14:06:21 <zhipeng> shaohe_feng will sundar attend ?
14:06:50 <shaohe_feng> zhipeng, I do not think so
14:07:00 <zhipeng> on vacation ?
14:07:00 <shaohe_feng> he is on vocation.
14:07:02 <shaohe_feng> yes
14:07:12 <zhipeng> until when ?
14:07:25 <shaohe_feng> seems \7/25
14:08:11 <shaohe_feng> from July 10 night through July 25, coming back on 26th.
14:08:22 <zhipeng> lol
14:08:40 <Coco_Gao> long vacation.
14:08:48 <zhipeng> okey let's get into business
14:09:00 <zhipeng> #topic Rocky Development Update
14:09:05 <zhipeng> #link https://review.openstack.org/#/q/status:open+project:openstack/cyborg
14:09:12 <zhipeng> #topic os-acc design
14:09:33 <zhipeng> https://review.openstack.org/577438
14:09:56 <zhipeng> Li_Liu shaohe_feng is there any consensus converging on the current proposal ?
14:11:26 <Li_Liu> I don't have any further comments on that one
14:11:38 <zhipeng> meaning satisfied ?
14:11:45 <zhipeng> or still waiting for answers
14:11:47 <shaohe_feng> I really want to know the scope of the os-acc.
14:12:34 <shaohe_feng> will it cover the program and instance binding?
14:14:20 <shaohe_feng> we have not define the binding interface. The binding should pass hostname and instance uuid and request spec.
14:14:32 <zhipeng> Li_Liu wangzhh Coco-Gao what's your opinion
14:14:55 <wangzhh> I think so. os-acc call cyborg to program and bind.
14:15:36 <Li_Liu> it should be able to call the program API
14:16:04 <shaohe_feng> rest full API
14:16:15 <shaohe_feng> ?
14:16:22 <Li_Liu> but how it calls it is the problem here
14:16:23 <wangzhh> Not just restful api.
14:16:32 <Li_Liu> exactly
14:16:43 <Li_Liu> rest/rpc/something else?
14:17:14 <Li_Liu> for the moment, the most intuitive way is calling the REST API I am currently writing
14:17:35 <shaohe_feng> can program also call RPC?
14:17:46 <zhipeng> wangzhh how's the os-brick handling the attach ?
14:17:58 <Coco_Gao> wangzhh sundar suggest to use rpc call?
14:18:14 <wangzhh> I've talked to Sundar about it.  We agreed that os-acc should call not just api.
14:19:06 <wangzhh> In fact, call api only is another option.
14:19:38 <zhipeng> besides api what could it call ?
14:20:29 <Li_Liu> Maybe allowing os-acc directly call the vendor driver api is another option
14:20:53 <zhipeng> that would be the original design right ?
14:21:02 <zhipeng> contain it on the compute node level
14:21:08 <zhipeng> without any api interactions
14:21:19 <wangzhh> In some cases, we must call api. But sometimes, rpc call is a good code path, too.
14:21:33 <Coco_Gao> os-acc call cyborg-agent using rpc?
14:21:56 <wangzhh> CoCo: Yes
14:22:17 <wangzhh> The original design right.
14:23:01 <Coco_Gao> ok, when should we use rpc and when should we use api?
14:23:27 <wangzhh> Sorry, lost an "is".
14:24:41 <wangzhh> Attach, deatch use rpc.
14:26:44 <Li_Liu> zhipeng: "contain it on the compute node level". that should be the easiest way for now
14:27:00 <zhipeng> will attach/detach involving binding shaohe_feng mentioned ?
14:29:38 <xinran__> Binding is before attach I think？
14:30:08 <zhipeng> bind the vm instance with the acc instance ?
14:30:18 <zhipeng> do we have similar process in other module ?
14:31:09 <Li_Liu> the binding should be taken care of before the process get to the vendor driver
14:31:13 <wangzhh> Neutron
14:31:40 <zhipeng> i think there was a comment from Sundar states that it is kinda different for neutron
14:31:46 <zhipeng> the port binding
14:31:48 <wangzhh> Nova call neutron-agent directly to allocate port.
14:31:50 <zhipeng> and the acc binding
14:33:15 <zhipeng> okey let's arrange another ZOOM call for specificities
14:33:28 <zhipeng> the big problem here is about the os-acc scope, like shaohe said
14:33:37 <zhipeng> what we want it to be for Rocky release
14:33:46 <wangzhh> In my opinion, we can imply it as the design now.  For the api and os-acc are stable. We can refactor it if needed.
14:33:57 <zhipeng> bare minimum , or we want binding, programming in it as well
14:34:36 <zhipeng> we need to start implementation as soon as possible for sure
14:34:50 <Li_Liu> I agree with wangzhh, we should get the thing working first
14:35:03 <Li_Liu> ZOOM call would be great
14:35:24 <zhipeng> Li_Liu will it block FPGA programing if os-acc does not include program support ?
14:36:07 <Li_Liu> no it should not as my programming support is a stand alone feature
14:36:15 <Li_Liu> it does not depends on others
14:36:57 <zhipeng> okey then let's shoot for the minimum feature goal
14:37:26 <zhipeng> shall we have a ZOOM meeting say 10:00 am tmr ?
14:37:35 <zhipeng> discuss os-acc in detail ?
14:37:53 <Li_Liu> you mean china time?
14:38:07 <zhipeng> yes, 10:00pm for Toronto
14:38:14 <Li_Liu> should be fine
14:38:17 <zhipeng> about less than 12 hours later
14:38:22 <Li_Liu> up to you guys
14:38:33 <zhipeng> wangzhh shaohe_feng Coco-Gao okey ?
