| 15:04:22 | shaohe_feng_ | what does Howard mean? | |
| 15:05:42 | zhipeng | my alias lol | |
| 15:06:19 | shaohe_feng_ | got it | |
| 15:07:05 | shaohe_feng_ | Any info? | |
| 15:07:19 | shaohe_feng_ | are we waiting for others? | |
| 15:07:49 | zhipeng | that is the cmd that will record your name in the minutes | |
| 15:08:03 | zhipeng | we are waiting for justin and crushil | |
| 15:08:22 | crushil | zhipeng, I am here | |
| 15:08:28 | crushil | Just in another meeting | |
| 15:09:07 | crushil | #info Rushil | |
| 15:09:16 | zhipeng | no problem :) | |
| 15:09:19 | crushil | zhipeng, Justin is on vacation till this friday | |
| 15:09:28 | zhipeng | ah okey | |
| 15:09:34 | zhipeng | then we can just start | |
| 15:09:45 | zhipeng | he could catch up later with the minutes | |
| 15:11:27 | shaohe_feng_ | any introduce for each? | |
| 15:11:27 | zhipeng | #topic Sydney Summit slide review | |
| 15:11:45 | zhipeng | crushil is our core reviewer from Lenovo :) | |
| 15:11:55 | zhipeng | shaohe_feng_ is from Intel | |
| 15:12:13 | shaohe_feng_ | crushil: hello, I'm shaohe feng | |
| 15:12:29 | zhuli | Sorry guys, it’s been a long time since we meet last time, unfortunately ,because I work very late today and I am driving home now, couldn’t pay attention to this meeting, so I will read the log history later and send some emails if needed | |
| 15:13:02 | zhipeng | zhuli safe driving ! | |
| 15:13:03 | shaohe_feng_ | crushil: from intel. focus on intel's accelerator | |
| 15:13:30 | zhipeng | hope you are using audio to text ML converter zhuli :P | |
| 15:13:40 | zhipeng | anyways back to the topic | |
| 15:13:49 | zhipeng | we have one lightening talk at Sydney Summit | |
| 15:14:23 | zhipeng | I have sent a simple slide I prepared to ttk[m] and crushil based upon our report to TC back in Denver | |
| 15:14:49 | zhipeng | so I might add a few today or tmr, but I think it should be ok now content wise for the lightening talk | |
| 15:15:19 | crushil | I made some changes | |
| 15:15:45 | crushil | And I am talking about it to my coworker who will present for us at Sydney | |
| 15:16:32 | zhipeng | ok gr8t | |
| 15:16:41 | zhipeng | i think we should have few problem with the slide | |
| 15:17:03 | zhipeng | and we could make the slide publicly available after the summit session | |
| 15:17:08 | crushil | Ya | |
| 15:18:49 | zhipeng | okey let's move onto the important topic today | |
| 15:19:02 | zhipeng | #topic Placement-Cyborg Interaction Discussion | |
| 15:19:34 | zhipeng | So I have been studying the Placement/Resource Provider/Trait stuff last week | |
| 15:19:45 | zhipeng | and attended the nova-ironic trait meeting yesterday | |
| 15:19:57 | zhipeng | so let me first send out some useful links here | |
| 15:20:18 | zhipeng | #link https://github.com/jaypipes/articles/blob/master/openstack/placement-queens-update.md | |
| 15:20:46 | zhipeng | #info Jay Pipe's writeup on Placement | |
| 15:20:52 | zhipeng | this is as the best as you could get | |
| 15:21:12 | zhipeng | and there are two specs that will be very useful to us, from Ironic | |
| 15:21:23 | zhipeng | #link http://specs.openstack.org/openstack/nova-specs/specs/queens/approved/ironic-driver-traits.html | |
| 15:21:40 | zhipeng | #link https://review.openstack.org/#/c/504531/ | |
| 15:22:17 | zhipeng | #info first one is about Ironic report/accept trait with Nova, second one is about trait config in Ironic | |
| 15:22:45 | zhipeng | ok there is another spec that will help our modeling, is the vGPU spec from jianghua | |
| 15:23:00 | zhipeng | #link http://specs.openstack.org/openstack/nova-specs/specs/queens/approved/virt-add-support-for-vgpu.html | |
| 15:23:21 | zhipeng | and even more interestingly | |
| 15:23:32 | zhipeng | we could also learn something from the kubernetes discussion | |
| 15:23:35 | zhipeng | #link https://github.com/kubernetes/community/pull/782 | |
| 15:23:48 | zhipeng | #info k8s discussion on resource class for accelerators | |
| 15:24:36 | zhipeng | well based upon all the readings i did via the above mentioned links | |
| 15:25:06 | zhipeng | I think there several points we need to consider when we modeling cyborg maneged resources | |
