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.
