|---|---|---|
| oneswig | Cool, what's in it? | 20:58 |
| martial | help | 20:58 |
| martial | (oops too many keyboards) | 20:59 |
| oneswig | IRC's famous user-friendliness! | 20:59 |

| oneswig | Let's get this show on the road. | 21:00 |
| oneswig | #startmeeting scientific-sig | 21:00 |
| openstack | Meeting started Tue Jan 5 21:00:14 2021 UTC and is due to finish in 60 minutes. The chair is oneswig. Information about MeetBot at http://wiki.debian.org/MeetBot. | 21:00 |

| *** openstack changes topic to " (Meeting topic: scientific-sig)" | 21:00 | |
| openstack | The meeting name has been set to 'scientific_sig' | 21:00 |
| *** julian1 is now known as julianp | 21:00 | |
| martial | 32 cores, 128GB mem and an Nvidia GPU | 21:00 |
| oneswig | Thanks for the reminder Martial, was just watching "agents of shield" with young sir. | 21:00 |
| oneswig | Is that like a Jetson Nano? | 21:01 |
| oneswig | Or are these beefy x86 cores? | 21:01 |
| martial | well it might be a quiet meeting and you can get back to it soon | 21:01 |
| martial | beefy cores: AMD 5950x 16 cores, 32 "threads" | 21:01 |
| oneswig | Sounds like a new gaming rig :-) | 21:02 |
| oneswig | So what else is new? | 21:02 |
| martial | well yes, that too ;) | 21:02 |
| trandles | Hi all. Sorry I'm late | 21:02 |
| martial | here not much, end of the year time | 21:03 |
| martial | welcome Tim | 21:03 |
| jmlowe | Tim Randles is never late, he arrives exactly when he means to | 21:03 |
| martial | and Jim :) | 21:03 |
| oneswig | Hey guys, happy new year | 21:03 |
| jmlowe | Same to you | 21:05 |
| martial | Happy new year :) | 21:05 |
| julianp | Ditto. | 21:05 |
| oneswig | OpenStack-themed resolutions for 2021? | 21:05 |
| trandles | Absolutely: Full production cloud in H1C21 | 21:05 |
| trandles | Ironic for all HPC-owned system provisioning and deployment (it's looking like I might win that battle) | 21:06 |
| jmlowe | same for me actually | 21:06 |
| oneswig | Awesome | 21:06 |
| jmlowe | production in H1C21 | 21:06 |
| julianp | Ooh! | 21:06 |
| trandles | A colleague has been working on OpenShift-on-OpenStack. Mixed results so far. | 21:06 |
| oneswig | What's the mix? I'd have thought that would work out of the box | 21:07 |
| trandles | But we're about to have paid RHAT support for that config soon, so the issues we're having might go away sooner than later. | 21:07 |
| trandles | In meetings with RHAT they will support OpenShift-on-OpenStack but they seem to feel it's a little more bleeding edge than OpenShift on VMWare or RHV or bare metal | 21:08 |
| trandles | more info as we get it | 21:09 |
| oneswig | surprising inversion against their own infrastructure product | 21:09 |
| oneswig | I think for me my first resolution is to do a lot more about CI. Again. | 21:09 |
| julianp | oneswig: Does that refer to Continuous Integration? | 21:10 |
| trandles | RE: CI - one of our projects just switched from travis to github actions and they're really happy with it. | 21:10 |
| oneswig | This time we are really going to do it :-) julianp: yes - regression testing, builds, all that jazz. | 21:10 |
| julianp | Righto. | 21:11 |
| julianp | trandles: I've heard similar happy stories about GitHub Actions. | 21:11 |
| oneswig | Typically we've used whatever's available, got a jack-of-all-trades experience with different CI frameworks | 21:11 |
| oneswig | jmlowe: when does your hardware show up? | 21:12 |
| jmlowe | Looking more and more like beginning of April | 21:13 |
| oneswig | Ah, that's a bit of slippage, too bad | 21:13 |
| trandles | Do you know what's causing the delay jmlowe ? | 21:14 |
| trandles | Any specific component? | 21:14 |
| jmlowe | Between NVIDIA redstone boards and Milan, I think we are looking at about 6 weeks later than expected | 21:14 |
| *** manpreet has quit IRC | 21:15 | |
| oneswig | Maybe there will be a working pip by then :-) Been having troubles with the new dependency resolver today, never completing. | 21:16 |
