About Free Software
- The Free Software Foundation's mission is to preserve,
protect and promote the freedom to use, study, copy, modify, and redistribute computer
software, and to defend the rights of Free Software users.
- The FSF Europe was launched March 10th 2001
and works towards all European aspects of Free Software and especially the GNU Project.
- The GNU Scientific Library (GSL) is
a collection of routines for numerical computing. The routines have been written from
scratch by the GSL team in ANSI C. The library covers areas like complex numbers,
random numbers, special functions, minimization, etc.
- The OpenBabel
project is a library and executable for converting traditional
chemistry file formats. The program has some chemical knowledge and
can e.g. determine whether or not chemical bonds exist. It is licensed
under the GPL.
- The NetCDF
(network Common Data Form) is an interface for array-oriented data
access and a library that provides an implementation of the
interface. The netCDF library also defines a machine-independent
format for representing scientific data. Together, the interface,
library, and format support the creation, access, and sharing of
scientific data. The license is basically public domain with some
- HDF5 is a general
purpose library and file format for storing scientific data. HDF5 can
store two primary objects: datasets and groups. A dataset is
essentially a multidimensional array of data elements, and a group is
a structure for organizing objects in an HDF5 file. Using these two
basic objects, one can create and store almost any kind of scientific
data structure, such as images, arrays of vectors, and structured and
unstructured grids. The license is basically public domain with some
- The Python homepage. The Python
license is GPL compatible.
- PyMOL is a FREE and
OPEN-SOURCE molecular visualization system. License is free as in
- SWIG is a software development
tool that connects programs written in C and C++ with a variety of
high-level programming languages. SWIG is primarily used with common
scripting languages such as Perl, Python, Tcl/Tk, Ruby, Guile and
MzScheme, however the list of supported languages also includes
non-scripting languages such as Java and Eiffel. License is public domain.
- Numerical Python
adds a fast, compact, multidimensional array language facility to Python.
License is OSI approved.
- The MPI standard.
- The LAM-MPI (Local Area
Multicomputer) is an MPI programming environment and development
system for heterogeneous computers on a network. With LAM, a dedicated
cluster or an existing network computing infrastructure can act as one
parallel computer solving one problem. License is BSD.
- MPICH is
a freely available, portable implementation of MPI, the Standard for
message-passing libraries. License is BSD-like.
- Charm++ and Converse are
libraries for scaling parallel processing to many (thousands)
processors. Proprietary license.
- Aegis is a
transaction-based software configuration management system. It
provides a framework within which a team of developers may work on
many changes to a program independently, and Aegis coordinates
integrating these changes back into the master source of the program,
with as little disruption as possible. License is GPL.
- SCons a software construction
tool where user input is described in Python. License is public domain.
- CVS homepage. Most modern OSes
come with CVS preloaded. License is GPL.
- Automake and
Autoconf are the
well known tools that let you run ./configure; make; make
install (as a user). The license is GPL.
- Grace is a
WYSIWYG 2D plotting tool for the X Window System and M*tif. Grace runs
on practically any version of Unix. As well, it has been successfully
ported to VMS, OS/2 and Win9*/NT (some minor functionality may be
missing, though). Grace is a descendant of ACE/gr, also known as
Xmgr. License is GPL.
- OpenDX gives you new control
over your data...and new insights into their meaning. Yet OpenDX is
easy to use because it lets you visualize data in ways you have never
dreamed of--without getting bogged down in the technology. IBM public
