TDFL: A task-level data flow language

The Task-Level Dataflow Language is a graphical language for architecture-independent parallel programming and is intended for the writing of new programs and the adaptation of existing ones. It is the first coarse-grained dataflow language that supports dynamic modification of program graphs. It provides a systematic use of program constructs to support particular programming styles, such as nondeterminism, iteration, and replication. It has been used successfully in a course on parallel programming. © 1990.
