In heterogeneous environment with data dependencies volume increases with the task

rapid growth and task processing time can make full use of computer resources

puts forward the problems can be decomposed job scheduling strategy

the task scheduling strategy according to the children in the DAG hierarchical relationships by using job scheduling

biodegradable characteristics

some of the graph can be decomposed DAGs job down into a two layer tree layer

thus make the system to adjust the dynamic load

and makes the computer system load balance of the computer

the optimum performance remarkably improved efficiency.
