HiGHS provides serial and parallel solvers for large-scale sparse linear programming (LP), mixed-integer programming (MIP), and quadratic programming (QP) models

primesieve is a command-line program and C/C++ library for quickly generating prime numbers. It is very cache efficient, it detects your CPU's L1 & L2 cache sizes and allocates its main data structures accordingly. It is also multi-threaded by default, it uses all available CPU cores whenever possible i.e. if sequential ordering is not required. primesieve can generate primes and prime k-tuplets up to 264.

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.

HDF5 is a suite that makes possible the management of extremely large and complex data collections.

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.

wxMaxima is a graphical user interface for the Maxima computer algebra system. It eases the use of Maxima by making most of its commands available through a menu system and by providing input dialogs for commands that require more than one argument. It also implements its own display engine that outputs mathematical symbols directly instead of depicting them with ASCII characters.

wxMaxima also features 2D and 3D inline plots, simple animations, mixing of text and mathematical calculations to create documents, exporting of input and output to TeX, and a browser for Maxima's manual including command index and full text searching.

Ruy is a matrix multiplication library. Its focus is to cover the matrix multiplication needs of neural network inference engines. Its initial user has been TensorFlow Lite, where it is used by default on the ARM CPU architecture.

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)

HDF5 is a suite that makes possible the management of extremely large and complex data collections.

LibPoly is a C library for manipulating polynomials to support symbolic reasoning engines that need to reason about polynomial constraints.

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The library also provides threshold-based ILU factorization preconditioners.

nauty (No AUTomorphisms, Yes?) is a set of procedures for computing automorphism groups of graphs and digraphs.

nauty computes graph information in the form of a set of generators, the size of the group, and the orbits of the group; it can also produce a canonical label. The nauty suite is written in C and comes with a command-line interface, a collection of command-line tools, and an Application Programming Interface (API).

This package provides the static libraries required to run programs compiled against the nauty library.

The GNU Scientific Library is a library for numerical analysis in C and C++. It includes a wide range of mathematical routines, with over 1000 functions in total. Subject areas covered by the library include: differential equations, linear algebra, Fast Fourier Transforms and random numbers.

Lis is a parallel software library for solving discretized linear equations and eigenvalue problems that arise in the numerical solution of partial differential equations using iterative methods.

FLANN is a library for performing fast approximate nearest neighbor searches in high dimensional spaces. It implements a collection of algorithms and a system for automatically choosing the best algorithm and optimum parameters depending on the dataset.

FLANN is written in C++ and contains bindings for C, Octave and Python.

PnetCDF is a high-performance parallel I/O library for accessing Unidata's NetCDF, files in classic formats, specifically the formats of CDF-1, 2, and 5.
