A society model, which characterizes the behavior and procedure of offices, is proposed. It is our belief that an office system capable of dealing with all real office problems only through the modeling of the internal behavior of an office can be developed. In this society model, office entities are viewed as agents. An agent is modeled as a microsociety of interacting knowledge sources. Within the microsociety, there exists a microknowledge exchange system, which provides a set of microknowledge exchange protocols as a coordination system among those knowledge sources during their cooperative reasoning process. An office is then modeled as a society of various interacting agents using their knowledge to complete the office goals cooperatively.It is this unified view that allows offices to be modeled in a flexible and general way.
One of the most Important considerations for a dataflow multlprocessor is the algorithm by which the nodes of a program Ipmph are allocated for execution to its processors. In the case of the static type of architecture one must consider pipelining as well as spatial concurrency. This paper uses a graph partition.lag scheme to aid in the design of such algorithms and selection of the associated interconnection topology. The scheme first reflees the usual dataflow program graph and then partitions it into "trees? Our study shows that the hypercube interconnection a¢-¢ommodates these trees in a way that allows us to develop an algozlthm that places producer nodes (of a dataflow graph) nears their ¢onsume~s to keep the message path very short. The algorithm at~leves concurrency in simultaneous execution of subgraphs that involve parallel operations, e.g., array operations, and subgraphs ~t are highly Iteratlve or recurslve. An analytical model is given to evaluate the performance of the algorlthm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
