15:35:29 jkilpatr if we have enough 30 minute meetings we might be able to get our average down to an hour
15:35:34 jkilpatr by sometime in 2020
15:35:39 crushil jkilpatr, lol
15:35:40 zhipeng hahaha
15:35:54 crushil Btw I don't see the CFP on the ML zhipeng
15:36:08 crushil Btw I don't see it?
15:36:16 zhipeng I think I saw it sometimes ago
15:36:27 zhipeng will dig again and fwd to you guys
15:38:07 NokMikeR bye all
#openstack-cyborg - 2017-06-22
19:59:54 jkilpatr ok got config loading working and message passing working, next is rpc then these stubs are workable and should be merged so that we can work on a more integrated system

14:59:52 ttk2[m] Morning everyone.
15:02:04 zhipeng hey
15:05:49 zhipeng anyone else is here ?
15:13:59 openstack Meeting started Wed Jun 28 15:13:59 2017 UTC and is due to finish in 60 minutes. The chair is zhipeng. Information about MeetBot at http://wiki.debian.org/MeetBot.

15:14:03 openstack The meeting name has been set to 'openstack_cyborg'
15:14:33 zhipeng #topic Roll Call
15:14:54 NokMikeR #info Michael Rooke, Nokia
15:15:03 zhipeng #info Howard Huang
15:16:16 NokMikeR Must be summer :)
15:16:37 ttk2[m] #info Justin Kilpatrick, RedHat
15:16:43 ttk2[m] Sorry on a plane today.
15:16:57 zhipeng wow, still wifi ?
15:17:17 ttk2[m] Just landed.
15:17:44 zhipeng you work too hard :)
15:18:03 zhipeng #topic development progress
15:18:06 ttk2[m] Anyways I'd like to get that accelerator object stub merged so that I can start setting up the db components of the conductor. Messaging and rpc is working.
15:18:27 ttk2[m] The agent needs the dummy driver merged at least so that I can play around with integrating those two.
15:19:05 ttk2[m] Oh also I figured out the config module it loads transport urls and works in a real cloud env.
15:19:16 zhipeng crushil how's the driver patch going ?
15:19:32 zhipeng ttk2[m] config module ?
15:20:02 ttk2[m] Oslo config.
15:20:22 zhipeng okey
15:21:22 ttk2[m] Essentially I have all the basics worked out except the db so all the various components can talk to each other after that it's just a matter of writing business logic.
15:28:42 zhipeng ttk2[m] so looking at the conductor patch
15:28:47 zhipeng #link https://review.openstack.org/#/c/472662/
15:29:10 zhipeng I think except for a need to modify the patch title, it looks good for me to merge
15:30:01 zhipeng also the api spec could be merged at this point I guess
15:30:06 zhipeng #link https://review.openstack.org/445814
15:34:25 ttk2[m] API spec is good. And I'll get the db stuff into the conductor and then mark it as ready.
15:34:38 zhipeng cool
15:35:18 NokMikeR does the api cover listing an application running on the accelerator?
15:36:05 zhipeng we list accelerators, but i doubt we will list applications
15:36:12 zhipeng could you give a use case on that ?
15:36:50 NokMikeR GPU has a running application, you list the GPU to see if its 100% free, then discover its not, hence skip to the next one.
15:37:12 NokMikeR thats more fine grained than simply discovering / listing the accelerator itself.
15:37:23 ttk2[m] isn't that the same as listing usage?
15:37:43 ttk2[m] I'm planning on usage metric collection but I'm not sure if/how we expose that to the api instead of just the operator/internally
15:38:39 zhipeng i think we could definitely have that metric for the scheduler to use, but it might be just used internally
15:38:57 zhipeng and it would be difficult to model it in the resource provider, because it is dynamic
15:39:28 NokMikeR so operations like deleting an accelerator only occur when there is no running applications (=anything left) on the accelerator?
15:40:57 zhipeng i think it would be up to the users to make that judgement (check if nothing left running)
15:41:07 ttk2[m] that's easy enough to do as we have to control scheduling based on usage anyways
15:41:15 zhipeng cyborg will just receive a request to detach the accelerator for whatever purpose
15:41:22 NokMikeR ok
15:41:33 ttk2[m] on the ohter hand it would be a pretty bad user experience if an idling VM kept the accelerator from being changed.
15:42:07 NokMikeR or updated with something else since theres a left over app using resources that should be allocated for the new app etc.
15:42:37 NokMikeR maybe these are issues outside of cyborg, not sure.
15:51:42 ttk2[m] so managing instances attached to the accelerators is only partly cyborgs job
15:52:54 ttk2[m] I mean we'll list instances that are attached or running on various accelerators, but deciding if the work being done is useful is out of scope. And in the case of shared accelerators we're going to need to rely on them being able to print out who is doing what since there's probably a scheduler running below us for that.
15:55:02 zhipeng a sched running below us ?
15:58:39 ttk2[m] zhipeng: like if we had gpu virtualization and three vm's sharing a gpu
15:59:38 ttk2[m] there's a scheduler at the driver level taking workloads from the 3 virutal gpu's and muxing them into the real hardware. We may be able to see how much the actual hardware is utilized, but unless the driver tells us which vm is using what percentage of the total resources we're in the dark other than "these vm's are hooked up to this physical gpu"
16:06:08 zhipeng agree
16:06:31 zhipeng so many of this kind of scheduling will happen under the hood for cyborg
16:06:46 zhipeng unless the driver is able to report to cyborg

#openstack-cyborg - 2017-07-05
14:51:48 crushil_ So, no meeting today?
14:52:03 crushil_ Still working on the patches on my end
14:54:24 zhipeng yep, just in case folks still on vacation
14:54:42 zhipeng crushil_ if you could help on merge the api spec that'd be great :)
14:54:53 crushil_ zhipeng Already did
14:55:00 zhipeng oh thanks
14:55:11 crushil_ I have been on vacation for like more than a week and I'm coming back on 17th
14:55:28 crushil_ Still trying to get the patches done before I come back though
14:55:39 zhipeng crushil_ thanks a lot man :)
14:55:45 crushil_ zhipeng np
17:53:53 ttk2[m] my patches are in a pretty good state, so I'd like to see them land and then work on more stuff after than rip them up to add new features and hold off merging them for another few weeks
#openstack-cyborg - 2017-07-06
00:05:50 zhipengh[m] No problem
