conditions, this kind of graph can be transformed into an extended DAG, called Hybrid DAG (HDAG), composed of tasks and super-tasks. With this, it becomes possible to model many applications in the form of hybrid workflows and go about scheduling them...

A workflow represents a complex activity that

is often modeled by a directed acyclic graph (DAG) in which

each vertex is a task and each directed edge represents both

precedence and communication. Recently, Hybrid DAG has...
