21:05:27 <martial__> #topic  Berlin SIG BoF - Call for lightning talks
21:06:19 <martial__> Come-thee, come-thee, the Scientific SIG-ness has an opening for its participants to discuss the latest and greatest and the barely working during its Lighting Talk session
21:06:54 <martial__> we welcome the courageous, the brave and the crazy on our podium
21:06:55 <janders> barely as in bare metal? :)
21:07:02 <oneswig> oh, too good.
21:07:14 <oneswig> I shall think up a topic now.
21:07:32 <oneswig> Aha, money for old rope - I'm presenting at Ceph day on the Monday before.  I can squeeze that into 3 minutes, sure
21:07:59 <martial__> be thee brave friend? be thee stupendous with knowledge to share? Well thee are perfect for us ... come and bedazzle
21:08:43 <oneswig> martial__: been at the communion wine again? :-)
21:08:43 <martial__> so ... add thy words to our pad of the ether and amaze the crowd
21:09:06 <martial__> (selling it :) )
21:09:11 <oneswig> Sold!
21:09:22 <trandles> martial__: when are you auditioning for a job at Medieval Times?  Just back from a stay at Excalibur in Vegas?
21:09:33 <martial__> :)
21:10:05 <martial__> so as the words above totally say in more words, come, be happy, present and ... profit
21:10:18 <trandles> Someone get in touch with Arkady.  Best talk prize this go should be a sword-in-the-stone model. ;)
21:10:40 <martial__> who in this crowd is going beyond Sir OneSwig
21:10:53 <oneswig> I am lost for words
21:11:53 <martial__> well as long as you host the Joust :)
21:12:03 <janders> I'm sure that we can quickly write a sword-extracting ansible module
21:12:11 <martial__> :)
21:12:12 <oneswig> martial__: I hope you'll keep this up for your video message to address the SIG meeting
21:12:35 <martial__> 4am my time? I will be just in the right state of sleep :)
21:13:11 <janders> time is relative and only a function of space
21:13:16 <oneswig> Are preparations going well for SC?
21:13:24 <martial__> but yes I am proposing to host a GTM for people who are interested to view the meetings remotely
21:13:32 <martial__> (and maybe record it?)
21:14:17 <martial__> so if you are interested in participating, add your name to
21:14:23 <martial__> #link https://wiki.openstack.org/wiki/Scientific_SIG#IRC_Meeting_October_30th_2018
21:14:32 <martial__> oops wait no
21:14:43 <martial__> #link https://etherpad.openstack.org/p/Berlin-Scientific-SIG-BoF
21:14:55 <martial__> ^ that one
21:15:14 <martial__> in truth that is the agenda I have for Today
21:15:40 <janders> in which case let me propose this agenda item:
21:15:45 <janders> IBM acquisition of Red Hat
21:15:49 <martial__> ouch
21:16:05 <oneswig> janders: anything to avoid repeating your excellent presentation!?
21:16:11 <janders> what are your thoughts on what this means to OpenStack and Ansible?
21:16:16 <martial__> tim, are you staying until the end? (have to leave in 15 minutes)
21:16:20 <oneswig> I see no harm for Ansible.
21:16:53 <janders> oneswig: I don't mind repeating if there is interest, but curious what people think
21:17:10 <oneswig> IBM's interest in OpenStack is not what it once was (true for many larger and more corpulent corporations)
21:17:49 <oneswig> But perhaps that is why they covet Red Hat, who have clearly made a stellar success from their contribution
21:18:22 <janders> what's your feel regarding RHAT being left alone as promised as opposed to IBM making attempts of tighter integration of the two organisations?
21:18:52 <oneswig> I think it looks bleak for Red Hat's business-centric offerings.
21:19:12 <oneswig> And I'm not sure I'd back GlusterFS against SpectrumScale
21:19:21 <janders> I clearly wouldn't :)
21:19:46 <janders> if Ceph+CephFS didn't kill Gluster, Spectrum might
21:19:48 <martial__> did not think of that I must say
21:19:55 <oneswig> I assume there will be ever closer union.  Perhaps a bit like Hong Kong and mainland China
21:20:12 <martial__> that said I truly saw this more as "we need cloud and open source" ...
