| *** vrv_ has joined #openstack-cyborg | 14:06 | |
| zhipeng | so the deadline we are facing this week | 14:06 |
| zhipeng | is the client lib deadline | 14:06 |
| seungwook | Ho vrv | 14:06 |
| zhipeng | shaohe_feng how's the client side prepared ? Could we make it on time ? | 14:07 |
| shaohe_feng | zhipeng, which more features should we add for the client? | 14:08 |
| shaohe_feng | zhipeng, allocation? | 14:08 |
| zhipeng | could we do basic CRUD ? | 14:08 |
| shaohe_feng | zhipeng, unallocation? | 14:09 |
| Li_Liu | Does fpga program count? | 14:09 |
| Li_Liu | the program api should be ready this week | 14:09 |
| shaohe_feng | zhipeng, we can only list accelerators | 14:09 |
| Li_Liu | but calling the client part I am not sure | 14:10 |
| zhipeng | i don't think we could have programming in client on time | 14:10 |
| zhipeng | shaohe_feng, once coco and zhenghao's patch in | 14:10 |
| Li_Liu | ok, as least the api part | 14:10 |
| zhipeng | could we quickly add allocation and unallocation ? | 14:10 |
| xinran__ | hi seungwook welcome | 14:10 |
| zhipeng | in the most simple form, add to the db, remove from db | 14:10 |
| shaohe_feng | zhipeng, if we want to let nova call cyborg. we do not need CRUD for accelerators. we need CRUD for deployables. | 14:11 |
| Li_Liu | according to the discussion in here: https://etherpad.openstack.org/p/cyborg-rocky-development | 14:11 |
| seungwook | Thank xinran | 14:11 |
| shaohe_feng | we can use the current PATCH deployable for allocation and unallocation | 14:12 |
| shaohe_feng | but I do not think this is a good ideas. | 14:12 |
| shaohe_feng | also do we need batch allocation? | 14:13 |
| shaohe_feng | for example, a user want 3 deployables, can he call once allocation? | 14:13 |
| zhipeng | which patch are you talking about ? | 14:13 |
| wangzhh | https://review.openstack.org/#/c/584641/ Maybe this one. | 14:14 |
| shaohe_feng | API part | 14:14 |
| zhipeng | why is it not a good idea ? | 14:14 |
| shaohe_feng | yes. | 14:14 |
| *** shaohe_feng has quit IRC | 14:15 | |
| *** shaohe_feng has joined #openstack-cyborg | 14:15 | |
| shaohe_feng | IMHO, There should better be a explicit API for these two actions | 14:16 |
| shaohe_feng | I also use PATCH for allocation and unallocation for my POC. | 14:16 |
| shaohe_feng | just for I do not touch more cyborg code | 14:16 |
| *** Coco has joined #openstack-cyborg | 14:17 | |
| xinran__ | I think there should be an unified api which does allocation and unallocation | 14:17 |
| zhipeng | xinran__ what do you mean by unified ? | 14:17 |
| xinran__ | Instead of implementing in deployable api | 14:17 |
| shaohe_feng | the PATCH method, it is for resource, not for collections. So it can not support batch allocation | 14:17 |
| Coco | #info Coco | 14:17 |
| Li_Liu | 1 api for both alloc and unalloc? | 14:18 |
| xinran__ | I mean another independent api :) | 14:18 |
| Coco | 2 independent api. | 14:18 |
| xinran__ | #info xinran__ | 14:18 |
| Li_Liu | shaohe_feng, i think as least there is no harm to have the PATCH method, even for long term | 14:18 |
| shaohe_feng | #link https://github.com/shaohef/cyborg/commit/13cb904809376584f3cf78b7d7f120817d83c2ad | 14:19 |
| shaohe_feng | this is a poc about half years ago | 14:19 |
