetik med arbitrær præcision.

Det grundlæggende princip med intervalaritmetik består i at omslutte hvert tal med et interval indeholdende tallet og værende repræsenteret af maskintal: for eksempel kan det lagres som sit nedre og øvre slutpunkter og disse grænser er maskintal, eller som et centrum og en radius, der er maskintal.

De aritmetiske operationer udvides for intervaloperander på en sådan måde, at det præcise resultat for operationen tilhører det beregnet interval.

Formålet med en intervalaritmetik med arbitrær præcision er på den ene side at få garanterede resultater, takker være intervalberegning, og på den anden side at få præcise resultater, takket være præcisionsaritmetik. Biblioteket MPFI er bygget på MPFR for at få fordel af de korrekte afrundinger tilbudt af MPFR. Andre fordele ved at bruge MPFR er dets evne til at kunne flyttes og overholdelse af IEEE 754-standarden for kommatals aritmetik.

Denne pakke tilbyder det statiske bibliotek og symbolske henvisninger krævet for udvikling.

OpenMesh is a generic and efficient data structure for representing and manipulating polygonal meshes. It was designed with the following goals in mind:

  • Flexibility: provide a basis for many different algorithms without the need for adaptation.

  • Efficiency: maximize time efficiency while keeping memory usage as low as possible.

  • Ease of use: wrap complex internal structure in an easy-to-use interface.

OpenMesh provides the following features:

  • Representation of arbitrary polygonal (the general case) and pure triangle meshes (providing more efficient, specialized algorithms)

  • Explicit representation of vertices, halfedges, edges and faces.

  • Fast neighborhood access, especially the one-ring neighborhood

  • Highly customizable

  • Choose your coordinate type (dimension and scalar type)

  • Attach user-defined elements/functions to the mesh elements.
  • Attach and check for attributes
  • Attach data at runtime using dynamic properties.

This package provides the development files library

QUADRULE is a C library which sets up a variety of quadrature rules, used to approximate the integral of a function over various domains.

QUADRULE returns the abscissas and weights for a variety of one dimensional quadrature rules for approximating the integral of a function. The best rule is generally Gauss-Legendre quadrature, but other rules offer special features, including the ability to handle certain weight functions, to approximate an integral on an infinite integration region, or to estimate the approximation error.

This package provides everything needed for compiling C programs that call quadrule functions.

RanLip opretter vilkårlige variater fra en arbitrær flervariate Lipschitz- tæthed.

Mens oprettelse af vilkårlige tal fra en række distributioner er implementeret i mange pakker (såsom GSL library http://www.gnu.org/software/gsl/ og UNURAN library http://statistik.wu-wien.ac.at/unuran/), så er oprettelsen af vilkårlige variate med en arbitrær distribution, specielt i tilfældet med flervariate en meget udfordrende opgave. RanLip er en oprettelsesmetode for vilkårlige variater med arbitrær Lipschitz-fortsættende tætheder, som virker i de univariate og flervariate tilfælde, hvis dimensionen ikke er meget stor (lad os sige 3-10 variabler).

Lipschitz-betingelsen implicerer at ændringshastigheden for funktionen (i dette tilfælde, tæthedens sandsynlighed p(x)) er bundet:

|p(x)-p(y)|<M||x-y||.

Fra denne betingelse kan vi etablere et overordnet estimat for tætheden, den såkaldte hatte-funktion h(x)>=p(x), med brug af talværdier fra p(x) på enkelte punkter. Jo flere værdier vi anvender, des bedre bliver hatte- funktionen. Metoden til godkendelse/afvisning fungerer dernæst således: opret en tilfældig variat X med tætheden h(x); opret en uafhængig uniform på (0,1) det tilfældige tal Z; hvis p(x)<=Z h(X), så returnér X, hvis ikke så gentag alle ovenstående trin.

RanLip konstruerer en stykvis konstant hat-funktion for den krævede tæthed p(x) ved at underopdele domænet for p (en n-dimensionel rektangel) i mange mindre rektangler, og beregner den øvre grænse på p(x) indenfor hver af disse rektangler, og bruger denne øvre grænse som værdien for hat- funktionen.

Filer tilbudt af denne pakke er krævet for at udvikle nye programmer med biblioteket Scythe. Det er ikke et binært bibliotek forbundet med disse teksthoveder, det vil sige at alle skabelonkoder er indeholdt og ingen yderligere afhængigheder er krævet ved kørselstid.

