ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to computer software adapted for execution on a computer network. More specifically, this invention relates to the management and distribution of computer application program execution on a computer network containing various resources.
2. Description of Related Art
Many modern business computer applications require the division and distribution of processing tasks between several computational resources. A variety of systems and processes have been developed to manage and/or distribute computer processes across a network. Some such approaches include, PVM, developed by Oak Ridge National Labs, which is a set of programming libraries to allow a user to build “multicomputers,” which is a set of independent machines on a network that share application processing to create heterogeneous network computing; Inferno, a Lucent Technologies programming language, “virtual machine,” and communications protocol; Jini, produced by Sun Microsystems, is a set of Java classes and a distributed computing model; Millennium, a Microsoft product that is comparable to Jini; Linda, a set of distributed computing functions, developed by Dr. David Gelemter of Yale University, to simplify parallel programming tasks distributed to multiple processors; JetSend, developed by Hewlett-Packard, lets peripheral devices communicate across a network; and Papers, a parallel processing mechanism that includes a hardware component for sharing memory and other resources, developed by Dr. Hank Dietz at Perdue University. (The inventor and applicant also wish to acknowledge the testing and evaluation support of Richard Newton of Kaysville, Utah.) Typically, these and other known techniques work on only limited networks, lack the ability to distribute application program processing across multiple computers, and/or work on only certain network systems or only with certain programming languages.