| Coco | patch method can keep, but patch can do many things, not only allocate or unallocate. | 14:20 |
| shaohe_feng | I use it PATCH for unallocation | 14:20 |
| zhipeng | I agree with Li_Liu's assessment, should be good at the moment | 14:20 |
| shaohe_feng | curl -g -i -X PATCH http://localhost:6666/deployables/$UUID -H "Content-Type: application/json" \ | 14:20 |
| shaohe_feng | -H "Accept: application/json" -H "X-Auth-Token: $(openstack token issue -f value -c id)" -d ' | 14:20 |
| shaohe_feng | [ | 14:20 |
| shaohe_feng | { "op": "replace", "path": "/instance_uuid", "value": null } | 14:20 |
| shaohe_feng | ]' | 14:20 |
| shaohe_feng | I agree we do not touch two many codes for cyborg at present. | 14:21 |
| shaohe_feng | tiny change is OK for me as https://review.openstack.org/#/c/584641/ | 14:22 |
| zhipeng | okey then let's wrap up zhenghao and coco's patch, and shaohe_feng could update the cyborgclient | 14:22 |
| zhipeng | I will need to cut the final release for client on 27th | 14:23 |
| wangzhh | So, everyone agree that we should have two another apis for allocate or unallocate? | 14:23 |
| shaohe_feng | but we need dolpher/sunder or Li_Liu comments for it. | 14:23 |
| wangzhh | and... | 14:23 |
| shaohe_feng | we can not get the expect deployables. | 14:23 |
| shaohe_feng | for we need more attributes. | 14:24 |
| wangzhh | shaohe_feng, we can extend parameters if dolpher/sunder or Li_Liu have other comments. | 14:24 |
| shaohe_feng | such as function ID/name and more | 14:24 |
| Li_Liu | shaohe_feng so you want to add more fields in the table? | 14:25 |
| *** shaohe_feng has quit IRC | 14:25 | |
| wangzhh | API is stable. Just extend the filter for querying. | 14:25 |
| wangzhh | Li_Liu, not db. It's for API. | 14:26 |
| *** shaohe_feng has joined #openstack-cyborg | 14:26 | |
| shaohe_feng | For example, I want a crypto FPGA(pre-pre-programmed) | 14:26 |
| Li_Liu | adding fields should not affect api tho | 14:26 |
| shaohe_feng | Yes. so you give the comments ASAP | 14:27 |
| shaohe_feng | need just need experts comments | 14:27 |
| zhipeng | Li_liu plz take a look at https://review.openstack.org/#/c/584641/ | 14:27 |
| zhipeng | and also coco's patch | 14:28 |
| zhipeng | https://review.openstack.org/584296 | 14:28 |
| zhipeng | Li_Liu if you are ok with it plz go head w+1 | 14:28 |
| zhipeng | to land it | 14:28 |
| shaohe_feng | As we have talked, it is easy to improve these patches, as your comments arrives. :) | 14:28 |
| Li_Liu | I was looking as it | 14:29 |
| Li_Liu | will provide comments in a bit | 14:30 |
| shaohe_feng | Thanks. | 14:30 |
| shaohe_feng | For sample scenarios | 14:30 |
| shaohe_feng | There is a QAT and FPGA. | 14:30 |
| shaohe_feng | the user want to cypto function. | 14:31 |
| shaohe_feng | pre-programmed cypto FPGA | 14:32 |
| shaohe_feng | how does he do? | 14:32 |
| shaohe_feng | needs host, devices_type, function_type. | 14:33 |
| shaohe_feng | also the numbers? | 14:33 |
| Li_Liu | one way is to use add_attribute() api in Deployable | 14:33 |
| shaohe_feng | maybe he want to 2 pre-programmed cypto FPGAs | 14:33 |
| shaohe_feng | Li_Liu, I did it as you said. | 14:33 |
| Coco | yes, I think number is necessary. | 14:34 |
| Li_Liu | what kind of numbers? | 14:34 |
| Li_Liu | performance kpi? | 14:34 |
| Li_Liu | like 30 gbps? | 14:34 |
