HEALPix is a set of scientific tools implementing the Hierarchical Equal Area isoLatitude Pixelation of the sphere. As suggested in the name, this pixelation produces a subdivision of a spherical surface in which
every single pixel covers the same surface area. HEALPix provides various programs and libraries in C, C++, Fortran, GDL/IDL, Java, and Python which facilitate discretization, simulation, processing, analysis, and visualization of data on the sphere up to very high resolution. It is the state-of-the-art program used
in astronomy and cosmology to deal with massive full-sky data sets.

NeXus Scientific Data Format is a set of data storage objects and APIs for storing data commonly collected in neutron and synchrotron experiments, to simplify the exchange and processing of these data sets, and to ease the development of new methods of processing such data.

ppgplot is a Python package (extension) providing Python
bindings to the PGPLOT graphics library. It uses the
numeric or numarray Python modules to efficiently
represent and manipulate vectors and matrices.

SAOTrace is a suite of software designed to
simulate the as-built performance of grazing-angle
X-ray optics using the ray-tracing approach. It is
derived from portions of the NASA OSAC (Optical
Surface Analysis Code) software suite. It can
model nested conical as well as flat optical
designs, and includes the ability to model
arbitrary support structures and baffles. It can
model non-ideal multi-layer reflective coatings as
well as scattering from the optical surfaces.

MMTL (Multilayer Multiconductor Transmission
Line) is a 2-D and 2.5-D electromagnetic
modeling tool suite. It generates transmission
parameters and SPICE models from
descriptions of electronics interconnect
dimensions and materials properties.

GSEGYView is a viewer for seismic data in SEG-Y
format, its modifications, and many other related
formats aimed to store either petroleum
exploration data or seismology data. GSEGYView
features graphics hardware acceleration via OpenGL
for seismic data rendering, wiggle, variable area
and variable density seismic traces
representation, two-level sorting of seismic
traces by arbitratry keys in trace headers,
multiple windows for multiple files with separate
display parameters, easy seismic section
navigation and zoom with mouse wheel support, and
more.

The CFD General Notation System (CGNS) provides a
general, portable, and extensible standard for the
storage and retrieval of computational fluid
dynamics (CFD) analysis data. CGNS is designed to
facilitate the exchange of data between sites and
applications, and to help stabilize the archiving
of aerodynamic data.

Elemental is a C++ framework for distributed-memory dense linear algebra that strives to be fast, portable, and programmable. It can be thought of as a generalization of PLAPACK to element-by-element distributions that also makes use of recent algorithmic advances from the FLAME project. Elemental usually outperforms both PLAPACK and ScaLAPACK, however, it heavily relies on MPI collectives so a good MPI implementation is crucial. Both pure MPI and hybrid OpenMP-MPI configurations are supported.

LISPF4 is an InterLisp interpreter written in FORTRAN in the early 1980s. This version has been converted to C and given the ability to have commandline determination of the memory size.

OpenXyce is a parallel circuit simulator that was forked from the Xyce circuit simulation software from Sandia National Laboratories. It features parallel circuit simulation using MPI, SPICE compatible Netlists, and standard simulation algorithms, including harmonic balance.

for2html is a Perl script that translates Fortran sources into HTML pages, automatically generating forward and backward links to SUBROUTINE and FUNCTION calls.
