MPI version of the Neighbourhood Algorithm
A parallel implementation of
the Neighbourhood Algorithm, a direct search technique for nonlinear
inverse problems. Typically such problems are characterized by a
multi-dimensional parameter space, compute-intensive forward models and
complex data-misfit functions. Further details of this approach can be
found at http://rses.anu.edu.au/~malcolm/na.
A parallel implementation of the Neighbourhood Algorithm is also
available
through a point and click interface in the CADI toolkit

CADI toolkit
The CADI toolkit is a graphical user interface designed to allow
scientists to take advantage of distributed computing resources without
needing to do any distributed programming themselves. It runs either on
a single machine, on a cluster computer, or even on participating
desktop machines on a local network. See the CADI toolkit homepage
for details. |

3D Fast Marching software
A software package that models seismic wave front propagation using the
fast marching method (FMM) in 3-D spherical coordinates for complex
layered media. Traveltimes and ray paths of phases comprising one or
more bounces and/or transmissions can be tracked in the presence of
complex structures (e.g. subduction zones, heterogeneous crust). Direct
transmissions in continuous media can also be tracked. The main goal of
the package is to act as a general tool for computing traveltimes in
laterally heterogeneous media at a variety of scales; example
applications include local or regional scale tomography (the software
already includes an option to calculate the Frechet derivatives),
refraction/wide-angle reflection imaging, and earthquake location. For
more details, see the
3D fast marching web page.

TRABOX - A 3-D seismic ray tracing program
Program TRABOX is an initial value and boundary value (i.e. two-point)
seismic ray tracing program in Cartesian co-ordinates. It was initially
written by Malcolm Sambridge in 1987 at the Research School of Earth
Sciences, Australian National
University. The most recent modification was in May 2001. It
has been tested under three different compilers, each giving the same
results on the 5 test problems. These are sun f77, GNU g77 and
Compaq-Alpha f77.
Full details
of TRABOX can be found at TRABOX
website. |

Tomoeye - Tomographic model visualisation software
Tomoeye is a set of programs
for tomographic model visualization written in MatLab 6.1 script. It
can be used
not only for tomographic studies but also for visualizing the
distribution of
any three-dimensional fields in the Earth.

Finite Element, Volume, and Difference software
A range of purpusedly designed finite element, finite volume
and finite difference codes t
o solve partial differential equations commonly encountered in the
Earth Sciences, can also b
e made available to collaborating teams and taylored to specific
applications. These include
a three dimensional model to solve the heat transport equation in the
Earth's crust, includin
g the effect of conduction, tectonic advection, topographically-driven
fluid flow, production by radiogenic elements and the effect of a
finite amplitude, time-varying topography. This m
odel is particularly useful to interpret complex thermochronological
datasets.

Landform Evolution software
A range of landscape evolution models are also available that
include many landforming mechanims such as fluvial erosion, deposition
and transport, soil production and transport, and
glacial erosion.
