<p class="MsoNormal">If an app wishes to create a passive endpoint, accept connections on it, and then post receives that will receive data coming from any remote connection on that endpoint, how exactly is that accomplished?
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My best guess is by using fi_rx_context, we can post a “shared” receive buffer via:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">fi_pendpoint(&pep);<o:p></o:p></p>
<p class="MsoNormal">fi_bind(pep, cmeq);<o:p></o:p></p>
<p class="MsoNormal">fi_listen(pep);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">fi_eq_sread(cmeq); // wait for CONNREQ 1<o:p></o:p></p>
<p class="MsoNormal">fi_endpoint(&cep1); // remote-specific EP<o:p></o:p></p>
<p class="MsoNormal">fi_accept(cep1);<o:p></o:p></p>
<p class="MsoNormal">fi_eq_sread(cmeq); // wait for COMPLETE 1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">fi_eq_sread(cmeq); // wait for CONNREQ 2<o:p></o:p></p>
<p class="MsoNormal">fi_endpoint(&cep2); // remote-specific EP<o:p></o:p></p>
<p class="MsoNormal">fi_accept(cep2);<o:p></o:p></p>
<p class="MsoNormal">fi_eq_sread(cmeq); // wait for COMPLETE 2<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">fi_rx_context(cep1, 0, &rxep); // get common EP for RX<o:p></o:p></p>
<p class="MsoNormal">fi_recv(rxep, buf, len);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now, a send from the remote endpoint associated with either cep1 or cep2 will land in buf, yes ?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m sure there are cases where support for this mode of operation is desired vs. not, what are the endpoint flags that would control whether this approach will work or not? I imagine that an endpoint that supports the above would NOT support
posting a receive directly to cep1 or cep2, and that endpoint that expect to post received to cep1 only for remote1 and cep2 for remote 2 (e.g. traditional Verbs RC endpoint) would not support this shared mode of operation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Assuming I am not too far off in the woods here, how is this shared/non-shared approach to receives communicated in the API?<o:p></o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
