Logical resource partitioning of a data processing system

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