| 14:06:38 | Li_Liu | Welcome Melissa! | |
| 14:06:50 | Melissa_S | Likewise :) | |
| 14:07:33 | Sundar | Hi Melissa, welcome! Good to have you here. | |
| 14:07:58 | Melissa_S | Thanks Sundar :) | |

| 14:08:58 | kosamara | hi! | |
| 14:09:04 | zhipeng | Hey ! | |
| 14:09:11 | Yumeng__ | #info Yumeng__ | |
| 14:09:14 | Yumeng__ | Hi | |
| 14:09:23 | zhipeng | Hi Yumeng :) | |
| 14:09:42 | Yumeng__ | Hi zhipeng | |
| 14:10:16 | chucksong | Hi everyone! | |
| 14:10:37 | zhipeng | Hi chucksong | |
| 14:10:44 | zhipeng | don't believe we met before | |
| 14:10:52 | zhipeng | can you introduce yourself a little bit ? | |
| 14:11:12 | chucksong | yes, I am Chuck Song of Xilinx | |
| 14:11:27 | chucksong | Currently taking charge of the FaaS team | |
| 14:11:41 | chucksong | I suppose we are going to talk about the Cyborg project. | |
| 14:11:45 | zhipeng | FPGA as a service ? | |
| 14:11:48 | chucksong | yes | |
| 14:11:50 | Sundar | Hi Chuck, welcome! | |
| 14:11:56 | Li_Liu | Hi Chuck | |
| 14:12:12 | Li_Liu | We have a lot people joining :) | |
| 14:12:15 | chucksong | hi Sundar and LiLiu | |
| 14:12:41 | zhipeng | let's get into business :) | |
| 14:12:50 | zhipeng | #topic sub-team report | |
| 14:13:22 | zhipeng | I think we could start with release subteam | |
| 14:13:49 | zhipeng | #link https://review.openstack.org/558223 | |
| 14:14:16 | zhipeng | #info cyborg has been added for milestone based release | |
| 14:14:44 | zhipeng | that was part of Rocky goal | |
| 14:15:05 | Sundar | Is Apr 19 the spec freeze day for Cyborg too? | |
| 14:16:08 | zhipeng | yes Sudnar the week of Apr 16 to Apr 20 | |
| 14:16:23 | zhipeng | will be our very first deadline for spec freeze :) | |
| 14:16:44 | Melissa_S | what do you need delivered on the Xilinx side before freeze? | |
| 14:17:45 | Melissa_S | Pardon me - I am new to the project :) | |
| 14:18:00 | zhipeng | Melissa_S altho currently all the drivers are in-tree which means Xilinx driver also needs a spec | |
| 14:18:00 | Li_Liu | I think the major thing we need is Xilinx Device driver. But that doesn't have to be before spec freeze I think | |
| 14:18:17 | zhipeng | but driver spec freeze should be expected for Rocky MS-2 | |
| 14:18:28 | zhipeng | which will be week of Jun 04-Jun08 | |
| 14:18:30 | Li_Liu | Does the vendor specific driver need a spec Howord? | |
| 14:18:44 | zhipeng | Li_Liu at the moment yes | |
| 14:18:47 | Li_Liu | ok | |
| 14:19:10 | zhipeng | but yes as Li_Liu said, plz don't wait for the deadline :) | |
| 14:19:12 | Sundar | Not to jump the gun :) but could I ask folks to review https://etherpad.openstack.org/p/Cyborg-Nova-Multifunction so that I can update https://review.openstack.org/#/c/554717/ ? | |
| 14:19:38 | Sundar | This is based on the latest proposal from Nova community | |
| 14:19:51 | zhipeng | Sundar will go into that very soon :) | |
| 14:19:56 | Li_Liu | sure, I will take a look | |
| 14:20:03 | zhipeng | Let's finish the subteam report first | |
| 14:20:32 | zhipeng | Melissa_S chucksong plz refer to https://releases.openstack.org/rocky/schedule.html#r-release | |
| 14:20:41 | zhipeng | for the general milestone sched | |
| 14:21:10 | Sundar | Thanks, Li_Liu and Howard | |
| 14:21:45 | Melissa_S | Yes - thank you. | |
| 14:22:09 | zhipeng | Cyborg's specific sched could be found http://eavesdrop.openstack.org/meetings/openstack_cyborg/2018/openstack_cyborg.2018-03-14-14.07.html | |
| 14:22:28 | zhipeng | okey moving on | |
| 14:22:50 | zhipeng | Yumeng__ could you update the progress on your side ? | |
| 14:23:54 | Yumeng__ | I sent out a update about the high time synchronisation card on the mail list | |
| 14:24:05 | Yumeng__ | Pls check | |
| 14:24:29 | Yumeng__ | And launchpad migration to storyboard will be done soon. | |
