I trust you guys on this, but have you thought about whether blueflame
makes sense for RDMA read requests? After all, an RDMA read requires
the responder to send potentially a large amount of data to complete,
and even for small requests I would think that latency-sensitive apps
would avoid it. Is there an MPI implementation or other app that you
know of where this really helps?
You can run the ib_read_lat test and see the latency improvement for
each message size.
And we have customers that this improvement is important for them.
