ABSTRACT:
A multi-nodal computing system is connected by a communication network. A first node of the multi-nodal system includes apparatus for transmitting an information transfer request to a second node, the request including identification data that the second node can use to access the selected information. The second node includes memory for storing the requested information and a message output control structure. A processor is responsive to received identification data from the first node to access selected information that is defined by the data. The processor is further responsive to the information transfer request to insert the identification data received from the first node directly into a message output control structure. The processor then initiates an output operation by employing the identification data in the message output control data structure to access the identified information and to communicate the information to the first node. In such manner, no processor interrupt is required (with software intervention) to enable the requested information to be transferred, as pointers to that information are already included in the message output control structure, with the output mechanism in the second node employing that output control structure to access and transmit the requested information.
