Expedited message transfer in a multi-nodal data processing system

A computing system including multiple nodes said system comprising:

• a communication network;
• a first node connected to said communication network and including means for transmitting an information transfer request that includes identification data usable by a node to access requested information and further data identifying a destination for said requested information;
• and
• a second node connected to said communication network for receiving said information transfer request, said second node including a memory for storing said requested information, a processor and a message output control data structure, said second node also including a processor that is responsive to identification data contained in said message output control data structure to access information from said memory, said processor further responsive to receipt of said information transfer request from said first node to insert said identification data contained in said information transfer request from said first node into said message output control data structure, said second node initiating an output operation, without performing an interrupt of said processor, by employing said message output control data structure and pointers to required data as included with said information transfer request from said first node, to access said requested information from said memory and to communicate said requested information to said destination.
