09:01:14 <oneswig> hello world ...
09:01:16 <priteau> Good morning!
09:01:23 <oneswig> Hi priteau!
09:01:50 <oneswig> People really are winding down for Christmas, I guess :-)
09:02:22 <oneswig> #link agenda for today is https://wiki.openstack.org/wiki/Scientific_working_group#IRC_Meeting_December_21st_2016
09:02:56 <oneswig> I am at Bristol Parkway and have a train to catch in about 30 minutes, so need to give half apologies myself!
09:03:08 <b1airo> o/
09:03:09 <oneswig> #chair b1airo
09:03:10 <openstack> Current chairs: b1airo oneswig
09:03:16 <oneswig> Hi b1airo
09:03:37 <oneswig> Just us and priteau so far...
09:03:44 <b1airo> bit tardy sorry - at the beach with the family and the usual schedule has gone out the window
09:03:47 <priteau> Evening blair
09:03:56 <oneswig> You're at the beach right now?
09:03:58 <priteau> Lucky you!
09:04:00 <b1airo> hi priteau, oneswig
09:04:07 <b1airo> yep!
09:04:16 <oneswig> That's so Australian
09:04:21 <oneswig> respect :-)
09:04:23 <b1airo> well, it's 80m or so away
09:04:43 <b1airo> i'll grill you a prawn
09:04:44 <daveholland> I'm sure you could get wifi that far
09:04:51 <oneswig> Hi daveholland
09:05:25 <daveholland> hi, only grey skies here
09:05:35 <oneswig> #topic Events and CFPs
09:05:47 <b1airo> daveholland, with the property values down here i'm sure you can get fibre if you want to pay!
09:06:06 <oneswig> Does everyone have the agenda with the links in it?
09:06:41 <oneswig> 3 events arrived in the in-tray this week - OpenStack Boston, Red Hat (also in Boston) and OpenFabrics Summit (in Austin)
09:06:47 <verdurin> Morning.
09:06:53 <oneswig> Hi verdurin
09:06:57 <oneswig> just getting going
09:07:00 <b1airo> i'll be back in 5, last administration of dr suess for the day is required...
09:07:12 <oneswig> to thing 1 or thing 2?
09:08:03 <oneswig> The OpenFabrics workshop looked interesting because virtualisation and OFA is specifically called out as a topic for discussion
09:08:31 <oneswig> And I believe it coincides with a Dell community event, for the Dell customers out there...
09:08:49 <verdurin> oneswig: Is the Red Hat event their usual Summit?
09:09:11 <oneswig> I think so.  Not been - have you?
09:09:27 <verdurin> No.
09:09:48 <priteau> first time it is colocated with the OpenStack Summit though?
09:10:30 <oneswig> Presumably not a coincidence... good move on their part.  Ironically I may be able to attend the RH summit but not the OpenStack one
09:11:02 <oneswig> Any other incoming events to be aware of?
09:11:44 <verdurin> FOSDEM?
09:11:55 <oneswig> Aha, good point, glad you mentioned it!
09:12:29 <verdurin> There's usually quite a lot of OpenStack-related stuff
09:12:33 <oneswig> As it happens (clueless me) one of my team has a paper accepted at the postgres conference coincident with FOSDEM - on monitoring with Monasca and postgres
09:13:42 <oneswig> OK lets move on
09:13:51 <oneswig> #topic GPUs and virtualisation
09:14:09 <oneswig> #link heres what was discussed last week http://eavesdrop.openstack.org/meetings/scientific_wg/2016/scientific_wg.2016-12-13-21.02.log.html
09:15:15 <oneswig> I think b1airo was talking about summarising in an etherpad
09:15:23 <b1airo> back! (oneswig: one fish, two fish ... - delivered to thing 1)
09:15:31 <oneswig> Unfortunately powerd I believe is in India
09:15:47 <oneswig> aha - any luck on that etherpad b1airo?
09:15:52 <b1airo> india? for work?
