A system is provided for handling a completion process in an remote data memory access (RDMA) environment having a RequestOut channel (16) and a ResponseOut channel (18), comprising: a descriptor list (12, 14) for each channel, wherein each descriptor list (12, 14) includes a message descriptor for each message in the channel; an update mechanism (25) for updating a message length field in the message descriptor with a sequence number of a last byte in the message whenever a channel swap occurs between the RequestOut channel (16) and the ResponseOut channel (18); an acknowledgement (Ack) completion system that examines values in a completion context (22) and compares a sequence number of a next to complete message with a last acknowledged sequence number to determine if the message should be completed; and a read request completion system that performs completion of a read request.</p> |
