Abstract
A computer program device and product is provided for timely processing of data. The computer program device comprises a program storage device readable by a digital processing apparatus and a program means including instructions executable by the digital processing apparatus by designating at least one set of queues in the queuing mechanism as input queues and another as output queues; issuing a signal adapter instruction to provide initiative to check content of any or all queues in the queuing mechanism; specifying initiate-output or initiate-input appropriately by means of said signal adapter instruction to cause associated adapter to asynchronously process said output or input queues; and causing synchronization by means of said signal adapter instruction by signaling the associated data queues to update all entries in order to render them current. The computer program product is for use with a computer system and has a main storage in processing communication with an interface element having adapters for storing a queuing mechanism storing data. It comprises of a data storage device including a computer usable medium having computer readable program means for ensuring proper …
