Abstract
Partitioning a given computational mesh for parallel processing
is a very active research topic in parallel computation
technology. A large number of solution algorithms
exists for the a priori, static partitioning problem. The
most efficient algorithms are implemented in program libraries
like Chaco or Metis.
Nevertheless, the partitioning problem is known to be combinatorial hard. There is no algorithm producing definitely the best solution. All attempts implement more or less efficient heuristics which may fail due to the special properties of the partitioning problem. Additionally, the parallel machine used to solve the computational problem and the solution procedure itself have significant influence on the suitability of a given partitioning. We propose a special software tool for evaluating the partitioning results with respect to the characteristics of a chosen parallel machine and the application of an iterative solver. We approximate the iteration cycle time by a theoretical model of the hard- and software. The comparison of a number of partitionings is based on these practical performance figures. purchase the full-text of this paper (price £20)
