ABSTRACT:
Send queues provided in an InfiniBand hardware adapter receive a single transmission from a connected computer system which includes work request information, address vector, and message data. This information is sufficient for the adapter to generate packet header information and to send the requested message, thereby providing a low latency sending mechanism. The system stores completion information in tables each dedicated to one of the send queues.
