GRAPHICAL APPLICATION FOR BUILDING DISTRIBUTED APPLICATIONS
A graphical application development tool for developing parallel computation applications. The tool facilitates insertion of computational elements by a drag-and-drop operation onto a canvas area for creating a computational graph. The graphical application tool reduces the barriers to the development of parallel computation applications by entry-level developers, for example, by allowing these users to write applications by using a graphical tool, thereby avoiding complexities of having to write well-formed code and learning a new language. The tool includes built-in functionality that allows the developer to write arbitrary code (e.g., C#) to perform various functions on massive amounts of data.
