Performance and Load Balancing Other approaches Data distribution Domain decomposition 17. All processors have entire grid. Processors work on sub-grids. Processors broadcast entire sub-grid to all other processors. All processors have only a sub-grid.
Processors work on sub-grid.
Only boundary data is transferred to neighbors. You have to keep track of your neighbors 18. Domain Decomposition 19. All processors have entire T array. After every iteration, all processors broadcast their TW to all other processors.
