| #openstack-cyborg - 2018-04-11 | |||
| 14:52:34 | zhipeng | Coco we want to be able to do that | |
| 14:52:44 | zhipeng | and the os-acc will be part of the solution to make that happen | |
| 14:53:50 | zhipeng | back to topic | |
| 14:53:57 | kosamara | Not using launchpad for anything anymore? | |
| 14:54:14 | zhipeng | kosamara yes that is correct | |
| 14:54:29 | zhipeng | from now on, all the bug report, blueprint and so forth | |
| 14:54:35 | zhipeng | plz submit it onto storyboard | |
| 14:55:08 | zhipeng | #link https://storyboard.openstack.org/#!/project_group/77 | |
| 14:56:23 | zhipeng | okey | |
| 14:56:27 | zhipeng | #topic AoB | |
| 14:56:41 | zhipeng | any other business we want to discuss ? | |
| 14:56:44 | kosamara | I checked the vGPU spec | |
| 14:56:53 | zhipeng | kosamara plz continue | |
| 14:57:11 | kosamara | Comparing it with https://etherpad.openstack.org/p/Cyborg-Nova-Multifunction | |
| 14:57:45 | kosamara | it is basically implementing the D2 case in nova. | |
| 14:58:01 | NokMikeR | aob: an update or documentation on the install of cyborg with devstack would be great to see. | |
| 14:58:07 | zhipeng | but i think they were not able to actually fully do the D2 case right ? | |
| 14:58:27 | zhipeng | NokMikeR yes that would be part of the doc subteam's priority :) | |
| 14:58:47 | kosamara | Do you mean something specific out of D2? | |
| 14:59:19 | zhipeng | kosamara yes like Alex Xu commented | |
| 14:59:25 | NokMikeR | or a script that magically installs it is equally welcome. | |
| 14:59:37 | zhipeng | NokMikeR duly noted :) | |
| 14:59:43 | NokMikeR | lol | |
| 15:00:08 | kosamara | Yes, in their proposal it's a static configuration. | |
| 15:00:23 | zhipeng | yep | |
| 15:00:41 | kosamara | Each compute node needs to specify a mapping between gpu/vgpu_profile in a config file. | |
| 15:01:26 | kosamara | But I understood this static case to be the difference between D2 and B2 (orchestration). | |
| 15:02:58 | zhipeng | yes basically | |
| 15:04:24 | zhipeng | kosamara do you think if it is possible to improve the static configuration ? | |
| 15:05:50 | zhipeng | i mean in cyborg | |
| 15:06:08 | kosamara | The difference that I see between their proposal and Sundar's is that they are based on a static config, while Sundar relies on Placement traits. | |
| 15:06:56 | zhipeng | Sundar's proposal will need something like preferred trait | |
| 15:07:06 | kosamara | That means that Cyborg could implement Sundar's proposal as an alternative to the nova proposal, supporting a slightly different use case. | |
| 15:07:08 | kosamara | Yes. | |
| 15:07:20 | edleafe | Preferred traits are a long way off in Placement | |
| 15:07:32 | zhipeng | edleafe exactly | |
| 15:07:49 | kosamara | But D1/2 doesn't need preferred traits necessarily | |
| 15:08:31 | zhipeng | kosamara any chance you could write down some of your thoughts on this matter ? | |
| 15:08:41 | zhipeng | I think this could also be good to PoC :P | |
| 15:09:18 | kosamara | The flavor could require a particular vgpu profile as a trait, and then, as Sundar's proposal goes, Cyborg removes the incompatible traits from the resource provider that was picked by nova's scheduler. | |
| 15:10:31 | kosamara | Well a PoC is a bigger discussion. I'll start actually playing with vGPUs next week. RHEL 7.5 introduces support in kvm. | |
| 15:10:53 | zhipeng | sounds great :) | |
| 15:11:07 | kosamara | Initially I want to try out the nova proposal, and after that I can experiment with something else. | |
| 15:11:46 | kosamara | Does that fit with the rocky schedule? | |