| shaohe_feng | Coco, agree. You can also give the comments on that API patches. | 14:34 |
| Coco | the number of deployables allocated at once. | 14:34 |
| wangzhh | GET will return a list of acc. So we need number in allocate? | 14:35 |
| *** shaohe_feng has quit IRC | 14:35 | |
| Coco | at least, there are some place in the code where we deal with the number requirement of deployables. | 14:35 |
| wangzhh | Batch allocate? | 14:36 |
| Li_Liu | if we have a dedicated allocation api, then the number should be included | 14:36 |
| Li_Liu | I though for now we are just using the deployable PATCH, which is single allocation | 14:36 |
| Coco | OK, than if user ask for 2, we should use the api twice? | 14:37 |
| Coco | then | 14:37 |
| *** shaohe_feng has joined #openstack-cyborg | 14:37 | |
| shaohe_feng | For example, you and I Get 2 accs. | 14:37 |
| Li_Liu | that could a bit tricky | 14:37 |
| shaohe_feng | Then we need allocated them, then risk | 14:38 |
| zhipeng | will user actually needs to simultaneously deploy two kinds of accs ? | 14:39 |
| zhipeng | or more, all at once | 14:39 |
| shaohe_feng | So For my POC. dolpher proposal one API to get and allocated. | 14:39 |
| shaohe_feng | zhipeng, dolper prefer at once. | 14:40 |
| zhipeng | i was thinking about batch actions | 14:40 |
| zhipeng | it makes sense for VMs and containers, since they are mostly homogeneous | 14:40 |
| zhipeng | if fails, rollback is pretty easy | 14:40 |
| Li_Liu | I agree with the multi-alloc use case | 14:41 |
| shaohe_feng | sure. thanks, you got my points. | 14:41 |
| zhipeng | but if we are gonna have batch operation on difference accelerators | 14:41 |
| zhipeng | if they are the same type it will be easy, but for different functionalities, it will be tricky | 14:41 |
| shaohe_feng | It is hard for difference accelerators. | 14:42 |
| shaohe_feng | I have not think a good solutions for it. | 14:42 |
| xinran__ | Cyborg return a list of accelerators and nova will do a for loop to allocate one by one, this is the current solution, but I think we should pass num to cyborg allocate api in the future | 14:42 |
| shaohe_feng | Li_Liu, what's your suggestion on this one? | 14:42 |
| Li_Liu | when calling the dedicated alloc api, just provide the list of acc type you need | 14:42 |
| zhipeng | yes what xinran__ said is okey | 14:42 |
| Li_Liu | for instance, alloc: [aes x 1 + rsa x 2] | 14:43 |
| Li_Liu | that gives you 3 different accs | 14:43 |
| *** shaohe_feng has quit IRC | 14:46 | |
| zhipeng | i think we should follow xinran__'s suggestion | 14:47 |
| zhipeng | let's stuck to the current solution for Rocky | 14:48 |
| zhipeng | and discuss about batch in Denver ptg | 14:48 |
| *** shaohe_feng has joined #openstack-cyborg | 14:48 | |
| Coco | what's the deadline? | 14:48 |
| zhipeng | client is 27th ... | 14:50 |
| Li_Liu | agree, xinran_'s suggestion should solve the problem for us for now | 14:51 |
| Coco | 2 days left? | 14:51 |
| wangzhh | LIke os-acc before. It is urgent.：） | 14:52 |
| zhipeng | yes lol | 14:52 |
| Li_Liu | zhipeng, what else are we trying to squeeze in by 27th? | 14:52 |
| zhipeng | every release is like this | 14:52 |
| zhipeng | just the client lib final cut | 14:52 |
| zhipeng | meaning the basic api will not be changed as well, after that, to make sure the client works | 14:52 |
