Patents by Inventor James William Watts, III

James William Watts, III has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8813053
    Abstract: Systems and methods for parallel incomplete LU (ILU) factorization in distributed sparse linear systems, which order nodes underlying the equations in the system(s) by dividing nodes into interior nodes and boundary nodes and assigning no more than three codes to distinguish the boundary nodes. Each code determines an ordering of the nodes, which in turn determines the order in which the equations will be factored and the solution performed.
    Type: Grant
    Filed: September 25, 2012
    Date of Patent: August 19, 2014
    Assignee: Landmark Graphics Corporation
    Inventors: Qinghua Wang, James William Watts, III
