Abstract

We propose a new duplication-basedDAG scheduling algorithm for heterogeneous computing environments. Contrary to the traditional approaches, proposed algorithm traverses the DAG in a bottom-up fashion while taking advantage of task duplication and task insertion. Experimental results on random DAGs and three different application DAGs show that the makespans generated by the proposed DBUS algorithm are much better than those generated by the existing algorithms, HEFT, HCPFD and HCNF.