14:38:53 <wangzhh> I'm OK.
14:39:03 <Coco_Gao> ok
14:39:34 <zhipeng> ok then I assume shaohe is ok as well :)
14:39:37 <zhipeng> moving on
14:39:43 <zhipeng> #topic GPU driver
14:39:44 <sum12> could you guys post some notes about your discussion ?
14:39:53 <zhipeng> sum12 definitely
14:40:20 <zhipeng> wangzhh any timeline for the GPU driver ?
14:40:36 <zhipeng> #link https://review.openstack.org/574075
14:41:04 <wangzhh> I'll update the commit tmr.
14:41:23 <zhipeng> can you also reply to the NVIDIA guy ?
14:41:36 <zhipeng> i remember he asked about an introduction about the driver code
14:41:40 <zhipeng> in the email thread
14:41:44 <wangzhh> Of course. I have promised Mike.
14:42:13 <zhipeng> gr8t :)
14:42:16 <zhipeng> moving on
14:42:25 <zhipeng> #topic FPGA API
14:42:28 <Coco_Gao> I think Mike asked more than the driver code, but the cyborg related code as well.
14:42:39 <zhipeng> #link https://review.openstack.org/579315
14:42:48 <zhipeng> Li_Liu is this still premature ?
14:43:26 <wangzhh> Coco: Yes. I'll try my best to describe it.
14:44:07 <Li_Liu> zhipeng, it's not ready yet
14:44:26 <zhipeng> okey got it
14:44:40 <zhipeng> moving on to next
14:44:46 <zhipeng> #topic Quota support
14:44:50 <zhipeng> #link https://review.openstack.org/564968
14:44:59 <zhipeng> xinran___
14:45:55 <zhipeng> why is there a 16KiB file change in the patch ?
14:46:03 <zhipeng> the swp file
14:46:37 <wangzhh> haha. :)
14:47:01 <zhipeng> lol so weird
14:47:49 <zhipeng> xinran__ are you around ?
14:47:53 <shaohe_feng> http://docs.ocselected.org/openstack-manuals/kilo/networking-guide/content/logical-architecture.html
14:48:38 <shaohe_feng> #link https://docs.openstack.org/install-guide/get-started-logical-architecture.html
14:49:08 <wangzhh> https://review.openstack.org/#/c/580022/2/.gitignore This commit could resolve the swp file.
14:50:44 <xinran__> I’m here
14:50:59 <xinran__> Sorry for the swp file...
14:51:08 <xinran__> Haha
14:51:11 <zhipeng> no problem
14:51:30 <zhipeng> other than that, plz address Li Liu's commenty
14:51:37 <zhipeng> and let's move forward
14:51:43 <xinran__> OK
14:52:28 <zhipeng> okey i think we reviewed most of the important current available patches
14:52:59 <Li_Liu> zhipeng, what's the currently time line?
14:53:18 <zhipeng> shooting for code completion before RC freeze
14:53:53 <Li_Liu> ok
14:54:13 <Li_Liu> but the os-acc and nova interaction is still faaar behind..
14:55:28 <zhipeng> https://releases.openstack.org/rocky/schedule.html
14:55:39 <zhipeng> os-acc will miss the R release i'm fraid
14:55:44 <zhipeng> as non-client libraries
14:56:07 <zhipeng> but as long as we have code implementation, we could have docs guiding the user how to use it
14:56:19 <Li_Liu> ok
14:56:35 <zhipeng> the week of Aug 20 - Aug 24 is the RC deadline
14:56:48 <Li_Liu> I am just hoping we can make cyborg be in a usable state in R
14:56:54 <zhipeng> which gives us barely more than a month of time
14:57:01 <zhipeng> Li_Liu of course
14:57:34 <zhipeng> #topic Berlin Summit CFP
14:57:47 <Coco_Gao> since we will merge accelerator&deployable db table, should we modify the code after xinran's code being merged?
14:57:50 <zhipeng> Plz be aware that the Berlin Summit CFP ends on Jul 17th
14:58:08 <wangzhh> Zhipeng, Li_liu, if we can't merge os-acc in nova in time.  Can we offer the code as patch to user?
14:58:20 <zhipeng> wangzhh that was what I meant
14:58:31 <zhipeng> because the repo is aleady there, thx xinran__
14:58:40 <zhipeng> as long as we have workable code
14:58:49 <zhipeng> in or out of a release is not that big a deal
14:58:52 <Li_Liu> zhipeng, will you go to Berlin?
14:59:17 <zhipeng> yes definitely
14:59:22 <zhipeng> maybe will do a keynote
14:59:28 <zhipeng> with cyborg+AI
14:59:35 <zhipeng> but nothing settled yet :P
14:59:36 <Coco_Gao> that's great
14:59:44 <wangzhh> Wow~
15:00:10 <Li_Liu> nice
15:00:27 <zhipeng> a big maybe, let see how Mark Collier and others works out the arrangement
15:00:31 <zhipeng> maybe nothing
15:00:56 <zhipeng> plz remember submit topic for Berlin Summit
15:01:05 <zhipeng> ok see you guys tmr on ZOOM
15:01:10 <zhipeng> 10am Beijing time
15:01:17 <Coco_Gao> tomorrow?
15:01:17 <xinran__> Coco_Gao:  I think you can go ahead because quota support still need Oslo limit be ready
15:01:41 <zhipeng> yes tmr
15:02:02 <zhipeng> xinran__ let's discuss it tmr as well
15:02:31 <xinran__> OK
15:02:55 <zhipeng> thx everyone
