Abstract
Variants of dataflow specification models are widely used to synthesize streaming applications for distributed-memory parallel processors. We argue that practice of specifying streaming applications using structurally-rigid dataflow models, implicitly prohibits a number of platform oriented transformations and hence, has limited portability and scalability with respect to platform resources, such as the number of its processors. We motivate Functionally-cOnsistent stRucturally-MalLEabe Streaming Specification, dubbed FORMLESS, which refers to raising the abstraction level beyond fixed-structure dataflow to address its portability and scalability limitations. To demonstrate the promise of the idea, we develop a design space exploration scheme to customize the application model for the target platform before synthesizing software. Experiments with several common streaming applications, implemented on soft multiprocessors, demonstrate improved portability and scalability over conventional dataflow specification models, and highlight practical benefits of malleable specifications.
