11:00:40 <openstack> The meeting name has been set to 'scientific_sig'
11:00:47 <oneswig> greetings
11:02:04 <janders> g'day oneswig
11:02:08 <janders> how are things?
11:02:41 <oneswig> Hi janders - going well thanks.  I have again not put any thought into preparing for the SIG meeting, alas :-(
11:03:08 <oneswig> Was just thinking about Lustre and Manila again - seems like a lot of people would be interested in this
11:03:33 <janders> yeah... I was never ever a fan of having NFS gateways in between
11:04:08 <verdurin> Morning. We certainly would be. Some new hardware specifically for Secure Lustre testing will be arriving soon.
11:04:11 <oneswig> Does take away much of the performance advantage
11:04:25 <oneswig> Hello verdurin, how timely!
11:04:41 * janders is looking up a picture that illustrates the issue very well
11:05:05 <oneswig> With the SIG spanning the globe, it's hard to bring every party to one place and time.
11:06:25 <oneswig> janders: your former colleagues at CSIRO were using BeeGFS, right? Were they also using Lustre?
11:07:46 <janders> parallel filesystem / native: https://www.travelweekly.com.au/wp-content/uploads/2019/05/Qantas-Dreamliner.png
11:08:06 <janders> parallel filesystem + NFS re-export: https://c8.alamy.com/comp/FJCA88/cook-transport-low-loader-truck-taking-a-wide-load-consisting-of-a-FJCA88.jpg
11:08:12 <janders> I reckon it's not far off...
11:08:43 <oneswig> ha ha!  Good analogy
11:08:52 <janders> oneswig I they were exploring Lustre towards the end of my time with CSIRO
11:09:56 <oneswig> janders: anyone there who would be a good contact for a discussion on this?
11:12:48 <oneswig> There's been some interesting talk recently about DDN Lustre and Kubernetes CSI
11:13:04 <oneswig> An improbable pairing that apparently works
11:17:09 <janders> oneswig not sure :(
11:17:28 <janders> regarding k8s + Lustre - not entirely surprised
11:18:04 <oneswig> Lustre's a user-space driver so may containerise well.
11:19:34 <oneswig> The question always arises, doing the development is one thing, supporting and sustaining it another matter altogether
11:23:01 <janders> agreed
11:23:33 <janders> but I think there is soemething in containers directly consuming filesystems, pending a reasonable security model
11:24:04 <janders> feels like one of the ways of the future (superfast object being another one)
11:25:09 <oneswig> I think it has good potential too.
11:26:20 <oneswig> janders: this might interest you: https://www.stackhpc.com/sc20-top500.html
11:27:12 <oneswig> We got a machine deployed with 1274 bare metal nodes using Ironic, and into the top 100 (just)
11:27:52 <janders> that is awesome! :)
11:28:04 <janders> can I re-post this on #openstack-ironic? :)
11:28:05 <oneswig> It's getting redeployed for production now.  There's going to be some mixed baremetal and virt, which will be implemented *somewhat* like SuperCloud
11:28:21 <oneswig> janders: of course :-)
11:28:26 <janders> ...and the idea lives on - fantastic!
11:28:42 <janders> I am very glad to hear this
11:28:54 <oneswig> The method isn't an exact copy of your approach, but hypervisors will exist in the overcloud Ironic.
11:30:42 <verdurin> Looks nice. Does the main text refer to the machine at the Other Place?
11:30:52 <verdurin> Not the UM6P one?
11:31:32 <oneswig> verdurin: They are somewhat similar and borrow from each other.
11:32:34 <oneswig> The telemetry graph, I don't think it says, is from a day of LINPACK benchmarking.  You can see the carbon footprint of HPC
11:42:16 <oneswig> I got the free pass to Supercomputing but must admit I've yet to use it.  Anyone followed the keynotes or other parts?
11:43:48 <verdurin> I watched a few bits last week, have lacked the time to look at anything this week.
11:48:21 <oneswig> alas a similar situation here.
11:48:32 <oneswig> Any other business to raise?
11:48:37 <janders> same here with Kubecon :(
11:48:54 <janders> I think we're good
11:48:59 <janders> it was great to chat! :)
11:49:22 <oneswig> Likewise, thanks janders verdurin
11:49:27 <verdurin> Yes, bye.
11:49:32 <oneswig> I will follow up with ideas on Lustre
11:49:46 <oneswig> until next time