Scythes statistiske bibliotek er et open source C++-bibliotek for statistisk beregning. Det inkluderer en programpakke af matriksberegningsfunktioner, en programpakke af pseudo-vilkårlige taloprettelser og en programpakke af numeriske optimeringer. Programmer skrevet med brug af Scythe er generelt meget hurtigere end programmer skrevet i almindeligvis brugte fortolkede sprog, såsom R, Matlab og GAUSS; kan kompileres på alle systemer med en GNU GCC compiler (og måske med andre C++-compilere). Et af de primære designmål for Scytheudviklerne har været at gøre brugen nem for programmører, som ikke er eksperter i C++. Nem brug tilbydes via tre primære mekanismer: (1) operatør og funktionsoverindlæsning, (2) adskillelige præfabrikerede redskabsfunktioner og (3) præcis dokumentation og eksempelprogrammer. Yderligere er Scythe meget fleksibel og kan udvides på alle områder, da kildekoden er tilgængelig for alle brugere.

SPARSKIT a basic tool-kit for sparse matrix computations. Sparskit is a general purpose FORTRAN-77 library for sparse matrix computations. It has been gathered over several years and includes some of the most useful tools for developing and implementing sparse matrix techniques, particularly for iterative solvers. If you need a simple routine for doing a sparse matrix operation (e.g., adding two sparse matrices, or reordering a sparse matrix) it is likely to be available in SPARSKIT. SPARSKIT also contains most of the iterative accelerators and a number of efficient preconditioners.

SpFFT was originally intended for transforms of data with spherical cutoff in frequency domain, as required by some computational material science codes. For distributed computations, SpFFT uses a slab decomposition in space domain and pencil decomposition in frequency domain (all sparse data within a pencil must be on one rank). If desired, the library can be compiled without any parallelization (MPI, OpenMP, CUDA / ROCm).

This package contains development files.

STochastic OPTimization library (StOpt) forsøger at tilbyde værktøjer i C++ for løsning af nogle stokastiske optimeringsproblemer mødt i finans eller i industri. Forskellige metoder er tilgængelige:

  • dynamiske programmeringsmetoder baseret på Monte Carlo med regressioner (global, lokal, kerne og rumlig regressor), for underliggende tilstande der følger nogle ukontrollerede stokastiske differentialligninger
  • dynamisk programmering med en repræsentation af usikkerheder med et træ: overgangsproblemer løses her af nogle diskretiseringer af kommandoerne, opløsning af LP med klip-repræsentation af Bellmann- værdierne
  • Semi-Lagrangian-metoder for Hamilton Jacobi Bellman-generelle ligninger for underliggende tilstande, der følger nogle kontrollerede stokastiske differentialligninger
  • Stochastic Dual Dynamic Programming-metoder til at håndtere stokastiske lagerhåndteringsmetoder i høj dimension. Usikkerheder kan angives af Monte Carlo og kan repræsenteres af en tilstand med et finitte antal værdier (træ)
  • Nogle indlejringsmetoder for forgreninger til at løse meget høje dimensionelle og ikkelineære PDE'er og nogle der fremgår af HJK- problemer. Derudover tilbydes nogle metoder til at bruge Monte Carlo til at løse nogle problemer hvor den underliggende stokastiske tilstand er kontrolleret. For hver metode tilbydes en ramme for at optimere problemet og så simulere det ud fra prøven via de optimale kommandoer tidligere beregnet. Paralleliseringsmetoder baseret på OpenMP og MPI tilbydes i denne ramme hvilket gør løsning af høj dimensionelle problemer på klynger mulig. Biblioteket bør være fleksibelt nok til at blive brugt på forskellige niveauer afhængig af brugerens indsats.

Denne pakke indeholder teksthovederne og de statiske biblioteker (libstopt-mpi der gør brug af flere samtidige tråde mulig og libstopt der ikke gør).

Udviklingsfiler for SuperLU.

SuperLU er et alment bibliotek for direkte løsning af store, sparse (tynde), ikkesymmetriske systemer med lineære ligninger på højtydende maskiner.

