Diagram that visually indicates targeted execution

A non-transitory computer accessible memory medium that stores program instructions executable by a processor to:

• display a first icon on a display, wherein the first icon has an interior, wherein the first icon is associated with a first execution target, and wherein the first icon specifies execution of a graphical program portion positioned in the interior of the first icon on the first execution target;
• display a first graphical program portion in the interior of the first icon, wherein the first graphical program portion comprises a plurality of interconnected nodes that visually indicate functionality of the first graphical program portion;
• display a second icon on the display, wherein the second icon has an interior, wherein the second icon is associated with a second execution target, and wherein the second icon specifies execution of a graphical program portion positioned in the interior of the second icon on the second execution target;
• and
• display a second graphical program portion in the interior of the second icon, wherein the second graphical program portion comprises a plurality of interconnected nodes that visually indicate functionality of the second graphical program portion;
• and
• display one or more wires connecting the first graphical program portion and the second graphical program portion;
• wherein during execution of the graphical program, the first graphical program portion executes on the first execution target, the second graphical program portion executes on the second execution target, and the first graphical program portion and the second graphical program portion communicate as specified by the one or more wires.