| Li_Liu | i see | 14:53 |
| zhipeng | shaohe_feng your new patch | 14:53 |
| zhipeng | https://review.openstack.org/#/c/585146/ | 14:53 |
| zhipeng | is about the placement support right ? | 14:53 |
| zhipeng | do we need to remove some old implementation ? | 14:53 |
| zhipeng | I remember Li Liu coded the report functionality before | 14:54 |
| Li_Liu | https://github.com/openstack/cyborg/blob/master/cyborg/services/report.py | 14:54 |
| Li_Liu | I did this part | 14:54 |
| Li_Liu | shaohe_feng, is it sufficient for you? | 14:55 |
| zhipeng | are there any conflict ? | 14:55 |
| xinran__ | client lib depends on cyborg api we don’t have allocation api right now. How we handle that ? | 14:55 |
| zhipeng | I think shaohe added the provider_tree and also make sure the interaction happens on the agent level | 14:55 |
| zhipeng | xinran__ will zhenghao's patch handle that ? | 14:56 |
| *** shaohe_feng has quit IRC | 14:56 | |
| *** shaohe_feng has joined #openstack-cyborg | 14:57 | |
| shaohe_feng | Li_Liu, zhipeng I'm back. | 14:58 |
| shaohe_feng | sorry | 14:58 |
| Li_Liu | I guess shaohe_feng re-implemented my part in his new patch.. | 14:58 |
| shaohe_feng | It support the sub-provider. | 14:58 |
| shaohe_feng | actually, I did not re-implemented it. | 14:58 |
| shaohe_feng | I leverage it from nova | 14:59 |
| Li_Liu | shaohe_feng, I have implemented the SchedulerReportClient in https://github.com/openstack/cyborg/blob/master/cyborg/services/report.py | 14:59 |
| shaohe_feng | Li_Liu, yes, I know your implementations. | 14:59 |
| Li_Liu | so what the difference between your SchedulerReportClient and my SchedulerReportClient? just curious | 14:59 |
| shaohe_feng | no sup-provider. | 14:59 |
| shaohe_feng | it support nest provider. | 15:00 |
| shaohe_feng | I think these code should be in a lib | 15:00 |
| Li_Liu | i see, but should be put them together? | 15:00 |
| shaohe_feng | so nova and cyborg can share. | 15:00 |
| Li_Liu | just use your code | 15:00 |
| shaohe_feng | yes. Maybe it need to remove the old one. | 15:01 |
| Li_Liu | ignore my implementation for now then | 15:01 |
| Li_Liu | ok | 15:01 |
| zhipeng | okey | 15:01 |
| shaohe_feng | And the best solution, move them to a common lib shared by nova and cyborg or other project | 15:01 |
| xinran__ | zhipeng: yeah but we need modify that in the future | 15:01 |
| zhipeng | xinran__ yes for sure | 15:01 |
| shaohe_feng | zhipeng, you can talk about with nova's guy, do they have plan to do it? | 15:02 |
| wangzhh | xinran__， IMHO, we can use PATCH for allocation as my patch in rocky. Or we can design new API interface and parallel development. | 15:02 |
| zhipeng | shaohe_feng I think it is a reasonable request | 15:02 |
| zhipeng | since provider tree has also been implemented for nova-compute | 15:02 |
| *** openstackgerrit has joined #openstack-cyborg | 15:02 | |
| openstackgerrit | Merged openstack/cyborg master: Add "interface_type" field in deployable DB https://review.openstack.org/584296 | 15:02 |
| xinran__ | wangzhh: and deallocate also by patch method ? | 15:02 |
| zhipeng | hey look who's here | 15:02 |
| Li_Liu | a lot of reimplementations cross different project just for this part... | 15:03 |
