| #openstack-cyborg - 2019-10-17 | |||
| 03:02:14 | chenke | Hi all. | |
| 03:02:26 | Sundar | May be we can wait a couple of minutes for others to join | |
| 03:02:31 | Yumeng | Hi Sundar, hi all | |
| 03:02:35 | s_shogo | Hi all | |
| 03:02:52 | chenke | Ok. | |
| 03:03:12 | Sundar | Today's agenda: https://wiki.openstack.org/wiki/Meetings/CyborgTeamMeeting#Agenda | |
| 03:03:54 | Sundar | PTG etherpad: https://etherpad.openstack.org/p/cyborg-ptg-ussuri | |
| 03:04:51 | Yumeng | emmm... what's the meaning of "Poject updates: Not at Summit, but in etherpad" ? | |
| 03:05:50 | Yumeng | Is it canceled ? | |
| 03:06:56 | openstackgerrit | Xinran WANG proposed openstack/cyborg master: bug fix: ensure resource class instead of getting it. https://review.opendev.org/688231 | |
| 03:07:25 | Sundar | #topic PTG, Summit | |
| 03:07:35 | Sundar | Yumeng: here's the email I got: | |
| 03:07:43 | Sundar | " Due to various constraints, we are unable to record Project Updates this Summit. ... | |
| 03:07:59 | Sundar | We suggest that as an alternative, you record your main updates in an etherpad and use that as a resource to share afterwards. ... | |
| 03:08:09 | xinranwang | Hi, all. Sorry for being late. | |
| 03:08:16 | Sundar | After the event, we’ll send out an email requesting slides and an etherpad link for each project. ... | |
| 03:08:36 | shaohe_feng | hi all | |
| 03:08:39 | shaohe_feng | sorry for late | |
| 03:08:43 | Sundar | Those materials will be placed on the Summit Schedule and we will notify the community once they are live. If you would like to record a version of your presentation and send us a link, we can also add that to the Schedule. " | |
| 03:08:46 | chenke | hi xinran ,shaohe. | |
| 03:08:52 | Sundar | That's the message | |
| 03:09:23 | Yumeng | Alright Thanks! make sense. | |
| 03:09:58 | Sundar | Please add your suggested topics to the PTG etherpad, linked above | |
| 03:10:24 | Sundar | Also, it would be good to have dinner as a team, as we have done before. | |
| 03:10:44 | Sundar | Does Thursday night (Nov 7) work for all of you? | |
| 03:11:46 | chenke | It's ok for me. | |
| 03:11:54 | Yumeng | +1 | |
| 03:11:58 | s_shogo | +1 | |
| 03:12:57 | Sundar | Cool. Let's go with that. If you want to bring anybody else, please go ahead. | |
| 03:13:47 | chenke | Cool. | |
| 03:13:52 | Sundar | I will let you all choose the restaurant! Please make sure it has vegetarian food. :) | |
| 03:15:50 | Sundar | #topic Doc patches | |
| 03:16:16 | Sundar | https://review.opendev.org/#/q/status:open+project:openstack/cyborg+branch:stable/train | |
| 03:16:29 | Sundar | Thanks to Xinran for backporting the doc patches to stable/train | |
| 03:16:50 | Sundar | These were in cyborg master but the release team cut the stable branch after RC1 | |
| 03:17:59 | Sundar | Release team has said we can backport doc patches any time, and they will take effect wothout version number changes | |
| 03:18:03 | Sundar | *without | |
| 03:18:27 | Sundar | So, Yumeng and all, please review it. | |
| 03:18:49 | xinranwang | can we get bug fix patch in now, as the doc patch ;) | |
| 03:19:09 | Yumeng | ok, will do. | |
| 03:19:24 | chenke | Done. | |
| 03:19:48 | Sundar | Nope :( There was lots of resistance to backporting other patches. We can potentially do a point-release early in U if we really want, IMO, all that is beside the point till we get nova integ. | |
| 03:20:18 | Sundar | Once we get nova integ done, we have the option of doing an early point release instead of waiting for April/May | |
| 03:20:52 | Sundar | Basically, non-doc patches require version change. | |
| 03:21:09 | xinranwang | ok, got it. | |
| 03:21:43 | xinranwang | now the doc patch review has high priority. | |
| 03:22:01 | Sundar | Yes. | |
| 03:22:15 | xinranwang | when is the ddl for doc patches? | |
| 03:23:02 | Sundar | No deadline. Train is more or less done. So, we can backport any time | |
| 03:24:36 | Sundar | BTW, Cyborg got some free press in OpenStack press releases: https://www.zdnet.com/article/the-openstack-train-keeps-chugging-on/, https://www.theregister.co.uk/2019/10/15/openstack_train/ | |
| 03:24:44 | Sundar | Kudos to all of you :) | |
| 03:25:30 | Sundar | In other news, Nova-Cyborg interaction spec (https://review.opendev.org/#/c/684151/) got +2 from Nova PTL. Need to follow up more. | |
