1. A computer-implemented method comprising: executing, by a processor, a perform topology function instruction for requesting a configuration change of a topology of a plurality of processors of a configuration, the executing comprising: obtaining, based on the perform topology function instruction, a requested polarization change of the topology; determining whether the requested polarization change may be performed; initiating the requested polarization change, based on determining the requested polarization change may be performed; rejecting the requested polarization change, based on determining the requested polarization change is not to be performed; and setting a condition code, by the processor, to a value indicating whether the requested polarization change is initiated or rejected.
