A system includes a first processing device and a second processing device, each of which is coupled to a NIC implemented with an RDMA interface. The NICs are capable of rendezvous flows of RDMA write exchange. In an example where the first NIC is at the sender side and the second NIC is at the receiver side, a rendezvous flow is initiated by an execution of a RDMA write operation by the second NIC. The second NIC provides at least an address of a buffer in the second processing device to the first NIC through the RDMA write operation. Then the first NIC initiates a RDMA write operation to send data in a buffer in the first processing device to the second NIC. The second NIC may acknowledge receipt of the data with the second NIC. The second NIC can update a CI of the WQE based on the acknowledgement.