09:16:05 <oneswig> yes - conference - Indian SC (can't remember the name)
09:16:17 <b1airo> yeah let me find it again, had to kill my browser earlier...
09:21:06 <b1airo> oh have we lost oneswig ?
09:21:20 <oneswig> ah, still here, but about to head off - waiting for a train
09:22:41 <b1airo> looks like the channel topic changed, perhaps meetbot has headed off for xmas??
09:23:14 <oneswig> good point
09:23:21 <oneswig> #topic GPUs and virtualisation
09:23:30 <oneswig> any luck b1airo?
09:23:58 <b1airo> #link: https://etherpad.openstack.org/p/scientific-wg-gpu-config-guide
09:25:37 <oneswig> Thanks b1airo looks handy, will study
09:25:51 <b1airo> it's very much still WIP
09:26:02 <oneswig> why blacklist nouveau?
09:26:06 <b1airo> i only managed 5 mins earlier
09:26:28 <oneswig> not familiar with it...
09:27:02 <b1airo> if nouveau (or anything else, e.g., nvidia drivers) bind to the device in the hypervisor then passthrough will appear to work but the device will not work in the guest
09:27:07 <oneswig> Do you use the same trick with glance image attributes or is it tied to flavors and host aggregates?
09:27:41 <b1airo> nouveau is an "Accelerated Open Source driver for nVidia cards"
09:28:00 <oneswig> I'm out of time - have to catch my train - apologies
09:28:02 <b1airo> flavors and aggregates
09:28:20 <b1airo> no worries oneswig
09:28:26 <oneswig> thanks all, have a good Christmas - barbecued or not!
09:28:26 <b1airo> merry xmas, happy new year!
09:29:23 <b1airo> anyone else still paying attention? we figured things would be pretty quiet to-day/night
09:29:34 <priteau> Happy holidays onovy
09:29:43 <priteau> Oops, too late
09:29:56 <b1airo> :-)
09:30:43 <priteau> b1airo: I will review your etherpad to check how the scheduler could be configured to allow additional instances to use CPU resources
09:32:08 <priteau> but nothing else to contribute on the topic right nowo
09:32:43 <b1airo> priteau, great - i haven't really added anything on that yet, might be better to wait until the new year when the content settles a bit
09:32:51 <b1airo> i think you already understand the problem though
09:34:01 <priteau> I see you've got some scheduler details in there already (PciPassthroughFilter)
09:34:37 <verdurin> I'm still here, but only just back from holiday, so not much new to add
09:35:49 <b1airo> thanks verdurin
09:36:23 <b1airo> what do folks think would be useful in terms of docs re. GPUs in/with OpenStack ?
09:37:10 <priteau> Are there existing docs covering GPUs specifically already, or is it only generally about PCI passthrough?
09:38:16 <b1airo> just PCI passthrough AFAIK
09:38:20 <verdurin> b1airo: we need docs from both operators' and users' points of view (maybe stating the obvious)
09:38:34 <b1airo> from there you're into blogs (if lucky) and list posts
09:39:17 <b1airo> verdurin, interesting - i hadn't really thought about specific user docs before
09:40:55 <verdurin> b1airo: might not actually be necessary, but I think a full description of how to run a GPU application on OpenStack would be worthwhile
09:40:56 <priteau> yeah a full guide with usage example would be helpful
09:41:05 <verdurin> priteau: exactly
09:44:13 <b1airo> i'm sure you're right, and it probably fits in nicely with the GPU compute and graphics acceleration possibilities with e.g. PCI passthrough
09:45:07 <b1airo> #topic AOB (any other business)
09:45:56 <b1airo> any other news or shall we wrap it up for now?
09:46:07 <verdurin> Not from me.
09:46:26 <b1airo> oneswig, martial and i need to catch up on boston organisation and report back to the group
09:46:41 <priteau> Nothing from me
09:46:44 <b1airo> we need to be proposing sessions very soon
09:49:55 <b1airo> alright, may as well put this to bed (and myself :-) )