21:20:38 <martial__> wait and see I guess
21:20:46 <oneswig> Who owns Pivotal (and RabbitMQ)?  Was that Dell?
21:21:06 <janders> what are your bets on Microsoft buying Canonical now? :)
21:21:21 <oneswig> I'll bet you 500 beers that doesn't happen
21:21:28 <oneswig> (very small ones)
21:21:33 <janders> :D
21:21:44 <martial__> ah yes since we are already in that ...
21:21:47 <martial__> #topic AOB
21:22:11 <oneswig> martial__: will you have a beer night at SC for the Scientific SIG?
21:22:24 <janders> oneswig: why do you think Micosoft's acquisition of Canonical is unlikely?
21:22:32 <trandles> martial__: I'm here
21:22:58 <martial__> I can try to see who is around indeed (will send an email to the ML)
21:23:18 <martial__> the SC18 counter dinner
21:23:26 <oneswig> janders: I am not sure what to expect nowadays, but still
21:23:41 <martial__> janders: what next Microsoft buying Github?
21:23:53 <trandles> ah, well, I'm only at SC18 from Monday night until early Wednesday morning (read: I'm only available on Tuesday for anything at SC18)
21:24:02 <janders> ..and Apple buying Microsoft? :)
21:24:11 <janders> ..and then Amazon will take over the main Linux distro
21:24:31 <martial__> oh boy, let's conclude being on the record :)
21:24:46 <martial__> any AOB to discuss?
21:24:55 <jmlowe> Hi everybody
21:25:02 <trandles> Denver 19 Summit
21:25:05 <oneswig> Hi jmlowe
21:25:14 <trandles> I see on the foundation page that it's April 29-May 2
21:25:18 <martial__> Hey Mike, welcome
21:25:38 <oneswig> Thanks trandles, noted
21:25:41 <trandles> FWIW - The Rockies are playing a baseball game on May 3.  I know it's the night after the summit ends, but I might try organizing a group to go.
21:25:59 <jmlowe> I'd be interested
21:26:17 <martial__> Stig, we are clearly on AOB, can you close? :)
21:26:31 <oneswig> martial__: I think so
21:26:37 <oneswig> bon voyage martial__
21:26:46 <martial__> thanks, gotta go pick up the younglings
21:26:57 <trandles> later all
21:26:59 <martial__> team, see some of you at SC18
21:27:03 <janders> see you guys
21:27:05 <trandles> jmlowe: interest recorded ;)
21:27:49 <oneswig> trandles: are you still here?
21:27:59 <trandles> I am
21:28:07 <oneswig> smashing
21:28:28 <trandles> pumpkins (is this word association? ;) )
21:28:37 <oneswig> trandles: jmlowe: did you see janders presentation from last week on mixing virt upon bare metal?
21:28:40 <oneswig> Highly recommended.
21:28:42 <trandles> oneswig: might want to endmeeting
21:28:52 <jmlowe> I didn't got a  link?
21:29:01 <trandles> I saw janders link in the minutes but didn't click yet
21:29:11 <oneswig> pumpkins - very topical. I ate an entire pumpkin pie when it became clear my family are not fans.
21:29:12 <janders> https://docs.google.com/presentation/d/1fh6ZOq3DO-4V880Bn7Vxfm5I1kH5b0xKXHBLW2-sJXs/edit#slide=id.p
21:29:31 <trandles> +1 pumpkin pies - what's not to like??
21:30:00 <jmlowe> Daylight savings ends this week for the US, makes participating a bit easier btw
21:30:22 <trandles> janders: thx for the link
21:30:25 <trandles> reading now
21:30:30 <jmlowe> for those of us in the eastern time zone
21:30:37 <oneswig> jmlowe: good to hear it, although in 2 weeks no doubt you'll have your hands full
21:30:43 <janders> no worries :)
21:31:11 <oneswig> janders: how close are you to production workloads at scale on this system?
