Reliability processing of remote direct memory access
Abstract
Methods and systems for monitoring remote transmissions of messages among a plurality of nodes are described. A processing element in a first node may allocate a sequence number to a request to read and/or update data in a second node. The processing element may be different from main processors of the first node. The processing element may send the message and the sequence number to the second node. The processing element may modify a status of the sequence number to an active state, indicating a transmission of the message is pending. The processing element may, in response to a response from the second node, modify the status of the sequence number to an inactive state, indicating a completed transmission of the message. The processing element may, in response to no response from the second node within a time period, resend the message and the sequence number to the second node.
