How to use ucp_put_nb?

[haipeng31]

In the client side, I invoke the following function:

1. ucp_put_nb to rdma_write remote addr
2. ucp_tag_send_nb to notify remote the previous rdma_write succeed

In the server side, I invoke the following funciton:

1. ucp_tag_recv_nb

My question is if In the server side, recv_nb's cb is called, can't I make sure that the ucp_put_nb is finished or in other words The server side can read the data wrote by the client side throught ucp_put_nb?

One more question is whether ucx support rdma_write_with_imme?

waiting for your reponses, tks
