Parallel programming with data driven model

In this paper, bye present a new powerful method for parallel program representation called Data Driven Graph (DDG). DDG takes all advantages of classical Directed Acyclic graph (DAC) and adds much more. Simple definition, flexibility and ability to represent loops and dynamically created tasks. With DDG, scheduling becomes an efficient tool for increasing performance of parallel systems. DDG is not only a parallel program model, it also initiates a new parallel programming style, allows programmer to write a parallel program with minimal difficulty. We also present our parallel program development tool with support for DDG and scheduling.