| 03:26:11 | xinranwang | good news! | |
| 03:26:17 | chenke | Great | |
| 03:26:29 | chenke | will follow up. | |
| 03:27:52 | Sundar | The press articles sound a bit weak because they mentioned only the Nova spec merge. We haven't really claimed that Cyborg supports VM creation etc. in this release. The next release is going to dleiver the goods, and we should be able to make stringer statements. | |
| 03:28:03 | Sundar | *stronger | |
| 03:28:20 | chenke | Ye. | |
| 03:28:44 | Sundar | #topic AoB | |
| 03:28:50 | chenke | Cyborg is a popular project for openstack. | |
| 03:29:00 | Sundar | Yes | |
| 03:29:03 | Sundar | Anything else for today? | |
| 03:29:25 | chenke | I want to confirm that the version has been sent out. Does it make sense to change the documentation? | |
| 03:30:02 | Sundar | Are you asking if it is ok to change the docs after Train has shipped? | |
| 03:30:04 | chenke | If users take the version, they won't get the latest documents | |
| 03:30:33 | Sundar | Hmm, if they clone stable/train in the future, after we merge the doc patches, they will get them all. | |
| 03:30:33 | chenke | Has the train been sent out? | |
| 03:31:09 | chenke | Yes. If they clone the stable/train , they will get them. | |
| 03:31:15 | Sundar | More or less: https://review.opendev.org/#/c/687991/ has bene merged | |
| 03:31:53 | Sundar | I think they have some backend work. It should be done by this week, I think | |
| 03:32:31 | shaohe_feng | Will this release add more ACC support? | |
| 03:32:49 | Sundar | Do you mean if we get more drivers in U? | |
| 03:32:49 | shaohe_feng | another questions. | |
| 03:32:54 | shaohe_feng | yes. | |
| 03:33:02 | shaohe_feng | more drivers? | |
| 03:33:10 | shaohe_feng | any plane for it? | |
| 03:34:16 | shaohe_feng | Do we support apply FPGA pf to a VM? | |
| 03:34:36 | Sundar | We could. We need to talk about it. Right now, we got some drivers for GPU and Ascend. However, the maintainers are not regularly participating in Cyborg activities. That makes me concerned about maintenance. Also, we don;t have 3rd party CI for any driver yet. We are planning that for FPGAs, but what about other drivers? | |
| 03:35:01 | Sundar | I was replying about drivers, not PF | |
| 03:35:27 | shaohe_feng | so the questions is that. | |
| 03:35:43 | shaohe_feng | If a end user apply a FPGA | |
| 03:35:43 | Sundar | As a team, we may have to decide on a higher bar for drivers. That is something we can discuss here on at the PTG. | |
| 03:35:45 | Sundar | *or | |
| 03:35:56 | shaohe_feng | I will not attend PTG. | |
| 03:36:29 | Sundar | Ah yes, too bad. You can give your ideas here or in the PTG etherpad. | |
| 03:36:30 | shaohe_feng | if he found there's bug on his bitstream? | |
| 03:36:50 | shaohe_feng | what should he do? | |
| 03:37:06 | shaohe_feng | delete the VM, rebuild a new VM with a FPGA? | |
| 03:37:14 | Sundar | Passing a FPGA PF to a VM is potential security hole, because we don;t know what bitstreams get programmed | |
| 03:37:14 | s_shogo | Wow, it's so good > CI for FPGA driver's. | |
| 03:37:22 | shaohe_feng | or just re-program it? | |
| 03:38:21 | Sundar | We have a usage model called Runtime Programming, which we don't support today. It involves VM issuing requests for new bitstreams, Cyborg or something receives that request and does the reprogramming. We don;t see many customers asking for that | |
| 03:38:42 | shaohe_feng | maybe, the end user after doing his AI, then he want to change the AI model, which means he maybe need a new bitstream for his AI net model. | |
| 03:38:48 | shaohe_feng | what should he do? | |
| 03:39:16 | xinranwang | I think we can provider a program interface for this kind of users. | |
| 03:39:25 | xinranwang | in vf use case. | |
| 03:39:44 | Sundar | He could get the VM to issue a request somehow to underlying infra. That is not there today. Today, he only needs to stop that VM and start a new one | |
| 03:40:13 | Sundar | xinranwang: User cannot reprogram a FPGA via VF. | |
| 03:40:59 | shaohe_feng | yes, but he take a great effort to setup his AI env, such as install the openvino and the dependency, set connection with the camera maybe. | |
| 03:41:07 | xinranwang | if boot with bit-stream failed, vm should become failed. if user boot a vm successfully, and want reprogram the FPGA, what will we do. | |
