- Description:
- Before a calculation can be performed on a parallel computer, it must
first be 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.
Chaco implements a variety of algorithms for graph partitioning and is
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.
Note: this port includes a patch provided by Walter Landry for use within
MBDyn.

Remove WWW entries moved into port Makefiles
Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles
It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.
Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.
There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

Most contributors copy an existing port when writing their own so reduce the

Before a calculation can be performed on a parallel computer, it must first be

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
