    摘要： Examples of techniques for processor mode switching are disclosed. In one example implementation according to aspects of the present disclosure, a computer-implemented method for processor mode switching to cause a processing system to switch a mode of a processor of a plurality of processors, wherein each processor of the plurality of processors is one of an active processor or an inactive processor, and wherein each active processor is in one of a first mode and a second mode may include: setting a processor threshold; determining whether a number of active processors exceeds the processor threshold; and responsive to determining that the number of active processors exceeds the processor threshold, switching the mode of the processor from the first mode to the second mode.

    摘要： A computing system is configured to maintain equivalency of independent structures located in different coupling facilities. The computing system includes a first coupling facility and a second coupling facility different from the first coupling facility. The first coupling facility includes a first structure that receives a first data modification based on a modification command requested by an application executed by an operating system. The second coupling facility in signal communication with the first coupling facility and includes a secondary structure that receives a second data modification based on the first data modification applied to the first structure. The first coupling facility outputs a Push List Structure Object (PLSO) command data block to the second coupling facility. The PLSO command data block indicates the first data modification applied to the first structure.

    摘要： A computing system is configured to maintain equivalency of independent queues located in different coupling facilities. The computer system includes a first coupling facility and a second coupling facility. The first coupling facility receives a plurality of different commands instructing the first coupling facility to load data into a first structure. The first coupling facility generates a first command data block including first data corresponding to a received first command and a first sequence value indicating a sequence at which the first data was loaded into the first structure with respect to remaining data corresponding to the plurality of commands. A second coupling facility includes a second structure and a second queue. The second coupling facility receives the first command data block from a first queue of the first coupling facility and loads the first data from the second queue into the second structure based on the first sequence value.
