The question concerns the DOCA RDMA library API from DOCA 3.1.0. In the DOCA Samples, there are Write Requester and Write Responder examples, and I’d like to know if there is a Write task synchronization mechanism for the Responder side. Since the Responder doesn’t need to submit a Receive/Read task after sending the memory descriptor to the Requester, no callback is triggered to indicate that the Requester has finished writing data to the Responder’s memory.
I know we can create a Send task for the Requester in the Write completion callback and a Receive task for the Responder to get an acknowledgment that the Write is completed, but this seems to introduce unnecessary overhead.
