DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods. It supports the easy implementation of methods like Finite Elements (FE), Finite Volumes (FV), and also Finite Differences (FD).

This package contains the basic DUNE grid classes.

The dune-subgrid module marks elements of another hierarchical dune grid. The set of marked elements can then be accessed as a hierarchical dune grid in its own right. Dune-Subgrid provides the full grid interface including adaptive mesh refinement.

Vc provides portable, zero-overhead C++ types for explicitly data-parallel programming. It is a library designed to ease explicit vectorization of C++ code. Its types enable explicitly stating data-parallel operations on multiple values. The parallelism is therefore added via the type system. Vc has an intuitive API and provides portability between different compilers and compiler versions as well as portability between different vector instruction sets. Thus, an application written with Vc can be compiled for:

1. AVX and AVX2

2. SSE2 up to SSE4.2 or SSE4a

3. Scalar

4. MIC

5. NEON (in development)

6. NVIDIA GPUs / CUDA (in development)

HDF4 is a library and multi-object file format for storing and managing data between machines. HDF4 is an older hierarchical data format, incompatible with HDF5.

CGLM is an optimised 3D maths library for graphics software based on the GLSL specifications.

It's similar to the original C++ GLM library but written in C99 and compatible with C89.

Maxima is a system for the manipulation of symbolic and numerical expressions. It yields high precision numeric results by using exact fractions, arbitrary precision integers, and variable precision floating point numbers. This package variant uses ECL as the underlying Lisp implementation.

ScaLAPACK is a Fortran 90 library of high-performance linear algebra routines on parallel distributed memory machines. ScaLAPACK solves dense and banded linear systems, least squares problems, eigenvalue problems, and singular value problems.

Glucose is a SAT solver based on a scoring scheme introduced in 2009 for the clause learning mechanism of so called “Modern” SAT solvers. It is designed to be parallel.

SLEPc is a software library for the solution of large sparse eigenproblems on parallel computers. It can be used for the solution of linear eigenvalue 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.

A pure Ruby AsciiMath parsing and conversion library. AsciiMath is an easy-to-write markup language for mathematics.

This package provides a C++ interface to the NetCDF library for scientific data storage.

HDF-EOS2 is a software library built on HDF4 which supports the construction of data structures used in NASA's Earth Observing System (Grid, Point and Swath).

This package provides a computer algebra module for Lie groups. Documentation is available on http://www-math.univ-poitiers.fr/~maavl/pdf/LiE-manual.pdf.

The double-conversion library provides binary-decimal and decimal-binary routines for IEEE doubles. The library consists of efficient conversion routines that have been extracted from the V8 JavaScript engine.

Qhull computes the convex hull, Delaunay triangulation, Voronoi diagram, halfspace intersection about a point, furthest-site Delaunay triangulation, and furthest-site Voronoi diagram. The source code runs in 2-d, 3-d, 4-d, and higher dimensions. Qhull implements the Quickhull algorithm for computing the convex hull. It handles roundoff errors from floating point arithmetic. It computes volumes, surface areas, and approximations to the convex hull.

Qhull does not support triangulation of non-convex surfaces, mesh generation of non-convex objects, medium-sized inputs in 9-D and higher, alpha shapes, weighted Voronoi diagrams, Voronoi volumes, or constrained Delaunay triangulations.

SUNDIALS is a family of software packages implemented with the goal of providing robust time integrators and nonlinear solvers that can easily be incorporated into existing simulation codes.

Kiwi is an efficient C++ implementation of the Cassowary constraint solving algorithm. Kiwi has been designed from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. Memory savings are consistently > 5x.

NetCDF is an interface for scientific data access and a software library that provides an implementation of the interface. The netCDF library defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data.

This package provides a range of SAT solvers, including the sequential lingeling and its parallel variants plingeling and treengeling. A bounded model checker is also included.

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox for solving partial differential equations (PDEs) with grid-based methods.

This is the iterative solver template library which provides generic sparse matrix/vector classes and a variety of solvers based on these classes. A special feature is the use of templates to exploit the recursive block structure of finite element matrices at compile time. Available solvers include Krylov methods, (block-) incomplete decompositions and aggregation-based algebraic multigrid.

SPEX is a set of routines for sparse exact linear algebra. It contains the SPEX Left LU library for computing a sparse exact left-looking LU factorization for solving unsymmetric sparse linear systems.

OpenBLAS is a Basic Linear Algebra Subprograms (BLAS) library forked from the GotoBLAS2-1.13 BSD version.

The ELPA library provides efficient and scalable direct eigensolvers for symmetric matrices.

SuiteSparse is a suite of sparse matrix algorithms. This package contains a library with common configuration options.
