JavaSymphony is a high-level programming model for performance oriented distributed and parallel Java applications, which allows the programmer to control parallelism, load balancing, and locality at a high level of abstraction. In this paper, we describe an extension of JavaSymphony that deals with distributed workflow applications as graphs of software components, which can be executed on a distributed set computers. Workflows are not limited to DAGs, but also cover complex control flow including loops. Furthermore, we introduce a novel approach for workflow scheduling based on the HEFT algorithm and resource brokerage for a heterogeneous set of computers. We demonstrate the effectiveness of our approach with two real-world applications and compare our techniques against the widely known DAGMan Condor scheduler.
