| #openstack-cyborg - 2018-05-28 | |||
| 14:33:57 | shaohe_feng | I remeber nova update the placement in n-cpu (same with cyborg agent) | |
| 14:34:01 | Li_Liu | I think agent for sure needs to update placement | |
| 14:34:19 | shaohe_feng | I think so. | |
| 14:35:21 | shaohe_feng | This is NOVA BP for nest provider | |
| 14:35:22 | shaohe_feng | #link https://blueprints.launchpad.net/nova/+spec/nested-resource-providers | |
| 14:35:30 | Li_Liu | in terms of conductor, I am not sure, but I think Cyborg controller needs to update placement | |
| 14:37:45 | shaohe_feng | Li_Liu, I found you have add placement client in Cyborg | |
| 14:38:16 | Li_Liu | yes | |
| 14:38:16 | shaohe_feng | Guess it does not support nest provider, right? | |
| 14:38:35 | Li_Liu | at that time, prob not | |
| 14:38:40 | shaohe_feng | Nova's nest provider patch has been merged. | |
| 14:39:01 | Li_Liu | sure, I will see what I can do about it | |
| 14:39:29 | shaohe_feng | So in cyborg, we can support nest provider. | |
| 14:39:45 | Li_Liu | yup, we should | |
| 14:40:13 | shaohe_feng | and last IRC meeting, we have agreement to support multi-resource classes. | |
| 14:40:30 | shaohe_feng | nest provider + multi-resource classes | |
| 14:40:43 | Li_Liu | ok | |
| 14:41:31 | shaohe_feng | Ok, I think that's all from me. | |
| 14:42:06 | shaohe_feng | Li_Liu, anything more need to discuss or update? | |
| 14:42:16 | Li_Liu | a lot things need to work on | |
| 14:42:22 | shaohe_feng | yes. | |
| 14:42:41 | shaohe_feng | What's else can I help, let me know. | |
| 14:42:58 | Li_Liu | sure, will let you know in case I need help | |
| 14:44:01 | shaohe_feng | OK, let's work together to push cybork keep going | |
| 14:44:51 | Li_Liu | I will try to give a summary on the summit during the project general irc this week | |
| 14:45:22 | shaohe_feng | good, expect it. Thanks. | |
| 14:46:05 | shaohe_feng | If no more, we can end the meeting. | |

| 14:09:30 | sum12 | no meeting today ? | |
| 14:10:10 | Li_Liu | still waiting for Howard | |
| 14:10:44 | Li_Liu | shaohe_feng can you start the meeting for us? | |
| 14:10:56 | Li_Liu | in case Howard is in middle of something\ | |
| 14:11:28 | Sundar | The meeting topic is set to 'spec review day'. Was that announced earlier? | |
| 14:12:19 | Li_Liu | I think that is for a few week earlier | |
| 14:14:19 | shaohe_feng | Li_Liu, hello | |

| 14:17:39 | Li_Liu | am I doing it right? | |
| 14:17:55 | Li_Liu | changing the topic | |
| 14:18:02 | shaohe_feng | yes. | |
| 14:18:33 | shaohe_feng | welcome Li_Liu introduce his experience during summit. | |
| 14:18:58 | Li_Liu | ok, a few of us went to the summit last week. Welcome to Canada for those of you who came | |
| 14:19:30 | Li_Liu | We had a few talks given regarding to Cyborg | |
| 14:20:22 | Li_Liu | I gave a Cyborg project update. Friends from Lenovo gave a demo using Cyborg to manage GPUs in their ThinkCloud product | |
| 14:20:56 | Li_Liu | JF. Ding also gave a talk with 99 cloud folks, which involves cyborg a lot | |
| 14:21:29 | Li_Liu | the general feedback is great. A lot of attentions are coming the way to Cyborg | |
| 14:21:40 | shaohe_feng | good. | |
| 14:22:06 | Li_Liu | couple quick comments from the audiences | |
| 14:22:40 | sum12 | any recurring comments ? | |
| 14:23:23 | Li_Liu | 1. Managing GPUs is still not a killer app for Cyborg. Prob showing other capabilities on top of this might draw more attentions | |
| 14:25:12 | Li_Liu | 2. In order to become a strong piece of OpenStack or even addition to k8s in the future, we need to push the development further and faster | |
| 14:25:36 | Li_Liu | as we are actually facing competitions from the Nova vGPU management. | |
| 14:26:09 | Li_Liu | currently we are at pretty much the same stage as them. | |
| 14:27:28 | Li_Liu | some people are looking at us since they think currently vGPU management in Nova should just be temperate. | |
| 14:28:14 | Li_Liu | They believe once Cyborg becomes more mature, it should be the one actually solve the general problem | |
| 14:28:32 | Li_Liu | This is from me. | |
| 14:28:41 | Li_Liu | anyone else has anything to share? | |
| 14:29:24 | Sundar | I moderated a session on Cyborg/FPGA in Cloud/NFV. | |
| 14:29:56 | shaohe_feng | Sundar, can you give a summary about it? | |
| 14:30:04 | Sundar | It was meant for discussion with operators and end users. We had Verizon, SKA and CERN there, apart from many developers, incl. Nova developers | |
| 14:30:35 | Sundar | The discusison is here: #link https://etherpad.openstack.org/p/Cyborg-FPGA-Support-for-Cloud-NFV | |
| 14:31:14 | Sundar | One of the main conclusions is that the model where VM issues programming requests (what we called run-time programming) is important | |
| 14:31:27 | Sundar | However, we do not have a good end-to-end flow for that today. | |
| 14:31:44 | Sundar | This is an open question that we should address. | |
| 14:32:11 | Li_Liu | The main concern is who to trigger the programming right? | |
| 14:32:57 | Sundar | That is one of the main concerns, the other being the validity of the bitstream itself | |
| 14:33:11 | Li_Liu | ah, that one | |
| 14:34:15 | Sundar | For example, if a developer is developing new RTL inside the VM, the resulting bitstream may have bugs. Can that compromise the shell logic? Can it result in local hot spots or other power issues that affect the FPGA chip itself? | |
| 14:35:06 | Sundar | I was hoping to get feedback from operators on how they plan to validate bitstreams. Has Huawei considered that question? | |
| 14:35:45 | Li_Liu | in terms of operation, shall we 1. let this rtl be synthesis in a wel controlled environment. 2. Let this bitstream load on a clean room enviroment first | |
| 14:36:07 | Li_Liu | actually, internally, we did have some discussion | |
| 14:36:57 | Li_Liu | for now, we might not care too much about it as most of the IPs are in house developed | |
| 14:37:18 | Li_Liu | but in the case of letting 3rd party do the development | |
| 14:37:41 | Li_Liu | I think at lease 1. let this rtl be synthesis in a well controlled environment. is needed | |
| 14:38:49 | Sundar | If the environment is well-controlled, the bitstream may still have bugs. So, it is necessary but not sufficient. | |
| 14:40:17 | Sundar | Re. "Let this bitstream load on a clean room enviroment first", that is a good idea. So, do we confine bitstream development to bare-metal instances, so that a tenant can affect only himself or the local FPGA? | |
| 14:40:27 | Li_Liu | yes, that's why the 2nd point is also needed | |
| 14:41:46 | Li_Liu | it depends, it might just be a VM with a entire bitstream. The cloud provider should provide a CI/CD framework for such dev work | |
