Joint structured/non structured parallelism exploitation through data flow

Structured parallel programming promises to raise the level of abstraction p erceived by programmers when implementing parallel applications. In the meanwhile, however, it restricts the freedom of programmers to implement arbitrary parallelism exploitation patterns. In this work we discuss a data flow implementation methodology for skeleton based structured parallel programming environments that easily integrates arbitrary, user-defined parallelism exploitation patterns while preserving most of the b enefits typical of structured parallel programming models.
