Towards Software Component Assembly Language Enhanced with Workflows and Skeletons

We explore the possibilities offered by a programming model supporting components, workflows and skeletons. In particular we describe how Stcm (Spatio-Temporal Component Model), an already existing programming model supporting components and workflows, can be extended to also provide algorithmic skeleton concepts. Programmers are therefore enabled to assembly applications specifying both temporal and spatial relations among components and instantiating predefined skeleton composite components to implement all those application parts that can be easily modeled with the available skeletons. We discuss preliminary results as well as the benefits deriving from Stkm (Spatio-Temporal sKeleton Model) adoption in a couple of real applications.
