Abstract: An apparatus is disclosed for visual programming for creating a program with a visual user interface. The visual programming apparatus has a screen storage unit for storing multiple screens to be employed with the program; a screen creating unit for creating the multiple screens to be employed with the program and storing the multiple screens in the screen storage unit; a screen flow creating unit for creating a screen flow indicating a flow of processes by displaying on an edit screen the multiple screens stored in the screen storage unit in a compressed manner and specifying a link between the multiple compressed screens on the edit screen; a screen flow information extracting unit for extracting data of a link from the screen flow created by the screen flow creating unit; and a code creating unit for creating a source code from the data of the link extracted by the screen flow information extracting unit and from data of the screen.

Abstract: A system and method for vectorizing a non-innermost loop of a nested loop. Iterative loops of a nested loop are analyzed to determine if they can be vectorized (vector legality). If more than one iterative loop can be vectorized, a selection criteria is applied to select the iterative loop which would provide the most return from vectorization (vector selection).