Biblioteket er skrevet i C og kan kaldes fra enten C eller Fortran. Biblioteksrutinerne vil udføre en LU-dekomposition med delvis pivotoprettelse og triangulær systemløsninger via fremadrettet og bagudrettet substitution. LU-faktoriseringsrutinerne kan håndtere ikkefirkantede matricer men de triangulære løsere udføres kun for firkantmatricer. Matrixkolonnerne kan forudbestilles (før faktorering) enten via biblioteks- eller brugerangivne rutiner. Denne forhåndsordning for sparsity (tynd) er fuldstændig adskilt fra faktoriseringen. Arbejdspræcisions iterative raffinementunderrutiner tilbydes for forbedret baglæns stabilitet. Rutiner tilbydes også til få systemet i ligevægt, estimere betingelsesantallet, beregne den relative tilbagerettet fejlbackward og estimere fejlgrænser for de raffinerede løsninger.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations. The library is written in C and is callable from either C or Fortran program. It uses MPI, OpenMP and CUDA to support various forms of parallelism. It supports both real and complex datatypes, both single and double precision, and 64-bit integer indexing. The library routines performs 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.

SuperLU_DIST implements the algorithms for distributed memory, targetting highly parallel distributed memory hybrid systems. The numerical factorization routines are already implemented for hybrid systems with multiple GPUs. Further work will be needed to implement the other phases of the algorithms on the hybrid systems and to enhance strong scaling to extreme scale.

The main library is libsuperlu_dist.so but a fortran wrapper library is also provided as libsuperlu_dist_fortran.so

This package provides development files for building client applications against superlu-dist.

The Template Numerical Toolkit (TNT) is a collection of interfaces and reference implementations of numerical objects useful for scientific computing in C++. The toolkit defines interfaces for basic data structures, such as multidimensional arrays and sparse matrices, commonly used in numerical applications. The goal of this package is to provide reusable software components that address many of the portability and maintenance problems with C++ codes.

TNT provides a distinction between interfaces and implementations of TNT components. For example, there is a TNT interface for two-dimensional arrays which describes how individual elements are accessed and how certain information, such as the array dimensions, can be used in algorithms; however, there can be several implementations of such an interface: one that uses expression templates, or one that uses BLAS kernels, or another that is instrumented to provide debugging information. By specifying only the interface, applications codes may utilize such algorithms, while giving library developers the greatest flexibility in employing optimization or portability strategies.

Minpack includes software for solving nonlinear equations and nonlinear least squares problems. Five algorithmic paths each include a core subroutine and an easy-to-use driver. The algorithms proceed either from an analytic specification of the Jacobian matrix or directly from the problem functions. The paths include facilities for systems of equations with a banded Jacobian matrix, for least squares problems with a large amount of data, and for checking the consistency of the Jacobian matrix with the functions.

This package provides the headers, man pages, examples, and static library.

ASTEVAL is a safe(ish) evaluator of Python expressions and statements, using Python's ast module. The idea is to provide a simple, safe, and robust miniature mathematical language that can handle user-input. The emphasis here is on mathematical expressions, and so many functions from numpy are imported and used if available.

Many Python lanquage constructs are supported by default, These include slicing, subscripting, list comprehension, conditionals (if-elif-else blocks and if expressions), flow control (for loops, while loops, and try-except-finally blocks). All data are Python objects, and built-in data structures (dictionaries, tuple, lists, numpy arrays, strings) are fully supported by default.

Many of the standard builtin Python functions are available, as are all mathemetical functions from the math module. If the numpy module is installed, many of its functions will also be available. Users can define and run their own functions within the confines of the limitations of asteval.

There are several absences and differences with Python, and asteval is by no means an attempt to reproduce Python with its own ast module. Some of the most important differences and absences are:

  • Variable and function symbol names are held in a simple symbol table (a single dictionary), giving a flat namespace.
  • creating classes is not supported.
  • importing modules is not supported.
  • function decorators, yield, lambda, exec, and eval are not supported.
  • files can only be opened in read-only mode.

In addition, accessing many internal methods and classes of objects is forbidden in order to strengthen asteval against malicious user code. .

This package installs the library for Python 3.

The core of BRiAl is a C++ library, which provides high-level data types for Boolean polynomials and monomials, exponent vectors, as well as for the underlying polynomial rings and subsets of the powerset of the Boolean variables. As a unique approach, binary decision diagrams are used as internal storage type for polynomial structures. On top of this C++-library a Python interface is provided. This allows parsing of complex polynomial systems, as well as sophisticated and extendable strategies for Groebner base computation. BRiAl features a powerful reference implementation for Groebner basis computation.

