    Abstract: 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.

    Abstract: A first and a second operand are compared. If they are equal, the contents of register R1 + 1 are stored at the second-operand location, and the specified CPU or CPUs in the configuration are cleared of all TLB table entries of the designated type formed through the use of the replaced entry in storage, and all lower-level TLB table entries formed through the use of the cleared higher-level TLB table entries. A valid DAT table entry is replaced with a new entry, and the Translation Lookaside Buffer (TLB) is purged of any copies of (at least) the single entry on all CPUs in the configuration. If the first and second operands are unequal, the second operand is loaded at the first-operand location. The comparison result is indicated by the condition code. A method, system and a computer program product are provided.

    Abstract translation: 比较第一和第二操作数。 如果它们相等，则寄存器R1 + 1的内容存储在第二操作数位置，并且配置中指定的CPU或CPU将清除通过使用替换的条目形成的指定类型的所有TLB表项 存储和通过使用清除的更高级TLB表条目形成的所有较低级别的TLB表条目。 有效的DAT表条目被替换为新条目，并且翻译后备缓冲区（TLB）被清除组态中所有CPU上的（至少）单个条目的任何副本。 如果第一和第二操作数不相等，则第二个操作数被加载到第一个操作数位置。 比较结果由条件码表示。 提供了一种方法，系统和计算机程序产品。
