Abstract
Mechanisms for collective send operations on a system area network are provided. The mechanisms of the illustrative embodiments provide for the creation, modification, and removal of collective send queues (CSQs) that allow the upper level protocol (ULP) used by a consumer to send the same message to a collective set of queue pairs (QPs). In order to use the transport services of a CSQ, a consumer process posts a write work request (WR) to the CSQ. The write WR causes a write work queue element (WQE) to be generated and placed in the CSQ. A channel interface (CI) is provided that effectively copies the write WQE to all of the send queues (SQs) of the QPs in the QP set associated with the CSQ. When all the QPs complete processing of their respective write WQEs, the HCA releases all data segments referenced by the write WR.
