Roland:
when RDMA is used, a message is transferred from card A (in node
A) to card B (in node B), card B delivers the message to to user buffer,
and sends ACK to card A, but ACK is lost due to switch fail. So process
on node A get fail for this transfer, but process on node B check the
memory and get the message(success).
If send/recv(SRQ) is used, is it possible that process on node A
get failure, but process on node B successfully get the message ?
