Skywriting is a programming language and execution engine for
distributed, parallel computation. Like previous frameworks (such
as MapReduce and Dryad), it masks the complexity of distributed
programming. Unlike those frameworks, it offers a full general-purpose
programming language for expressing distributed coordination, which
enables developers to implement algorithms using arbitrary task
structures.
