decomposed into tasks which are assigned to different processors. Efficient use
of the machine requires that each processor have about the same amount of work
to do and that the quantity of interprocessor communication is kept small.
Finding an optimal decomposition is provably hard, but due to its practical
importance, a great deal of effort has been devoted to developing heuristics
for this problem.
The decomposition problem can be addressed in terms of graph partitioning. Rob
Leland and I have developed a variety of algorithms for graph partitioning and
implemented them into a package we call Chaco. The code is being used at most
of the major parallel computing centers around the world to simplify the
development of parallel applications, and to ensure that high performance is
obtained. Chaco has contributed to a wide variety of computational studies
including investigation of the molecular structure of liquid crystals,
evaluating the design of a chemical vapor deposition reactor and modeling
automobile collisions.

CGAL is a collaborative effort of several sites in Europe and Israel. The goal
is to make the most important of the solutions and methods developed in
computational geometry available to users in industry and academia in a C++
library. The goal is to provide easy access to useful, reliable geometric
algorithms.
The CGAL library contains:
* the Kernel with geometric primitives such as points, vectors, lines,
predicates for testing things such as relative positions of points, and
operations such as intersections and distance calculation.
* the Basic Library which is a collection of standard data structures and
geometric algorithms, such as convex hull in 2D/3D, (Delaunay)
triangulation in 2D/3D, planar map, polyhedron, smallest enclosing
circle, and multidimensional query structures.
* the Support Library which offers interfaces to other packages, e.g., for
visualisation, and I/O, and other support facilities.

I'd like to reintroduce VTK 4.3 to the ports tree to
facilitate building a new port, Caret 5.3. Starting with
VTK 4.4, support for "float" coordinates has been dropped
from many functions. The Caret code will require significant
changes to compile with VTK 4.4. Since the Caret developers
do not yet have a timeline for upgrading to VTK 4.4, I'd
like to reintroduce VTK 4.3 for the interim. Only the vtk
base and vtk-headers are essential. Below are shar files
for these two trees. They are based on the original vtk
4.3 port. The only modifications are:
1. The folder names are changed from vtk and vtk-headers
to vtk43 and vtk43-headers to prevent a collision with the
current vtk in /usr/ports/math.
2. PREFIX is set to ${LOCALBASE}/vtk43 to prevent a collision
with the current vtk installation.

area of parametric surfaces.
Features :
* 3D, 4D, 5D and 6D HyperObjects visualization.
* Full support of all functions (like C language).
* Support of mouse event in the drawing area (Left:Rotate, Right:scale
and Midle:translate).
* Animation an Morph effect.
* Povscript and Mesh file generation(and Run if povray is installed).
VRML2 and OBJ files also supported.
* More than 100 well known examples.
It is based on transforming an expression into a bytecode and precalculating
constant parts of it.

A major advantage of Asymptote over other graphics packages is that
it is a programming language, as opposed to just a graphics program:
it can therefore exploit the best features of script (command-driven)
