Hi Sagi,
Another question, from what I understand from the code, the client
always rdma_writes data on writes (with imm) from a remote pool of
server buffers dedicated to it. Essentially all writes are immediate (no
rdma reads ever). How is that different than using send wrs to a set of
pre-posted recv buffers (like all others are doing)? Is it faster?
At the very beginning of the project we did some measurements and saw,
that it is faster. I'm not sure if this is still true
Its not significantly faster (can't imagine why it would be).
What could make a difference is probably the fact that you never
do rdma reads for I/O writes which might be better. Also perhaps the
fact that you normally don't wait for send completions before completing
I/O (which is broken), and the fact that you batch recv operations.
I don't know how do you come to the conclusion we don't wait for send
completion before completing IO.
We do chain wr on successfull read request from server, see funtion
rdma_write_sg,
I was referring to the client side