This package contains the BRiAl Python 3 module.

Bumps er et sæt af rutiner til kurvetilpasning og usikkerhedsanalyse fra et bayesiansk perspektiv. Udover traditionelle optimeringsprogrammer, der søger efter det bedste minimum, de kan finde i søgeområdet, tilbyder bumps usikkerhedsanalyse, der undersøger alle gyldige minima og finder konfidensintervaller på parametre baseret på usikkerheden i de målte værdier. Bumps er blevet brugt for systemer med op til 100 parametre med snævre begrænsninger på parametrene. Fuld usikkerhedsanalyse kræver hundredvis af tusindvis af funktionsevalueringer, som kun er muligt for billige funktioner, systemer med mange processorer eller masser af tålmodighed.

Bumps indeholder flere traditionelle lokale optimeringsprogrammer såsom Nelder-Mead simplex, BFGS og differentiel evolution. Bumps usikkerhedsanalyse bruger Markov chain Monte Carlo til at udforske parameterområdet. Selvom programmet blev oprettet til kurvetilpasningsproblemet, kan Bumps udforske enhver funktion for sandsynlighedstæthed, såsom dem defineret af PyMC. Bumps usikkerhedsanalyse fungerer specielt godt med korrelerede parametre.

Bumps kan bruges som et bibliotek i dine egne programmer, eller som en ramme til at tilpasse, med en fuld grafisk brugerflade til at håndtere dine modeller.

dmsh: "The worst mesh generator you'll ever use."

Inspired by distmesh, dmsh is slow, requires a lot of memory, and isn't terribly robust either.

On the plus side, it's got a usable interface, is pure Python (and hence easily installable on any system), and if it works, it produces pretty high-quality meshes.

Combined with optimesh, dmsh produces the highest-quality 2D meshes in the west.

Example capabilities:

  • Primitives
  • circle, rectangle, polygon
  • halfspace
  • Combinations
  • difference
  • nonconstant edge length
  • union
  • intersection
  • Transformations
  • rotation, translation, scaling
  • Local refinement

Når der oprettes mesh'er for FEM/FVM-beregninger, så er din geometri nogle gange så simpel, så du ikke skal bruge en kompleks mesh-opretter (som pygmsh, MeshPy, mshr, pygalmesh, dmsh), men noget simpelt og hurtigt, der gør brug af strukturen for domænet.

Eksempler: Triangle, Rectangle, Regular polygon, Disk, Möbius strip, Sphere (overflade), Ball (fast), Tube, Cube.

Mpi4py-fft er en Pythonpakke til at beregne Fast Fourier Transforms (FFT'er). Store tabeller er distribueret og kommunikation håndteres under kølerhjelmen af MPI for Python (mpi4py). For at distribuere store tabeller bruger vi en ny og fuldstændig generisk algoritme, der tillader at ethvert indeks for en flerdimensionel tabel distribueres. Vi kan distribuere bare et indeks (en slab-dekomposition), to indekssæt (blyants dekomposition) eller endda flere for tabeller i højere dimensioner.

I mpi4py-fft er der også inkluderet en Pythongrænseflade til FFTW-biblioteket. Denne grænseflade kan bruges uden MPI, meget lig pyfftw, og endda for reel til reel tranformeringer, såsom diskrete cosine eller sine-tranformeringer.

Pakken tilbyder en Pythongrænseflade til FFTW, men med MPI-parallelisering. Dette aktiverer stærk skalering testet med 16.000 kerner, eller svag skalering testet med 2.000 kerner. Algoritmen er dokumenteret på https://arxiv.org/abs/1804.09536.

Pakken numexpr evaluerer multiple-operator tabeludtryk mange gange hurtigere end NumPy kan. Pakken accepterer udtrykket som en streng, analyserer det, omskriver det mere effektivt og kompilerer det til hurtigere Pythonkode løbende. Det er det næstbedste i forhold til at skrive udtrykket direkte i C og kompilere det med en specialiseret just-in-time-kompiler (JIT), dvs. det kræver ikke en kompiler på kørselstidspunktet.

Optlang is a Python package for solving mathematical optimization problems, i.e. maximizing or minimizing an objective function over a set of variables subject to a number of constraints. Optlang provides a common interface to a series of optimization tools, so different solver backends can be changed in a transparent way. Optlang's object-oriented API takes advantage of the symbolic math library sympy to allow objective functions and constraints to be easily formulated from symbolic expressions of variables.

