| zhipeng_ | hey | 15:03 |
| zhipeng_ | let's go | 15:03 |
| zhipeng_ | #startmeeting openstack-cyborg | 15:03 |
| openstack | Meeting started Wed Apr 5 15:03:38 2017 UTC and is due to finish in 60 minutes. The chair is zhipeng_. Information about MeetBot at http://wiki.debian.org/MeetBot. | 15:03 |

| openstack | The meeting name has been set to 'openstack_cyborg' | 15:03 |
| zhipeng_ | #info zhipeng crushil | 15:03 |
| zhipeng_ | who else do we have at the meeting ? | 15:04 |
| jkilpatr | o/ | 15:10 |
| jkilpatr | sorry I'm late | 15:10 |
| zhipeng_ | no problem,just saw your patch | 15:12 |
| zhipeng_ | #topic BP discussion | 15:12 |
| zhipeng_ | I must apologize that due to the cloudnativecon week, I have not been attentive to the api BP | 15:12 |
| zhipeng_ | will get to it starting tmr I hope | 15:13 |
| zhipeng_ | crushil jkilpatr could you guys walk through the updates ? | 15:13 |
| crushil | Sure | 15:13 |
| jkilpatr | crushil, you first? | 15:14 |
| crushil | yup | 15:14 |
| crushil | Updated the bp for the generic driver implementation and trying to incorporate all the changes that were requested | 15:14 |
| crushil | Did some reviews on other BPs as well and waiting for the BP owners to come back with a response | 15:15 |
| zhipeng_ | crushil cool man, any outstanding issues at the moment ? | 15:15 |
| crushil | The generic driver implementation bp is at https://review.openstack.org/#/c/447257/ | 15:15 |
| crushil | zhipeng_, Nope, just need more review comments atm | 15:16 |
| zhipeng_ | great :) | 15:16 |
| zhipeng_ | jkilpatr how about your updates ? | 15:18 |
| jkilpatr | So I still need to address a review from a Friday. It's not going to be the conductor's responsibility to attach accelerators, so I need to remove it from that part of the loop | 15:18 |
| jkilpatr | then I think I'll be taking the suggestion to move setup responsiblities out of the conductor. | 15:18 |
| jkilpatr | for the time being I guess we can maintain a directory of setup playbooks and document how to use them. | 15:19 |
| jkilpatr | I also need to actually write the caching stuff we talked about in the last meeting. Might try and get through that today | 15:19 |
| jkilpatr | that's all. | 15:19 |
| zhipeng_ | i don't remember we had discussion on moving out setup functionalities | 15:20 |
| zhipeng_ | is it from the review ? | 15:20 |
| jkilpatr | zhipeng_, it's in the review comments. | 15:20 |
| zhipeng_ | my network is dreadfully slow now ... so comments from _gryf ? | 15:21 |
| jkilpatr | Roman doesn't like the idea of having a program run off and install it's own dependencies. Which I can understand. | 15:21 |
| zhipeng_ | i thought we had a understanding that agent could do the ansible stuff | 15:21 |
| zhipeng_ | okey i will dig into Roman's comment later | 15:23 |
| jkilpatr | There are arguments from both sides, on one hand ease of setup, on the other the potential conseqences of cyborg running wild with root. | 15:24 |
| jkilpatr | in the end we're planning on making the same playbooks and just having a human press the button instead of the agent. | 15:24 |
| zhipeng_ | so if we do the setup as a out-of-band operation | 15:24 |
| zhipeng_ | okey | 15:25 |
| zhipeng_ | but I do have some scenarios that maybe still the agent should do the setup, despite of the security concerns | 15:26 |
| zhipeng_ | for example for some dataplane virtualization techniques, you could compose a set up virtual functions into one bigger function | 15:27 |
| zhipeng_ | a case wouldbe to compose a virtual FW on a intelligent NIC card | 15:27 |
| zhipeng_ | using different dedicated small virtual networking functions which will do q-in-q, switching respectively | 15:28 |
| zhipeng_ | jkilpatrt I think the overall question is that , could we have a compromise between the two sides ? | 15:29 |
| jkilpatr | zhipeng_, I think we could find some sort of compromise I'm just not sure where to draw the line | 15:31 |
| zhipeng_ | I was thinking the line could be where the root privilege is required | 15:32 |
| zhipeng_ | if the root is required on the host side, then maybe it is good, as Roman suggested, to leave to the humans | 15:32 |
| jkilpatr | that sounds reasonable enough. | 15:32 |
| zhipeng_ | but if it is root privilege on the smart device | 15:32 |
| zhipeng_ | then we could, at the moment, assume that the conductor could perform the setup with root privilege | 15:33 |
| zhipeng_ | it has security concerns as well, no doubt, but i think we could deal with it later on | 15:33 |
| jkilpatr | you're talking about permissions levels on the accelerator itself? What is the "smart device" ? | 15:34 |
| zhipeng_ | yes i was. smart device like intelligent NICs I referred to | 15:35 |
| zhipeng_ | there are FPGA enabled devices that you could program the "micro" virtual functions | 15:36 |
| zhipeng_ | deploy them in different ways to compose different functionalities | 15:36 |
| zhipeng_ | it is not widely used yet, but I think it would be a major use case later on | 15:36 |
| jkilpatr | I know FPGA's can be deployed like that but I never thought about user levels on them. | 15:37 |
| zhipeng_ | for example in edge computing, where you could dynamically compose your network dataplane | 15:37 |
| zhipeng_ | that was just my thinking | 15:37 |
| jkilpatr | it makes sense, just never considered it that way. | 15:38 |
| zhipeng_ | if we could have cyoborg agent setup an ansible playbook on a rasberry pie | 15:38 |
| zhipeng_ | that would be supper awesome :P | 15:39 |
| jkilpatr | but why? | 15:39 |
| zhipeng_ | (just thinking out loud) | 15:39 |
| zhipeng_ | never mind the pie example | 15:40 |
| zhipeng_ | so I think I will also comment on the patch, to see what's _gryf's take on this | 15:40 |
| zhipeng_ | if in the end , the dynamic composition FPGA use case is still too far fetch, then we could just have the regular playbook procedure | 15:41 |
| jkilpatr | I think that's fine for now. Maybe add some notifications to the operator that things need to be setup. | 15:43 |
| jkilpatr | I think we could detect new accelerators without root | 15:43 |
| zhipeng_ | yes that is ture | 15:43 |
| zhipeng_ | true ... | 15:43 |
| zhipeng_ | fat fingers | 15:43 |
| zhipeng_ | #topic AoB | 15:44 |
| zhipeng_ | okey any other buisness or topics | 15:44 |
| crushil | Not from me | 15:46 |
| jkilpatr | not from me either | 15:48 |
| zhipeng_ | okey thank you guys for the great work on the bp patches, let's conclude the meeting earlier today :) | 15:48 |
| zhipeng_ | see you guys on gerrit :P | 15:48 |
