| 14:06:21 | zhipeng | shaohe_feng will sundar attend ? | |
| 14:06:50 | shaohe_feng | zhipeng, I do not think so | |
| 14:07:00 | zhipeng | on vacation ? | |
| 14:07:00 | shaohe_feng | he is on vocation. | |
| 14:07:02 | shaohe_feng | yes | |
| 14:07:12 | zhipeng | until when ? | |
| 14:07:25 | shaohe_feng | seems \7/25 | |
| 14:08:11 | shaohe_feng | from July 10 night through July 25, coming back on 26th. | |
| 14:08:22 | zhipeng | lol | |
| 14:08:40 | Coco_Gao | long vacation. | |
| 14:08:48 | zhipeng | okey let's get into business | |
| 14:09:00 | zhipeng | #topic Rocky Development Update | |
| 14:09:05 | zhipeng | #link https://review.openstack.org/#/q/status:open+project:openstack/cyborg | |
| 14:09:12 | zhipeng | #topic os-acc design | |
| 14:09:33 | zhipeng | https://review.openstack.org/577438 | |
| 14:09:56 | zhipeng | Li_Liu shaohe_feng is there any consensus converging on the current proposal ? | |
| 14:11:26 | Li_Liu | I don't have any further comments on that one | |
| 14:11:38 | zhipeng | meaning satisfied ? | |
| 14:11:45 | zhipeng | or still waiting for answers | |
| 14:11:47 | shaohe_feng | I really want to know the scope of the os-acc. | |
| 14:12:34 | shaohe_feng | will it cover the program and instance binding? | |
| 14:14:20 | shaohe_feng | we have not define the binding interface. The binding should pass hostname and instance uuid and request spec. | |
| 14:14:32 | zhipeng | Li_Liu wangzhh Coco-Gao what's your opinion | |
| 14:14:55 | wangzhh | I think so. os-acc call cyborg to program and bind. | |
| 14:15:36 | Li_Liu | it should be able to call the program API | |
| 14:16:04 | shaohe_feng | rest full API | |
| 14:16:15 | shaohe_feng | ? | |
| 14:16:22 | Li_Liu | but how it calls it is the problem here | |
| 14:16:23 | wangzhh | Not just restful api. | |
| 14:16:32 | Li_Liu | exactly | |
| 14:16:43 | Li_Liu | rest/rpc/something else? | |
| 14:17:14 | Li_Liu | for the moment, the most intuitive way is calling the REST API I am currently writing | |
| 14:17:35 | shaohe_feng | can program also call RPC? | |
| 14:17:46 | zhipeng | wangzhh how's the os-brick handling the attach ? | |
| 14:17:58 | Coco_Gao | wangzhh sundar suggest to use rpc call? | |
| 14:18:14 | wangzhh | I've talked to Sundar about it. We agreed that os-acc should call not just api. | |
| 14:19:06 | wangzhh | In fact, call api only is another option. | |
| 14:19:38 | zhipeng | besides api what could it call ? | |
| 14:20:29 | Li_Liu | Maybe allowing os-acc directly call the vendor driver api is another option | |
| 14:20:53 | zhipeng | that would be the original design right ? | |
| 14:21:02 | zhipeng | contain it on the compute node level | |
| 14:21:08 | zhipeng | without any api interactions | |
| 14:21:19 | wangzhh | In some cases, we must call api. But sometimes, rpc call is a good code path, too. | |
| 14:21:33 | Coco_Gao | os-acc call cyborg-agent using rpc? | |
| 14:21:56 | wangzhh | CoCo: Yes | |
| 14:22:17 | wangzhh | The original design right. | |
| 14:23:01 | Coco_Gao | ok, when should we use rpc and when should we use api? | |
| 14:23:27 | wangzhh | Sorry, lost an "is". | |
| 14:24:41 | wangzhh | Attach, deatch use rpc. | |
| 14:26:44 | Li_Liu | zhipeng: "contain it on the compute node level". that should be the easiest way for now | |
| 14:27:00 | zhipeng | will attach/detach involving binding shaohe_feng mentioned ? | |
| 14:29:38 | xinran__ | Binding is before attach I think？ | |
| 14:30:08 | zhipeng | bind the vm instance with the acc instance ? | |
| 14:30:18 | zhipeng | do we have similar process in other module ? | |
| 14:31:09 | Li_Liu | the binding should be taken care of before the process get to the vendor driver | |
| 14:31:13 | wangzhh | Neutron | |
| 14:31:40 | zhipeng | i think there was a comment from Sundar states that it is kinda different for neutron | |
| 14:31:46 | zhipeng | the port binding | |
| 14:31:48 | wangzhh | Nova call neutron-agent directly to allocate port. | |
| 14:31:50 | zhipeng | and the acc binding | |
| 14:33:15 | zhipeng | okey let's arrange another ZOOM call for specificities | |
| 14:33:28 | zhipeng | the big problem here is about the os-acc scope, like shaohe said | |
| 14:33:37 | zhipeng | what we want it to be for Rocky release | |
| 14:33:46 | wangzhh | In my opinion, we can imply it as the design now. For the api and os-acc are stable. We can refactor it if needed. | |
| 14:33:57 | zhipeng | bare minimum , or we want binding, programming in it as well | |
| 14:34:36 | zhipeng | we need to start implementation as soon as possible for sure | |
| 14:34:50 | Li_Liu | I agree with wangzhh, we should get the thing working first | |
| 14:35:03 | Li_Liu | ZOOM call would be great | |
| 14:35:24 | zhipeng | Li_Liu will it block FPGA programing if os-acc does not include program support ? | |
| 14:36:07 | Li_Liu | no it should not as my programming support is a stand alone feature | |
| 14:36:15 | Li_Liu | it does not depends on others | |
| 14:36:57 | zhipeng | okey then let's shoot for the minimum feature goal | |
| 14:37:26 | zhipeng | shall we have a ZOOM meeting say 10:00 am tmr ? | |
| 14:37:35 | zhipeng | discuss os-acc in detail ? | |
| 14:37:53 | Li_Liu | you mean china time? | |
| 14:38:07 | zhipeng | yes, 10:00pm for Toronto | |
| 14:38:14 | Li_Liu | should be fine | |
| 14:38:17 | zhipeng | about less than 12 hours later | |
| 14:38:22 | Li_Liu | up to you guys | |
| 14:38:33 | zhipeng | wangzhh shaohe_feng Coco-Gao okey ? | |
| 14:38:53 | wangzhh | I'm OK. | |
| 14:39:03 | Coco_Gao | ok | |
| 14:39:34 | zhipeng | ok then I assume shaohe is ok as well :) | |
| 14:39:37 | zhipeng | moving on | |
| 14:39:43 | zhipeng | #topic GPU driver | |
| 14:39:44 | sum12 | could you guys post some notes about your discussion ? | |
| 14:39:53 | zhipeng | sum12 definitely | |
| 14:40:20 | zhipeng | wangzhh any timeline for the GPU driver ? | |
| 14:40:36 | zhipeng | #link https://review.openstack.org/574075 | |
| 14:41:04 | wangzhh | I'll update the commit tmr. | |
| 14:41:23 | zhipeng | can you also reply to the NVIDIA guy ? | |
| 14:41:36 | zhipeng | i remember he asked about an introduction about the driver code | |
| 14:41:40 | zhipeng | in the email thread | |
| 14:41:44 | wangzhh | Of course. I have promised Mike. | |
| 14:42:13 | zhipeng | gr8t :) | |
| 14:42:16 | zhipeng | moving on | |