| 15:25:43 | zhipeng | #info 1. We need to define CUSTOM_ traits for sure, but also some additions to os-trait lib on FPGA if there are any | |
| 15:26:41 | zhipeng | #info 2. other than the reporting from cyborg-agent to the Placement API, we need (a) the driver also support trait api and (b) cyborg-api support trait | |
| 15:27:09 | crushil | zhipeng, Ya, I have been following the traits discussion on the Ironic end too. So, I might have some inputs once there is a spec up on our end | |
| 15:27:44 | zhipeng | #info 3. There is a caveat for Cyborg on resource provider modeling for accelerators which is we need to find a way to model different types of accelerators in a unified way | |
| 15:29:17 | zhipeng | #info 3a. Traits and resource class are used to define qualitive and quantative side of resource, however we might need a third kind to descirbe accelerators, because only using traits and ResourceClass means we will have a lot them for different accelerators | |
| 15:30:35 | zhipeng | #info 3b. We might need to consider using something like capability to describe the accelerator resource. For example FPGA and GPU both could be used for ML, a user might just want a VM to run a ML workload with the help of an attached accelerator | |
| 15:31:29 | zhipeng | #info 3c. This means we need to enable user to be able to select one capable resource instead of identifing very specifically which resource they want | |
| 15:31:43 | zhipeng | ok that is the end of my monologue lol | |
| 15:31:49 | zhipeng | any thoughts ? | |
| 15:37:32 | shaohe_feng_ | need time to reading the link, too many info. | |
| 15:38:11 | zhipeng | ya , any thoughts on my comments above ? besides the links :P | |
| 15:43:05 | crushil | I will chime in once we have specs in our backlog | |
| 15:43:36 | crushil | I have some thoughts about the way we should be implementing traits on our end and handing them over to Nova | |
| 15:44:22 | zhipeng | crushil that brings mine proposals actually | |
| 15:44:23 | crushil | And that will alter the implementation of the generic driver as well which I am working on currently | |
| 15:44:36 | zhipeng | i think besides justin's general spec | |
| 15:44:46 | zhipeng | we will need one on the driver side and one on the api side | |
| 15:45:06 | zhipeng | would you like to lead on the driver trait spec ? | |
| 15:45:11 | crushil | Sure | |
| 15:45:37 | crushil | When is the stable Queens release date? | |
| 15:45:40 | zhipeng | zhuli and I will work on the api side | |
| 15:45:54 | zhipeng | crushil I need to double check on that | |
| 15:46:21 | crushil | I think we need to be reasonable with the amount of work we promise | |
| 15:46:30 | crushil | I would hate to overpromise and underdeliver | |
| 15:46:37 | zhipeng | #action crushil to work on a new spec on cyborg driver trait support, and zhipeng will work on a new spec on api trait extention | |
| 15:46:43 | zhipeng | crushil that is for sure | |
| 15:48:15 | zhipeng | and on that note, let's also start simple | |
| 15:48:32 | zhipeng | we could cover very basic trait descriptions for Queens | |
| 15:48:57 | zhipeng | meaning for example not necessarily model FPGA resources in a Tree structure in full | |
| 15:49:11 | zhipeng | let's deliver something basic in Queens | |
| 15:49:42 | crushil | zhipeng, Exactly with at least a shim that vendors can build upon | |
| 15:49:56 | zhipeng | crushil +1 | |
| 15:50:13 | zhipeng | okey any more comments on this topic ? | |
| 15:50:38 | zhipeng | folks you are more than welcomed to provide further feedback on mailing list later on | |
| 15:50:53 | crushil | zhipeng, We need to have something like a midcycle to go over things that need work on | |
| 15:51:10 | zhipeng | that is what I think | |
| 15:51:20 | zhipeng | maybe a video conf meeting for like 2-3 hours ? | |
| 15:51:24 | crushil | Ya | |
| 15:51:27 | zhipeng | maybe the week of Sydney Summit ? | |
| 15:51:34 | zhipeng | since all of us will not be there lol | |
| 15:51:38 | crushil | lol | |
| 15:51:47 | zhipeng | let's do something useful instead | |
| 15:51:48 | crushil | Or we can do that monthly | |
| 15:51:58 | zhipeng | of cource that'd be great | |
| 15:52:10 | crushil | Justin and I can be in the same room | |
| 15:52:59 | zhipeng | lol don't eat ice cream in front of me | |
