LinAsm is collection of very fast and SIMD optimized assembly written libraries for x86-64.

It implements many common and widely used algorithms for array manipulations: searching, sorting, arithmetic and vector operations, unit conversions; fast mathematical and statistic functions; numbers and time converting algorithms; finite impulse response (FIR) digital filters; spectrum analysis algorithms, Fast Hartley transformation; CPU cache friendly functions and extremely fast abstract data types (ADT) such as hash tables b-trees, and much more.

The p4est software library enables the dynamic management of a collection of adaptive octrees, conveniently called a forest of octrees. p4est is designed to work in parallel and scales to hundreds of thousands of processor cores.

The Java HDF5 Interface (JHI5) uses the Java Native Interface to wrap the HDF5 library, which is implemented in C.

primecount is a command-line program and C/C++ library that counts the number of primes no greater than x (maximum 1031) using highly optimized implementations of the combinatorial prime counting algorithms.

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

CAMD is a set of routines for ordering a sparse matrix prior to Cholesky factorization (or for LU factorization with diagonal pivoting). It is a variant of AMD which has the the option to apply constraints to the ordering.

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.

feedgnuplot is a tool to plot realtime and stored data from the command line, using gnuplot. It can read data from a pipe or file, make a variety of transformations, and render the result in the terminal or with an external viewer.

SCOTCH is a set of programs and libraries which implement the static mapping and sparse matrix reordering algorithms developed within the SCOTCH project. Its purpose is to apply graph theory, with a divide and conquer approach, to scientific computing problems such as graph and mesh partitioning, static mapping, and sparse matrix ordering, in application domains ranging from structural mechanics to operating systems or bio-chemistry.

Arccon is part of the Arcane framework, providing core functionality for the Arcane development platform.

GKlib is a library of various helper routines and frameworks used by software from KarypisLab, such as METIS.

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.

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 DUNE UG grid classes.

GNU Units converts numeric quantities between units of measure. It can handle scale changes through adaptive usage of standard scale prefixes (micro-, kilo-, etc.). It can also handle nonlinear conversions such as Fahrenheit to Celsius. Its interpreter is powerful enough to be used effectively as a scientific calculator.

IT++ is a C++ library of mathematical, signal processing and communication classes and functions. Its main use is in simulation of communication systems and for performing research in the area of communications. The kernel of the library consists of generic vector and matrix classes, and a set of accompanying routines. Such a kernel makes IT++ similar to MATLAB, GNU Octave or SciPy.

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.

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 computer algebra system--an alternative to Wolfram.

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.

This header-only C++ library implements conversion to and from half-precision floating point formats.

SuiteSparse is a suite of sparse matrix algorithms, including: UMFPACK, multifrontal LU factorization; CHOLMOD, supernodal Cholesky; SPQR, multifrontal QR; KLU and BTF, sparse LU factorization, well-suited for circuit simulation; ordering methods (AMD, CAMD, COLAMD, and CCOLAMD); CSparse and CXSparse, a concise sparse Cholesky factorization package; and many other packages.

This package contains all of the above-mentioned parts.

pagmo is a C++ scientific library for massively parallel optimization. It is built around the idea of providing a unified interface to optimization algorithms and to optimization problems and to make their deployment in massively parallel environments easy.

Arcane is a development environment for parallel numerical calculation code. It supports the architectural aspects of a calculation code, such as data structures for meshing and parallelism, as well as more environment-related aspects such as dataset configuration.
