Abstract: A method and apparatus of a device that builds a target using a plurality of processing units is described. In an exemplary embodiment, the device receives a build file for the target, where the build file identifies a plurality of dependencies and the first target is depended on a second target. In addition, the device generates a directed acyclic graph for the first target from the plurality of dependencies. Furthermore, the device transforms the directed acyclic graph by transforming the first set of dependencies to a second set of dependencies and the second set of dependency includes the first dependency that is from a first node in the first target to a second node of a second target.

Abstract: Systems, methods and articles of manufacture for determining impact correlations from a calculation graph for calculating taxes. The system includes a computing device, a data store in communication with the computing device and a tax preparation software application executable by the computing device. The tax preparation software application has a tax calculation engine, a tax calculation graph, and an impact chain engine. The tax calculation engine is configured to perform a plurality of tax calculation operations based on the tax calculation graph. The impact chain engine is configured to analyze the tax calculation graph and determine an impact correlation between a change in a value of a first node caused by a change in a value of a second node utilizing an impact chain which includes both the first node and the second node.
