Abstract:
1. A method of making a computer program product to facilitate processing of queues of a processing environment, the method comprising: storing first instructions for causing a computer to determine that a queue of the processing environment has transitioned from a no replies pending state to a reply pending state, wherein the queue is indirectly accessible to user programs, and wherein the no replies pending state is a state in which the queue is empty, and the reply pending state is a state in which the queue is not empty, and wherein the storing comprises storing the first instructions on a tangible computer storage medium; storing second instructions for causing a computer to enable the queue for interruption, the enabling comprising employing a process adjunct processor queue (PQAP) instruction to enable the queue for interruption, wherein the PQAP instruction employs general registers storing third instructions for causing a computer to initiate, by a processor, an interrupt for the queue, wherein the initiating is based on enabling the queue and determining that the queue has transitioned from the no replies pending state to the reply pending state, wherein the interrupt is initiated based on the queue transitioning from an empty state to a non-empty state, and the interrupt is not initiated based on the queue not transitioning from the empty state to the non-empty state, and wherein the storing comprises storing the third instructions on a tangible computer storage medium.