Pythonic wrapper around FFTW, the speedy FFT library. The ultimate aim is to present a unified interface for all the possible transforms that FFTW can perform.

Both the complex DFT and the real DFT are supported, as well as arbitrary axes of abitrary shaped and strided arrays, which makes it almost feature equivalent to standard and real FFT functions of numpy.fft (indeed, it supports the clongdouble dtype which numpy.fft does not).

pyFFTW is BSD-licensed and should not be confused with python-fftw, a GPL-licensed python module with the same aim of providing python bindings to FFTW3. Or python3-gpyfft, which provides bindings to the OpenCL FFT library clFFT.

This package provides the Python 3 bindings.

Biblioteket tilbyder en af arkitekturen uafhængig API til at udtrykke vektoroperationer på data. Kode skrevet med denne API kan så senders til en af flere motorer såsom Vc, eller en scalar-implementering. Dette gør, at man kan få den bedste ydelse på platforme understøttet af Vc uden at miste flytbarhed for arkitekturer uden understøttelse såsom ARM og PowerPC, for eksempel, hvor scalar-motoren kan bruges i stedet uden at kræve ændringer i brugerkode.

Dets hovedfunktioner er implementeringer af den grundlæggende aritmetik for mange matematiske områder: Primes fields, Extensions Fields, Finite Fields, Finite Rings, Polynomials, Algebraic numbers, og Arbitrary precision integers og rationals (C++-omslag over gmp).

Givaro tilbyder også datastrukturer og skabelonklasser for manipulering af grundlæggende algebraobjekter såsom vektorer, matricer (dense, sparse, structured), univarate polynomialer (og derfor rekursive multivariate).

Biblioteket indeholder forskellige programmoduler og er fuldt kompatibelt med LinBox' lineære algebrabibliotek og Athapascanmiljøet, som tillader parallel programmering.

Dette er en tom overgangspakke, da Debian ikke længere indeholder udviklerdokumentation for Givaro. Denne »givaro-dev«-pakke kan fjernes fra systemet, når ingen andre pakker afhænger af den.

UG is a flexible software tool for the numerical solution of partial differential equations on unstructured meshes, with a focus on multigrid methods. It has a very powerful grid manager, which supports two- and three-dimensional grids with mixed element types. The grids can be adaptively refinement using either classic red/green-refinement, or pure red refinement with hanging nodes. All this is fully parallelized and can run on large distributed machines.

The version in this package has been built with the necessary flags for use with the Dune software system.

This package contains the development files.

Et konveks polyeder er sættet af punkter der tilfredsstiller en begrænset familie af lineære uligheder. Studiet af toppunkter og ekstreme stråler for sådanne systemer er vigtigt og brugbart i f.eks. matematik og optimering. I en fælles fortolkning svarer det at finde toppunkter på en (bundet) polyeder til at finde det konvekse skrog (bundede uligheder) på et (arbitrær dimensionelt) punktsæt. Lrs (omvendt leksikografisk søgning) har to vigtige funktioner som kan være meget vigtige for bestemte programmer: Det virker i præcis aritmetik, og det forbruger hukommelse proportionalt med inddata, uanset hvor stort uddata er.

Denne pakke indeholder de valgfrie teksthoveder og en symbolsk henvisning til biblioteket uden versionsnummer, nyttig for udviklere.

MTJ is designed to be used as a library for developing numerical applications, both for small and large scale computations. The library is based on BLAS and LAPACK for its dense and structured sparse computations, and on the Templates project for unstructured sparse operations.

MTJ uses the netlib-java project as a backend, which can be set up to use machine-optimised BLAS libraries for improved performance of dense matrix operations, falling back to a pure Java implementation. This ensures perfect portability, while allowing for improved performance in a production environment.

Sollya er både et værktøjsmiljø og et bibliotek for sikker kodeudvikling med kommatal. Det tilbyder en nem måde at udføre beregninger med mange aritmetiske præcisionsinterval. Det er specielt målerettet den automatiske implementering af matematiske kommatalsbiblioteker.

