flushed by the CLFLUSHOPT instruction. For the same reason, the RDMA Read is not needed in this case. The Send message must contain a list of all cache lines that were written by the stream of RDMA Write(s) so that the CLFLUSHOPT can be utilized to flush
each cache line.</span><span style="font-size:9.0pt;font-family:"Verdana","sans-serif""><o:p></o:p></span></p>
