<div>
<p class="MsoNormal">Hi.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Quick update is 1000 nodes and 7 million reqs/sec :) - and the number of requests should be higher but we had some internal issues. We have a submission for barcelona to provide a lot more details.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">But a couple questions came during the exercise:<o:p></o:p></p>
</div>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1. Do we really need a volume in the VMs? On large clusters this is a burden, and local storage only should be enough?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2. We observe a significant delay (~10min, which is half the total time to deploy the cluster) on heat when it seems to be crunching the kube_minions nested stacks. Once it's done, it still adds new stacks gradually, so it doesn't look
like it precomputed all the info in advance<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Anyone tried to scale Heat to stacks this size? We end up with a stack with:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* 1000 nested stacks (depth 2)<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* 22000 resources<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">* 47008 events<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">And already changed most of the timeout/retrial values for rpc to get this working.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">This delay is already visible in clusters of 512 nodes, but 40% of the time in 1000 nodes seems like something we could improve. Any hints on Heat configuration optimizations for large stacks very welcome.<o:p></o:p></p>
</div>
<div>

<tt>Hi.</tt><br>
<br>
<tt>Just thought the Magnum team would be happy to hear :)</tt><br>
<br>
<tt>We had access to some hardware the last couple days, and tried some</tt><br>
<tt>tests with Magnum and Kubernetes - following an original blog post</tt><br>
<tt>from the kubernetes team.</tt><br>
<br>
<tt>Got a 200 node kubernetes bay (800 cores) reaching 2 million requests / sec.</tt><br>
<br>
<tt>Check here for some details:</tt><u><span style="color:blue"><br>

<br>
<tt>We'll try bigger in a couple weeks, also using the Rally work from</tt><br>
<tt>Winnie, Ton and Spyros to see where it breaks. Already identified a</tt><br>
<tt>couple issues, will add bugs or push patches for those. If you have</tt><br>
<tt>ideas or suggestions for the next tests let us know.</tt><br>
<br>
<tt>Magnum is looking pretty good!</tt><br>
<br>
<tt>Cheers,</tt><br>
<tt>Ricardo</tt><br>
