A method, system, and program for providing runtime graph parameters and conditional components for data flow graphs. Runtime parameters allow an application builder to defer the value of a parameter setting to runtime. The values of runtime parameters may be supplied by the end user or be derived from a combination of other runtime parameters or objects stored in an object repository. A developer may specify a prompt for each parameter and the conditions for displaying the prompt, which are used to determine a graphical user interface control for receiving the parameter value. A conditional components mechanism permits changes to a graph structure based on parameter values and computed metadata. Each component of a graph has a condition which controls whether or not that component will appear in the graph at runtime. The condition can be computed directly or indirectly through runtime parameters.

Parameterized graphs with conditional components

A system and method for parallelizing applications of script-driven software tools. Scripts in the software tool scripting language are automatically analyzed in order to produce a specification for a parallel computation plus a set of 'script fragments', the combination of which is functionally equivalent to the original script. The computational specification plus the script fragments are then executed by a parallel runtime system, which causes multiple instances of the original software tool and/or supplemental programs to be run as parallel processes. The resulting processes will read input data and produce output data, performing the same computation as was specified by the original script. The combination of the analyzer, runtime system, original software tool, and supplemental programs will, for a given script and input data, produce the same output data as the original software tool alone, but has the capability of using multiple processors in parallel for substantial improvements in overall 'throughput'. The invention includes computer program embodiments of an automatic script analyzer.
