ScaFi: A Scala DSL and Toolkit for Aggregate Programming.

Supported by current socio-scientific trends, programming the global behaviour of whole computa-tional collectives makes for great opportunities, but also significant challenges. Recently, aggregate computing has emerged as a prominent paradigm for so-called collective adaptive systems program-ming. To shorten the gap between such research endeavours and mainstream software development and engineering, we present SCAFI, a Scala toolkit providing an internal domain-specific language, libraries, a simulation environment, and runtime support for practical aggregate computing systems development.(c) 2022 Published by Elsevier B.V.
