Thanks Micheal.<br>
<br>
Can I confirm that no memory beyond that specified in the WR for the
Send op is not actually written to.<br>
<br>
The reason I'm interested in this is that I'm thinking about
registering a large Memory Region to receive lots of smaller data
messages. This is to avoid the overhead of registering and
unregistering MRs. For RDMA Write, would windowing be the only option
to stop a sender writing beyond what the receiver was expecting?<br>
<br>
Regards,<br>
<br>
Steve.<br>
