US Patent 10331495 Generation of directed acyclic graphs from task routines

An apparatus including a processor to: parse comments of multiple task routines to identify I/O parameters; generate a visualization of a DAG to include a visual representation of each task routine, wherein each representation includes a task graph object of the task routine, at least one input data graph object that represents an input to the task routine and that includes a visual indication of at least one characteristic of the input; and at least one output data graph object that represents an output of the task routine and that includes a visual indication of at least one characteristic of the output; in the I/O parameters, identify each dependency between an output of one task routine and an input of another; for each identified dependency, augment the visualization with a dependency marker that visually links the visual representations of each associated pair of task routines; and visually output the visualization.