| 14:25:00 | zhipeng | did you just send the clock driver proposal ? | |
| 14:25:05 | zhipeng | or maybe I missed it ? | |
| 14:25:50 | Yumeng__ | 1 second | |
| 14:26:36 | zhipeng | BTW in case everyone not follow the storyboard migration, plz refer to | |
| 14:26:39 | zhipeng | #link https://review.openstack.org/#/c/558327/ | |
| 14:26:52 | Yumeng__ | https://docs.openstack.org/infra/manual/zuulv3.html | |
| 14:27:14 | Yumeng__ | Pls go ahead, I will send out the right link | |
| 14:27:28 | zhipeng | #link https://review.openstack.org/558821 | |
| 14:28:02 | zhipeng | #info storyboard migration for cyborg | |
| 14:28:47 | zhipeng | thx Yumeng__ :) doc subteam has been very responsive and active | |
| 14:29:17 | zhipeng | Melissa_S chucksong Dutch signed on as co-lead for the driver sub-team | |
| 14:29:35 | zhipeng | does one of you guys maybe interested in take the role ? | |
| 14:29:52 | zhipeng | help update and coordinate the driver development for Rocky ? | |
| 14:30:31 | Melissa_S | Chuck and I can work on this | |
| 14:30:57 | zhipeng | great :) | |
| 14:31:11 | Melissa_S | I think you could put Chuck's name down - he is on the apps side | |
| 14:31:24 | zhipeng | duly noted :) | |
| 14:31:30 | Melissa_S | we will find the correct internal team for this project | |
| 14:31:35 | zhipeng | #topic critical rocky spec review | |
| 14:32:02 | zhipeng | first up, Sundar's Nova-Cyborg interaction spec | |
| 14:32:22 | chucksong | zhipeng, yes I will take the role | |
| 14:32:25 | zhipeng | Sundar could you help get everyone up to speed ? | |
| 14:33:26 | Sundar | Sure, Howard | |
| 14:33:27 | zhipeng | #info Sundar cyborg-nova spec discussion | |
| 14:33:30 | zhipeng | #link https://etherpad.openstack.org/p/Cyborg-Nova-Multifunction | |
| 14:33:46 | zhipeng | #link https://review.openstack.org/#/c/554717/ | |
| 14:34:01 | Sundar | We had arrived at a way of representing FPGA components in Nova, and worklfows for all use cases based on hat representation, back in the PTG | |
| 14:34:26 | Sundar | The spec that Howard provided above codifies that | |
| 14:35:01 | Sundar | However, there was a race condition for one use case, which has been debated in the community. An analogy was found with a vGPU issue, and a joint solution was proposed | |
| 14:35:27 | Sundar | http://lists.openstack.org/pipermail/openstack-dev/2018-March/128888.html | |
| 14:35:41 | zhipeng | #link http://lists.openstack.org/pipermail/openstack-dev/2018-March/128888.html | |
| 14:36:03 | Sundar | Based on that, I worked out the details, in a way that should cover GPUs etc. but probably focuses more on FPGAs. | |
| 14:36:16 | Sundar | #link https://etherpad.openstack.org/p/Cyborg-Nova-Multifunction | |
| 14:36:38 | Sundar | I think this is a better solution than the PTG flow :) both for Nova and Cyborg | |
| 14:37:34 | Sundar | For Cyborg, this means that we don't need to keep accelerator usage details in Cyborg DB -- just use placement info :) | |
| 14:38:16 | Sundar | Eventually, if/when Nova supports preferred traits, maybe we don't need the weigher -- but we can evaluat that when it becomes real | |
| 14:38:54 | Sundar | For the new folks in Cyborg, this may sound cryptic :) I am open to walking folks through the proposal in a call if needed | |
| 14:39:27 | Sundar | Howard, do you want me to explain the crux of the proposal here? | |
| 14:39:28 | Li_Liu | Sundar, regardless, we still need to track individual assignment for each device in Cyborg, right? | |
| 14:40:04 | zhipeng | Sundar it would be great to have a brief walk through and the central take aways :) | |
| 14:40:07 | Sundar | Li_Liu: Yes, we will be handling acceleratr -PF/VF matching | |
| 14:40:46 | Sundar | That is not involve din the scheduling, because Placement counts accelerator resources | |
