Distribution of work and data for parallel grid assembly

Improvements in Parallel Chimera Grid Assembly

“…In the phase III implementation Prewitt et al 6 distributed the work of the grid assembly across multiple FE processes using data decomposition techniques. The basis for decomposition was the grids or groupings of grids called superblocks.…”

“…Modi cations in the work distribution of the grid assembly lessened the parallel performance of the ow solver and, thus, the parallel performance of the overall simulation. 5 Prewitt et al 6 performed the rst parallel, chimera CFD solution of a dynamic problem that used a data decomposition of the grid assembly separate from that of the ow solver. However, large load imbalances were seen in the grid assembly function, and the relatively small number of grids used in the test problem did not offer much opportunity for scalability.…”
