## Data Driven decomposition ### Data Driven decomposition
Data is divided across processors, It is the default decomposition when a decomposition is not available yet, it basically divide the data consistently across processors regardless of geometrical meaning or communication Data is divided across processors, It is the default decomposition when a decomposition is not available yet, it basically divide the data consistently across processors regardless of geometrical meaning or communication
