Abstract: Various components are provided to manage a clustered environment. These components include a System Registry that provides a global data storage; a Configuration manager that stores data locally on nodes of the clustered environment and globally within the System Registry; a Liveness component to provide status of communications paths of the cluster; a Group Services component that provides services to one or more other components of the clustered environment; and a Resource Management component that communicates with one or more resource controllers of the clustered environment. Each of the components of the clustered environment has one or more data and/or functional dependencies on one or more other components of the environment. However, relationships between the components are created such that the data and functional dependencies form an acyclic graph (i.e., a cycle of dependency relationships is avoided).

Abstract translation: 提供了各种组件来管理群集环境。 这些组件包括提供全局数据存储的系统注册表; 一个配置管理器，用于将数据本地存储在集群环境的节点上，并在系统注册表中全局; 提供集群通信路径状态的Liveness组件; 组服务组件，为集群环境的一个或多个其他组件提供服务; 以及与集群环境的一个或多个资源控制器进行通信的资源管理组件。 集群环境的每个组件对环境的一个或多个其他组件具有一个或多个数据和/或功能依赖性。 然而，创建组件之间的关系使得数据和功能依赖性形成非循环图（即，避免了依赖关系的循环）。

Abstract: To avoid the overflow problem, in a graphics display system which employs matrix concatenation for coordinate transformation and matrix element precision equal to that inherent to the system, which can cause an out-of-bounds location of a data element, number translation shift factors are introduced for the last row of the matrix which when used to operate on matrix elements. This will maintain the elements within the physical boundaries of the graphics base by preventing overflow. The disclosed modification can be implemented in microcode in a commercially availably graphics display system such as the IBM 5080 Graphics System.