| 15:11:57 | zhipeng | kosamara I think so | |
| 15:12:50 | Coco | Kosamara, we are doing the same thing now... | |
| 15:12:54 | kosamara | OK. So for a PoC we can talk again in ~10 days. I'll write some of these on Sundar's etherpad. Did you mean to write them somewhere else too? | |
| 15:13:15 | zhipeng | kosamara actually would be great to have an independant spec | |
| 15:13:15 | kosamara | Coco you mean trying vGPU with RHEL 7.5 | |
| 15:13:18 | kosamara | ? | |
| 15:16:05 | kosamara | I don't have any full-scale alternative proposal, I just compared nova's proposal with Sundar's. What would you expect in an independent spec? | |
| 15:16:39 | zhipeng | for example on the D2 case , or vGPU, what we could offer differently | |
| 15:16:48 | zhipeng | it does not need to be a full scale one | |
| 15:17:01 | zhipeng | since we will rely on Jianghua's spec as well | |
| 15:18:37 | kosamara | I think that Cyborg doesn't need to do 2 things for D2. The alternative to Sundar's is the nova spec (jianghua), which doesn't need cyborg. Cyborg adds the interplay with the extra Placement traits, which is nice for a little extra flex in D2. | |
| 15:20:07 | zhipeng | kosamara agree, what I meant is the overall vGPU data model could still follow Jianghua's, cyborg's own extra twist might come from your spec :) | |
| 15:20:45 | kosamara | ok... | |
| 15:20:59 | zhipeng | anyways, if you got the bandwidth :) | |
| 15:21:13 | zhipeng | it is not an imposition by any means :) | |
| 15:21:33 | kosamara | It's just that I'm a bit confused, not a lack of will :) Once I get to it, I'll drop you an email to discuss. | |
| 15:22:24 | zhipeng | haha sounds good :) After Sundar update the spec I think we could make it more clearer | |
| 15:23:22 | zhipeng | so if there is nothing more to discuss | |
| 15:23:28 | zhipeng | we could conclude the meeting now :) | |
| 15:24:00 | NokMikeR | nothing more here, thanks Howard/all. | |
| 15:24:04 | kosamara | nor here | |
| 15:24:29 | kosamara | sorry, just an update | |
| 15:24:34 | kosamara | Does devstack build now? | |
| 15:25:09 | zhipeng | yes i think so | |
| 15:25:28 | zhipeng | but it took a lot time I think | |
| 15:25:50 | kosamara | I'll try again then. Cool! | |
| 15:25:52 | zhipeng | once we have the CLI up it will be definitely more easier to play around instead of curl it lol | |
| 15:26:11 | zhipeng | kosamara if you run into any problem, storyboard or just yell it on irc :P | |
| 15:26:31 | kosamara | ok | |
| 15:27:08 | zhipeng | okey then folks, meeting adjourned | |

| 09:33:31 | openstackgerrit | Sundar Nadathur proposed openstack/cyborg master: Specification for Cyborg Agent-Driver API. https://review.openstack.org/561849 | |
| 09:38:04 | kosamara | Hi! I was trying cyborg in devstack again. At some point devstack is checking if every service is running and 2 things related to cyborg occur: | |
| 09:38:24 | kosamara | 1. expects a devstack@cyborg service, which it doesn't find | |
| 09:38:35 | kosamara | 2. devstack@cyborg-api has failed | |
| 09:38:53 | kosamara | #2 causes stack.sh to fail. | |
| 09:39:06 | kosamara | Does anyone have any insight? Pastebin: http://paste.openstack.org/show/ym8eEtMcHQjEWeLSkT0F/ | |
| 16:06:52 | zhipengh[m] | kosamara will pass along this to our Intel dev who has been helping debugging | |
| 16:07:16 | zhipengh[m] | Can you also submit a storyboard ticket ? | |
| 17:20:00 | kosamara | I also had some other problems with my devstack, which may or may not be cyborg-related :) I'll check tomorrow if I can replicate and then make a ticket. | |
