Abstract: Multiple instances of operating systems execute cooperatively in a single multiprocessor computer wherein all processors and resources are electrically connected together. The single physical machine with multiple physical processors and resources is subdivided by software into multiple partitions, each with the ability to run a distinct copy, or instance, of an operating system. At different times, different operating system instances may be loaded on a given partition. Resources, such as CPUs and memory, can be dynamically assigned to different partitions and used by instances of operating systems running within the machine by modifying the configuration. The partitions themselves can also be changed without rebooting the system by modifying the configuration tree. A grouping of partitions, a community, shares memory. Memory may be private to a particular partition or may be shared by partitions within a community.

The partitions themselves can also be changed without rebooting the system by modifying the configuration tree. Memory may be reconfigured into or out of a partition or community under software control. In general, memory may be in one of three states: private, shared, or unowned. Memory is private if it is “owned” by a single system partition.

Abstract: A system remote sensor network that uses distributed intelligent modules includes a control panel having at least one intelligent sensor loop for coupling intelligent sensors, i.e., sensors having a unique ID, with the control panel and at least one remote interface module having an interactive display. A graphic representation of the floor plan in vector form is stored in the panel and module memories. In addition, the vector location of each peripheral coupled to the intelligent sensor loops is stored in each module's memory. By storing the floor plan in vector form, both low and high detail display images can be displayed with minimum memory requirement. Upon the issuance of a display command generated either by a user or by the panel, the graphic representation of the floor plan and locations of the sensors is displayed on the remote interface module.
