<p>I forgot to ask ...</p>
<p><br>
</p>
<p>When sending a message, the Tx context/endpoint can just send. No real problem.</p>
<p>When receiving, suppose I have two Rx contexts and I post a receive on both and a message arrives - if they are tagged messages, then presumably whichever Rx has the right tag will receive it - if untagged, is it just round robiin, or chance/race to see
which cq is given the receive?</p>

<p>Hi list,</p>
<p><br>
</p>
<p>I am creating a scalable endpoint, which I've used previously with multiple Tx contexts, and it worked fine, but I hadn't realized you could also have multiple Rx contexts - so I added them recently ... but</p>
<p><br>
</p>
<p>I get completions on the Tx CQ, but not on the Rx CQ (GNI provider).</p>
<p><br>
</p>
<p>My initialization for both is essentially the same</p>
<p>Loop N thread counter</p>
<p> <span>fi_tx_context</span>(i ... ep_tx)</p>
<p> create_cq</p>
<p> <span>bind_queue_to_endpoint(ep_tx, cq)</span></p>
<p><span> <span>enable_endpoint</span><br>
</span></p>
<p><br>
</p>
<p></p>
<p> <span>fi_rx_context</span>(i ... ep_rx)</p>
<p> create_cq</p>
<p> <span>bind_queue_to_endpoint(ep_rx, cq)</span></p>
<p><span> <span>enable_endpoint</span><br>
</span></p>
<p><span>end loop</span></p>
<p><span>scalable_endpoint_bind (address vector)</span></p>
<p><span><br>
</span></p>
<p><span>Sends are posted to the tx context/endpoint and cq</span></p>
<p><span>Recvs to the rx context/ep + cq</span></p>
<p><span><br>
</span></p>
<p><span>Why might there be a difference between the Tx and Rx completions? Any idea what might need tweaking<br>
</span></p>

<p>Thanks</p>
