Abstract: A distributed computing system conforms to a multi-level, hierarchical organizational model. One or more control nodes provide for the efficient and automated allocation and management of computing functions and resources within the distributed computing system in accordance with the organization model. The model includes four distinct levels: fabric, domains, tiers and nodes that provide for the logical abstraction and containment of the physical components as well as system and service application software of the enterprise. A user, such as a system administrator, interacts with the control nodes to logically define the hierarchical organization of distributed computing system. The control nodes are responsible for all levels of management in accordance with the model, including fabric management, domain creation, tier creation and node allocation and deployment.

Abstract: Apparatus for controlling a gaming device including a plurality of rotatable reels provided with indicia has an input circuit associated with the reels for detecting reel positions at every instant in time. A computing circuit is connected to the input circuit for receiving reel position signals and maintaining data on reel positions. Connected to the computing circuit is a comparative, or win, circuit arranged for receiving reel position signals from the computing circuit and for comparing indicia on each of the reels as a function of the position of the reels for determining if a predetermined match exists. A pay circuit connected to the comparative circuit is actuated by a match detected in the comparative circuit to effect a pay-out by a hopper assembly of the associated gaming device. Included in the input circuit is an optical sensing assembly arranged for cooperating with gaps and openings provided on the reels for determining positions of the reels.