| shaohe_feng | zhipeng, yes. Need need for us to maintain same code with other project. :) | 15:03 |
| wangzhh | Yes. | 15:03 |
| wangzhh | xinran__ | 15:03 |
| shaohe_feng | Li_Liu, yes. too many. but we should avoid. | 15:03 |
| Li_Liu | agree | 15:03 |
| zhipeng | okey next on drivers | 15:04 |
| shaohe_feng | And that is cyborg should focus on | 15:04 |
| shaohe_feng | that is not | 15:04 |
| shaohe_feng | sorry. | 15:04 |
| zhipeng | we now have gpu and opae based fpga drivers on the fly | 15:04 |
| zhipeng | need brianx__ to start the Xilinx driver ASAP lol | 15:05 |
| xinran__ | Coco: did you modify the driver discover() method to get interface type? | 15:05 |
| zhipeng | let's start with a simple version | 15:05 |
| Coco | I think the yes | 15:05 |
| Coco | I will check again. | 15:06 |
| *** shaohe_feng has quit IRC | 15:06 | |
| Coco | I use the "pci" as the "interface_type" value at this moment, since it's fpga driver. | 15:07 |
| *** shaohe_feng has joined #openstack-cyborg | 15:08 | |
| wangzhh | I think discover should have common data structure. | 15:08 |
| shaohe_feng | I have list cyborg tasks in the etherpad. include this one | 15:08 |
| Coco | I agree with wangzhh | 15:08 |
| shaohe_feng | No one take it at present. | 15:08 |
| Coco | 27th also the deadline? | 15:09 |
| shaohe_feng | Yes. maybe an object | 15:09 |
| shaohe_feng | then it can not need schema verify | 15:09 |
| shaohe_feng | anyway, the goal is unify the discover data | 15:09 |
| Coco | I can take it, but can't make sure it can be done by 27th. | 15:10 |
| zhipeng | does that affect the API behaviour ? | 15:10 |
| Li_Liu | when discover() reports data, it should be in Cyborg understandable format | 15:10 |
| shaohe_feng | Coco, great, thanks. | 15:11 |
| wangzhh | zhipeng, no. Just affect agent. | 15:11 |
| wangzhh | To report data. | 15:11 |
| Li_Liu | no affect on api I don't think | 15:11 |
| zhipeng | okey then there is no hurry | 15:11 |
| shaohe_feng | Coco, have you looked at sundar's VAN? | 15:11 |
| Li_Liu | yup | 15:11 |
| shaohe_feng | Coco, can we leverage it? | 15:11 |
| shaohe_feng | yes, not hurry. | 15:12 |
| Coco | what's the link? | 15:12 |
| shaohe_feng | the spec, let me show you. | 15:12 |
| Coco | ok, thks. | 15:13 |
| shaohe_feng | #link https://review.openstack.org/#/c/577438/ | 15:13 |
| shaohe_feng | it is used for os-acc | 15:13 |
| shaohe_feng | you can have a check, does the drivers can use it? | 15:14 |
| Coco | ok, i will check tomorrow. | 15:16 |
| shaohe_feng | Thanks. | 15:16 |
| zhipeng | Yumeng__ are you still around ? | 15:16 |
| *** shaohe_feng has quit IRC | 15:16 | |
| zhipeng | the doc work should start now | 15:16 |
| Li_Liu | hmm | 15:17 |
| Li_Liu | I will focus on that after warpping up the program api | 15:18 |
| Li_Liu | will as Yumeng and others for help | 15:18 |
| zhipeng | yes will need to work together, to comb through the implementations :) | 15:18 |
| Li_Liu | yup | 15:19 |
| *** shaohe_feng has joined #openstack-cyborg | 15:20 | |
| shaohe_feng | guess she is in sleep. :) | 15:20 |
| Coco | OK, we already had doc wechat group. | 15:20 |
| shaohe_feng | more sleep can keep a girl beauty. :) | 15:21 |
| Coco | .... | 15:22 |
| Coco | I need to go sleep too. | 15:22 |
| zhipeng | okey | 15:22 |
| Li_Liu | have a good sleep guys :) | 15:22 |
