PyGLM is a Python extension library which brings the OpenGL Mathematics (GLM) library to Python.

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

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.

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.

Aris is a program for performing logical proofs. It supports propositional and predicate logic, as well as Boolean algebra and arithmetical logic. In addition to its predefined inference and equivalence rules, Aris also supports references to older proofs. Its use of standard logical symbols and its natural deduction interface make it easy to use for beginners.

HYPRE is a software library of high performance preconditioners and solvers for the solution of large, sparse linear systems of equations. It features multigrid solvers for both structured and unstructured grid problems.

4ti2 implements algorithms for solving algebraic, geometric and combinatorial problems on linear spaces. Among others, it solves systems of linear equations, computes extreme rays of polyhedral cones, solves integer programming problems and computes Markov bases for statistics.

Mlucas performs Lucas-Lehmer primality testing of Mersenne numbers in search of a world-record prime. You may use it to test any suitable number as you wish, but it is preferable that you do so in a coordinated fashion, as part of the Great Internet Mersenne Prime Search (GIMPS). Mlucas also includes a simple Python script for assignment management via the GIMPS project's Primenet server.

PETSc, the Portable, Extensible Toolkit for Scientific Computation, is a suite of data structures and routines for the scalable (parallel) solution of scientific applications modeled by partial differential equations. It employs the MPI standard for all message-passing communication. petsc4py provides Python bindings to almost all functions of PETSc.