Oprindelig blev Sollya lavet mere specifikt til folk, der implementerer numeriske funktioner i matematiske biblioteker (f.eks. exp, arccos, tanh, etc.). Siden da har værktøjet udviklet sig og er nu blevet interessant nok ikke kun for udviklere af matematiske biblioteker, men også for alle som ønsker at udføre numeriske eksperimenter i et miljø, som er sikkert med hensyn til afrundingsfejl.

Denne pakke tilbyder det statiske bibliotek, symbolske henvisninger og teksthovedfiler krævet for udvikling.

This package consists of a couple of optimised tools for doing things that can roughly be considered "group-indexing operations". The most prominent tool is aggregate.

aggregate takes an array of values, and an array giving the group number for each of those values. It then returns the sum (or mean, or std, or any, ...etc.) of the values in each group. You have probably come across this idea before, using matlab accumarray, pandas groupby, or generally MapReduce algorithms and histograms.

There are different implementations of aggregate provided, based on plain numpy, numba and weave. Performance is a main concern, and so far this implementation comfortably beats similar implementations in other packages (check the benchmarks).

Sollya er både et værktøjsmiljø og et bibliotek for sikker kodeudvikling med kommatal. Det tilbyder en nem måde at udføre beregninger med mange aritmetiske præcisionsinterval. Det er specielt målerettet den automatiske implementering af matematiske kommatalsbiblioteker.

Oprindelig blev Sollya lavet mere specifikt til folk, der implementerer numeriske funktioner i matematiske biblioteker (f.eks. exp, arccos, tanh, etc.). Siden da har værktøjet udviklet sig og er nu blevet interessant nok ikke kun for udviklere af matematiske biblioteker, men også for alle som ønsker at udføre numeriske eksperimenter i et miljø, som er sikkert med hensyn til afrundingsfejl.

Denne pakke tilbyder kommandolinjeværktøjet Sollya.

The package is enhanced by the following packages: libsollya-dev sollya-doc

AMG is one of the most effective iterative methods for solution of equation systems arising, for example, from discretizing PDEs on unstructured grids. The method can be used as a black-box solver for various computational problems, since it does not require any information about the underlying geometry. AMG is often used not as a standalone solver but as a preconditioner within an iterative solver (e.g. Conjugate Gradients, BiCGStab, or GMRES).

AMGCL builds the AMG hierarchy on a CPU and then transfers it to one of the provided backends. This allows for transparent acceleration of the solution phase with help of OpenCL, CUDA, or OpenMP technologies. Users may provide their own backends which enables tight integration between AMGCL and the user code.

AMG is a header-only C++ library, with the headers provided by this package.

The MAGMA project aims to develop a dense linear algebra library similar to LAPACK but for heterogeneous/hybrid architectures, starting with current "Multicore+GPU" systems.

The MAGMA research is based on the idea that, to address the complex challenges of the emerging hybrid environments, optimal software solutions will themselves have to hybridize, combining the strengths of different algorithms within a single framework. Building on this idea, we aim to design linear algebra algorithms and frameworks for hybrid manycore and GPU systems that can enable applications to fully exploit the power that each of the hybrid components offers.

This package contains the headers and the static libraries.

TestU01 is a software library, implemented in the ANSI C language, and offering a collection of utilities for the empirical statistical testing of uniform random number generators.

TestU01 implements several types of random number generators in generic form, as well as many specific generators proposed in the literature or found in widely-used software. It provides general implementations of the classical statistical tests for random number generators, as well as several others proposed in the literature, and some original ones. These tests can be applied to the generators predefined in the library and to user-defined generators. Specific tests suites for either sequences of uniform random numbers in [0,1] or bit sequences are also provided, as well as basic tools for plotting vectors of points produced by generators and more advanced tools for more involved tests and usage.

This package contains the static libraries and symbolic links that developers using the TestU01 libraries will need.

levmar is a native ANSI C implementation of the Levenberg-Marquardt optimization algorithm. Both unconstrained and constrained (under linear equations, inequality and box constraints) Levenberg-Marquardt variants are included. The LM algorithm is an iterative technique that finds a local minimum of a function that is expressed as the sum of squares of nonlinear functions. It has become a standard technique for nonlinear least-squares problems and can be thought of as a combination of steepest descent and the Gauss-Newton method. When the current solution is far from the correct on, the algorithm behaves like a steepest descent method: slow, but guaranteed to converge. When the current solution is close to the correct solution, it becomes a Gauss-Newton method.

This package contains the header file and the demo program.
