Abstract
In response to a request from a central processing unit (CPU)(i.e., firmware) of a node, a transfer control unitof a direct memory access (DMA) controllertransmits a message and data to another discretionary nodeby way of a serial bus, a switchor the like. In this event, the firmware stores data to be transmitted, a message, and a descriptor thereof in memory. In the case of requesting the transmission of the message, the descriptor contains a flag indicating 'whether or not there is a need to wait for a response from the data transmission destination'. If the flag is set to ON, the transfer control unitnotifies the firmware of a simulated completion immediately instead of waiting for a completion response from the transmission destination node
