• FastFlow

This thesis describes an implementation of a tool, which runs in a web browser, that supports development of FastFlow programs built by composing FasFlow “parallel building blocks”. The tool, based on existing open source code of an online diagramming library, provides the FastFlow programmer with features to draw any legal building block compositions on the screen and to save that compositions to local storage for further processing. The tool allows only valid compositions to be drawn and in addition provides automatic completion of compositions such as automatically providing the needed communication channels. The tool is mostly developed using javascript. The output of the tool has been agreed to be suitable for further processing such as for automatic application or template code generation.
