Specifying components in graph-based programs

A non-transitory computer readable medium with software for processing a graph-based program specification stored thereon, the software including instructions for causing a computing system to:

• receive user input including a graph-based program specification that includes links, data ports, and components, each component corresponding to a processing task and having at least one of the data ports, wherein the data ports include scalar data ports and collection data ports,
• render the graph-based program specification on a user-interface,
• form subsets of the components based on identified entry points and exit points, the entry points and exit points having been identified based at least in part on a link that connects a collection data-port of a component in one subset with a scalar data-port of a component in another subset,
• render a visual representation of the subsets within the user-interface, and
• for each of the subsets, generate code, wherein the code causes a runtime system to perform processing tasks corresponding to the components in the subset.

A computing system for processing a graph-based program specification, the computing system including:

• a user interface configured to:
• receive user input including a graph-based program specification that includes links, data ports, and components, each component corresponding to a processing task and having at least one of the data ports, wherein the data ports include scalar data ports and collection data ports, and

• rendering a visual representation of the subsets within the user-interface, and
• for each of the subsets, generating code, wherein the code causes a runtime system to perform processing tasks corresponding to the components in the subset.
