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 15:18:51 <jkilpatr> then I think I'll be taking the suggestion to move setup responsiblities out of the conductor. 15:19:15 <jkilpatr> for the time being I guess we can maintain a directory of setup playbooks and document how to use them. 15:19:50 <jkilpatr> I also need to actually write the caching stuff we talked about in the last meeting. Might try and get through that today 15:19:52 <jkilpatr> that's all. 15:20:19 <zhipeng_> i don't remember we had discussion on moving out setup functionalities 15:20:34 <zhipeng_> is it from the review ? 15:20:48 <jkilpatr> zhipeng_, it's in the review comments. 15:21:15 <zhipeng_> my network is dreadfully slow now ... so comments from _gryf ? 15:21:33 <jkilpatr> Roman doesn't like the idea of having a program run off and install it's own dependencies. Which I can understand. 15:21:42 <zhipeng_> i thought we had a understanding that agent could do the ansible stuff 15:23:17 <zhipeng_> okey i will dig into Roman's comment later 15:24:17 <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. 15:24:48 <jkilpatr> in the end we're planning on making the same playbooks and just having a human press the button instead of the agent. 15:24:52 <zhipeng_> so if we do the setup as a out-of-band operation 15:25:07 <zhipeng_> okey 15:26:29 <zhipeng_> but I do have some scenarios that maybe still the agent should do the setup, despite of the security concerns 15:27:24 <zhipeng_> for example for some dataplane virtualization techniques, you could compose a set up virtual functions into one bigger function 15:27:47 <zhipeng_> a case wouldbe to compose a virtual FW on a intelligent NIC card 15:28:25 <zhipeng_> using different dedicated small virtual networking functions which will do q-in-q, switching respectively 15:29:02 <zhipeng_> jkilpatrt I think the overall question is that , could we have a compromise between the two sides ? 15:31:01 <jkilpatr> zhipeng_, I think we could find some sort of compromise I'm just not sure where to draw the line 15:32:00 <zhipeng_> I was thinking the line could be where the root privilege is required 15:32:24 <zhipeng_> if the root is required on the host side, then maybe it is good, as Roman suggested, to leave to the humans 15:32:39 <jkilpatr> that sounds reasonable enough. 15:32:40 <zhipeng_> but if it is root privilege on the smart device 15:33:06 <zhipeng_> then we could, at the moment, assume that the conductor could perform the setup with root privilege 15:33:31 <zhipeng_> it has security concerns as well, no doubt, but i think we could deal with it later on 15:34:30 <jkilpatr> you're talking about permissions levels on the accelerator itself? What is the "smart device" ? 15:35:51 <zhipeng_> yes i was. smart device like intelligent NICs I referred to 15:36:13 <zhipeng_> there are FPGA enabled devices that you could program the "micro" virtual functions 15:36:27 <zhipeng_> deploy them in different ways to compose different functionalities 15:36:49 <zhipeng_> it is not widely used yet, but I think it would be a major use case later on 15:37:08 <jkilpatr> I know FPGA's can be deployed like that but I never thought about user levels on them. 15:37:08 <zhipeng_> for example in edge computing, where you could dynamically compose your network dataplane 15:37:46 <zhipeng_> that was just my thinking 15:38:09 <jkilpatr> it makes sense, just never considered it that way. 15:38:56 <zhipeng_> if we could have cyoborg agent setup an ansible playbook on a rasberry pie 15:39:03 <zhipeng_> that would be supper awesome :P 15:39:22 <jkilpatr> but why? 15:39:49 <zhipeng_> (just thinking out loud) 15:40:12 <zhipeng_> never mind the pie example 15:40:34 <zhipeng_> so I think I will also comment on the patch, to see what's _gryf's take on this 15:41:17 <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 15:43:04 <jkilpatr> I think that's fine for now. Maybe add some notifications to the operator that things need to be setup. 15:43:14 <jkilpatr> I think we could detect new accelerators without root 15:43:39 <zhipeng_> yes that is ture 15:43:43 <zhipeng_> true ... 15:43:49 <zhipeng_> fat fingers 15:44:00 <zhipeng_> #topic AoB 15:44:09 <zhipeng_> okey any other buisness or topics 15:46:13 <crushil> Not from me 15:48:40 <jkilpatr> not from me either 15:48:45 <zhipeng_> okey thank you guys for the great work on the bp patches, let's conclude the meeting earlier today :) 15:48:53 <zhipeng_> see you guys on gerrit :P 15:48:58 <zhipeng_> #endmeeting
