The definitive version was published in Proceedings of the 5th ACM SIGPLAN Workshop on Declarative Aspects of Multicore Programming: http://doi.acm.org/10.1145/1708046.1708054S-Net is a declarative coordination language and component technology aimed at modern multi-core/many-core architectures and systems-on-chip. It builds on the concept of stream processing to structure dynamically evolving networks of communicating asynchronous components. Components themselves are implemented using a conventional language suitable for the application domain. This two-level software architecture maintains a familiar sequential development environment for large parts of an application and offers a high-level declarative approach to component coordination. In this paper we present a conservative language extension for the placement of components and component networks in a multi-memory environment, i.e. architectures that associate individual compute cores or groups thereof with private memories. We describe a novel distributed runtime system layer that complements our existing multithreaded runtime system for shared memory multicores. Particular emphasis is put on efficient management of data communication. Last not least, we present preliminary experimental data

A survey of algorithmic skeleton frameworks: high‐level structured parallel programming enablers

“…Its contributions are the purity of its coordination approach, which provides a clear‐cut separation of the behaviour and structure of a parallel program, and its performance‐oriented approach to the solution of computational problems 126. SAC has been recently augmented to support multicore architectures 127.…”

S+Net: extending functional coordination with extra-functional semantics

“…As data movement is then exposed in the language semantics, mapping and managing the application to parallel platforms becomes simpler. S-Net is specified in [13,10] and has been reported on in many published works, including [2,4,5,3,6,9,1,8,14,15].…”
