摘要：
A method is provided for determining whether a logical processor of an information processing system has access to an address space of the information processing system. An instruction is issued by a first processor, the instruction referencing a target logical processor and a target address space. In response to the instruction, first information is checked to determine whether the target logical processor is running. When it is determined that the target logical processor is not running, second information is checked by a host program to determine whether the target logical processor has access to the target address space.
