Abstract
In the companion paper, we discussed the applicability of a recursive spatial decomposition (RSD) based automatic meshing procedure for concurrent implementation. This paper describes an automatic substructuring scheme based on RSD of the domain, that can be closely integrated with the RSD-based automatic meshing procedure. The hierarchical data structures used to represent RSD-based automatically derived meshes also provide a one-to-one mapping between spatially decomposed sub- domains and analytical substructures. Such a hierarchical organization of the substructures and the inherent parallelism of RSD are exploited to design the substructuring scheme suitable for parallel processing. A systematic simulation of parallel computational environments is used to evaluate the performance of the substructuring scheme for coarse-grain architectures. Speed-ups from vectorization alone are also reported.