21:31:54 <janders> we're ready for power-POC with users on but we're delaying this to focus on procurement
21:32:03 <janders> for full prod I'd like to do more work on resiliency and HA
21:32:31 <janders> we focused on capability first and we've got that and we're confident with that
21:33:00 <trandles> janders: we have a network stress test application (I think it's MPI-based) that we use for some early acceptance testing...if I can get my hands on it, would you be willing to give it a go on (Super)Cloud?
21:33:17 <janders> now we need to work on some implementation details that most people are not interested in
21:33:34 <janders> trandles: sure! jacob.anders@csiro.au
21:33:43 <oneswig> trandles: sounds like a quid pro quo arrangement there?
21:34:12 <trandles> janders: thanks, I'll get back to you
21:35:22 <oneswig> janders: what generation of IB was it?  100G?
21:35:29 <janders> FDR/56
21:36:05 <janders> but the final system will certainly have a newer interconnect :)
21:36:38 <janders> I do think we'll maintain significant investment in FDR - it's good enough for many things and there's potential of getting a fair bit of free FDR kit from other projects
21:37:47 <janders> we likely have some FDR14/40 in the mix too but it's transparent implementation wise so not sure what's the proportion
21:37:53 <oneswig> That 200G IB is taking a while to materialise
21:38:06 <janders> I meant FDR10/40 sorry
21:38:13 <janders> that's right!
21:38:32 <janders> I bet it's got something to do with PCIe4 taking sweet forever too
21:39:01 <janders> have you guys had a chance to do any testing on HDR/200?
21:39:15 <oneswig> not here
21:39:43 <janders> same here for now
21:40:50 <trandles> we're fully in OPA space on our latest machines, so no HDR here
21:41:07 <janders> from what I hear it should be very similar to drive to EDR as far as OpenStack is concerned, but I bet there'll be some catch somewhere :)
21:41:22 <janders> trandles: do you have any OpenStack on OPA?
21:41:42 <oneswig> I've been working on OPA and Ceph again - a last push to get it working well
21:42:09 <janders> OPA doesn't have virtual function support or fabric segmentation support, right?
21:42:18 <trandles> I do not have OpenStack on OPA :(
21:42:18 <oneswig> janders: you want to speak to rbudden on OPA+OpenStack
21:42:32 <trandles> AFAIK OPA doesn't support SR-IOV, no
21:42:38 <oneswig> I believe you're right
21:42:43 <trandles> but +1 what oneswig says
21:43:10 <trandles> PSC's Bridges cluster is OPA, albeit a very early OPA
21:44:42 <janders> I don't believe I've met rbudden yet
21:45:20 <jmlowe> janders: headed to sc'18?
21:45:29 <janders> no, OS Berlin
21:45:34 <trandles> janders: https://github.com/jlothian/sysconfidence
21:45:38 <trandles> that's the benchmark
21:46:04 <oneswig> thanks trandles, might bookmark that myself
21:46:26 <janders> thanks! :)
21:47:14 <oneswig> OK do we have any more AOB?
21:47:25 <trandles> I believe it was written by Oak Ridge originally.  Meant to stress the fabric on a traditional cluster.  It would be good to see what folks are getting on our scientific clouds, especially if you can test baremetal and from within VMs.
21:48:01 <oneswig> trandles: what does a good result look like?
21:48:53 <trandles> oneswig: I'll poke at our local expert and get back to you.  He fired off the link quickly and said "talk later."
21:49:14 <janders> I'll probably need to audit the HCAs switches and cables to make sure there's no FDR40 to get a good number
21:49:25 <oneswig> OK thanks trandles.
21:49:29 <janders> for multinode workloads on IB any inconsistencies are asking for trouble
21:50:04 <trandles> it's focused on latency, so in theory we should know lowest from the vendor
21:51:03 <oneswig> Shall we close the meeting?  Any more to add?
21:51:14 <trandles> none from me, thanks everyone
21:51:40 <janders> I'm good - thanks guys!
21:51:54 <oneswig> OK, it's a wrap...
