Abstract:
1. A computer program product for managing quiesce requests, the computer program product comprising: a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a signal, the program instructions readable by a processing circuit to cause the processing circuit to perform a method comprising: receiving a quiesce request at a quiesce controller from a requesting processor, the requesting processor being one of a plurality of processors in a multi-processor system; determining that the quiesce request is not accepted by the quiesce controller; based on the quiesce request being not accepted by the quiesce controller, generating a reject message configured to indicate that the quiesce request has been rejected; holding the reject message until a quiesce command is broadcast to the multi-processor system, the quiesce command based on a different quiesce request; and sending the reject message to the requesting processor based on the broadcast of the quiesce command being detected by the quiesce controller.
