ABSTRACT:
A method, system, and associated program code and data structures are provided for a message processing system in which messages are passed from source nodes to destination nodes. Notification of the arrival of the messages at the destination nodes can be effected by programmable source initiated interrupts or destination initiated interrupts. The source initiated interrupts are implemented as set fields embedded in the message packets sent from a source node to a destination node and trigger the requisite interrupt at the destination node upon message arrival. The destination initiated interrupts are implemented as pre-set fields in anticipatory buffers which are allocated at the destination node for incoming messages from the source node. Standard incoming message queue polling, as well as interrupt enabling and disabling functions are also provided, which together allow the system to selectively invoke interrupt or alternative strategies to notify destination nodes of arriving messages.
