    Abstract: A method is disclosed of scheduling jobs to be executed by a resource in a computer system wherein the jobs are grouped in classes, with the job classes vying for the resource's attention being arranged in a hierarchy. Each job class has a time-function value that controls when the job class is selected by the resource if processing time becomes available. Within a particular level of the hierarchy, scheduling priorities are defined by one or more time-based functions, each of which may be constant or dynamically varying. When constant time-based functions are used, each job class has a schedule value that remains fixed with time. When dynamic time-based functions are used, job class "time-function values" are modified to alter the timing by which the job class(es) acquire the resource.

    Abstract: The embodiment discloses a method and means for partitioning the resources in a data processing system into a plurality of logical partitions. Host control code may be embodied in programming, microcode, or by special hardware to enable highly efficient operation of a plurality of preferred guest programming systems in the different partitions of the system. The main storage, expanded storage, the channel, and subchannel resources of a system are assigned to the different logical partitions in the system to enable a plurality of preferred guest programming systems to run simultaneously in the different partitions. This invention automatically relocates the absolute addresses of the I/O channel and subchannel resources in the system to their assigned partitions. Also the absolute and virtual addresses of the different guest programming systems are relocated into, as well as page addresses for any expanded storage, their assigned partitions. The guest programming systems generally will be different operating systems. The logical CPU(s) of the guests are dispatched on one or plural real CPUs in the system using the S/370XA SIE (start interpretive execution) instruction. Special operations are provided, including the CPU alerting of other guests in different partitions using I/O interruption signalling. Interception is provided to handle special circumstances.
