A parallel blackboard system is described that allows multiple knowledge source instantiations to execute in parallel using a shared-memory blackboard approach. New classes of control knowledge are defined that use information about the relationships between system goals to schedule tasks - this control knowledge is implemented in the DVMT application on a Sequent multiprocessor using BB1-style control heuristics. The usefulness of the heuristics is examined by comparing the effectiveness of problem-solving with and without the heuristics (as a group and individually). Problem solving with the new control knowledge results in increased processor utilization and decreased total execution time.","doi":null,"url":"https://ijcai.org/proceedings/1991/3","pdf":"https://ijcai.org/proceedings/1991/0003.pdf","markdown":"https://ijcai.org/proceedings/1991/3.md","bibtex":"https://ijcai.org/proceedings/1991/bibtex/3","volume":{"slug":"1991","title":"Proceedings of the Twelfth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1991","url":"https://ijcai.org/proceedings/1991/","year":1991,"location":"Sydney, New South Wales, Australia","dates":"24-30 August 1991","editors":"John Mylopoulos and Ray Reiter","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Architectures & Languages","track":"Architectures & Languages","number":3,"pages":{"first":15,"last":20},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
