Gnuplot is a portable command-line driven graphing utility. It was originally created to allow scientists and students to visualize mathematical functions and data interactively, but has grown to support many non-interactive uses such as web scripting. It is also used as a plotting engine by third-party applications like Octave.

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 geometry classes.

This package uses PLT trampolines to provide a BLAS and LAPACK demuxing library.

This package provides a parser for the BTOR2 format used by Boolector.

libflame is a portable library for dense matrix computations, providing much of the functionality present in LAPACK, developed by current and former members of the SHPC group in the Institute for Computational Engineering and Sciences at The University of Texas at Austin. libflame includes a compatibility layer, lapack2flame, which includes a complete LAPACK implementation.

mCRL2 (micro Common Representation Language 2) is a formal specification language for describing concurrent discrete event systems. Its toolset supports analysis and automatic verification, linearisation, simulation, state-space exploration and generation, and tools to optimise and analyse specifications. Also, state spaces can be manipulated, visualised and analysed.

PETSc, pronounced PET-see (the S is silent), is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations.

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.

CLP is a high quality linear programming solver. Its main strengths are its dual and primal Simplex algorithms. It also has a barrier algorithm for linear and quadratic objectives. There are limited facilities for nonlinear and quadratic objectives using the Simplex algorithm.

CryptoMiniSat is an incremental SAT solver with both command line and library (C++, C, Python) interfaces. The command-line interface takes a CNF as an input in the DIMACS format with the extension of XOR clauses. The library interfaces mimic this and also allow incremental solving, including assumptions.

Gmsh is a 3D finite element grid generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh's own scripting language.

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.

More than 1500 numerical integration schemes for line segments, circles, disks, triangles, quadrilaterals, spheres, balls, tetrahedra, hexahedra, wedges, pyramids, n-spheres, n-balls, n-cubes, n-simplices, and the 1D/2D/3D/nD spaces with weight functions exp(-r) and exp(-r2) for fast integration of real-, complex-, and vector-valued functions.

This package provides a C++ implementation of the Louvain community detection algorithm.

SuperLU_DIST is a parallel extension to the serial SuperLU library. It is targeted for distributed memory parallel machines. SuperLU_DIST is implemented in ANSI C, and MPI for communications.

This is a filter for HDF5 that uses the Blosc compressor; by installing this filter, you can read and write HDF5 files with Blosc-compressed datasets.

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.

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

The itex2MML utility is a stream filter. It takes text with embedded itex equations, converts the itex equations to MathML, and outputs the resulting text.

This package provides a SAT solver based on conflict-driven clause learning.

HPCombi is a C++17 header-only library using the SSE and AVX instruction sets, and some equivalents, for very fast manipulation of combinatorial objects such as transformations, permutations, and boolean matrices of small size.

MiniSat is a minimalistic, open-source SAT solver, developed to help researchers and developers alike to get started on SAT.

This package provides the C library of RBio. It can be used for reading and writing sparse matrices in the Rutherford/Boeing format.

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.