| trandles | Curious because the tri-labs are working on a new round of commodity systems. I think we were hoping to start taking deliveries late summer, but no contracts are awarded or anything. I have no idea if "NVIDIA redstone boards and Milan" will matter or not. | 21:16 |
| oneswig | HPC clusters, private clouds or somewhere between the two trandles? | 21:18 |
| jmlowe | Are you getting non DGX A100's (redstone)? Are you planning on AMD Milan chips? If the answer is no then it's not a concern | 21:18 |
| martial | serious setup, all this | 21:19 |
| trandles | HPC clusters | 21:19 |
| jmlowe | 7 to 8 figure price tags | 21:20 |
| oneswig | If Livermore's one of the Tri-labs, I spent some happy weeks cabling HPC clusters with Quadrics interconnect. Such a tidy sub-floor :-) | 21:21 |
| trandles | So LANL/LLNL/SNL purchase common commodity tech HPC clusters. It's something like "We will buy X scalable units and we want an option to by Y more, over the next 3-5 years." | 21:21 |
| trandles | *buy Y more* | 21:21 |
| trandles | the last round was from Penguin Computing | 21:22 |
| trandles | Intel procs, OPA interconnect | 21:22 |
| trandles | NVIDIA GPUs for those who want them | 21:22 |
| jmlowe | I can't imagine that went too well | 21:22 |
| jmlowe | Or did you get the world's first solid OPA interconnect? | 21:23 |
| trandles | It went ok. We have ~10000 nodes total across a bunch of discrete clusters | 21:23 |
| trandles | OPA has been ok. | 21:23 |
| trandles | Once we got rid of gobs of bad cables | 21:23 |
| oneswig | I'll be fascinated to see how the spin-off company wanting to revive it works out | 21:24 |
| oneswig | trandles: have you spoken to Penguin about Ironic for provisioning? | 21:25 |
| trandles | oneswig: nope | 21:26 |
| oneswig | I wonder how flexible their Penguin-on-demand service is. | 21:26 |
| martial | DMC has had success with Linode but our use case is once again specific | 21:29 |
| oneswig | Not tried Linode before. | 21:30 |
| trandles | I've never used Penguin on-demand. 10+ years ago when I was in a uni physics department they pitched it HARD to the faculty. | 21:30 |
| jmlowe | We hosted one of the PoD racks for a few years in our data center | 21:32 |
| jmlowe | It's a losing business model, people just don't have opex just capex | 21:33 |
| jmlowe | and it's nearly impossible to covert | 21:33 |
| oneswig | Perhaps another resolution is to get to grips with ceph orchestrator. We've got an Ansible role taking shape to drive it from yaml data, so it fits better into a sane deployment process. | 21:34 |
| julianp | o/ | 21:38 |
| *** ircuser-1 has quit IRC | 21:38 | |
| oneswig | martial: DMC must be a big user of linode, it's made a case study - https://www.linode.com/spotlight/data-machines-brian-dennis/ | 21:39 |
| martial | yes, like I said very specific use case; GPU for one of our ML project | 21:39 |
| martial | and that is a burst on top of our Data Center hardware | 21:40 |
| oneswig | martial: interesting. How do you share the datasets in this hybrid model? | 21:41 |
| martial | happy to ask Brian if he can talk about it directly at a follow up meeting if that would be of interest to the group | 21:41 |
| *** cmart has joined #openstack-meeting | 21:42 | |
| oneswig | sounds good to me | 21:42 |
| martial | will reach out ... maybe the next USA friendly meeting if he is able to | 21:42 |
| oneswig | cool | 21:43 |
| martial | slack-ing him right now | 21:44 |
| julianp | Hello cmart! | 21:45 |
| cmart | howdy. joining from Matrix, appears to be working | 21:46 |
| martial | We can host a google meet like the presentation Rion did a while back | 21:46 |
| oneswig | sounds good | 21:46 |
| oneswig | julianp: what's new with you? | 21:48 |
| julianp | Quite a bit. Lots of irons in the fire. | 21:49 |
| julianp | cmart implemented a mechanism to white label Exosphere, and Jetstream has a beta version now. | 21:50 |
| julianp | https://exosphere.jetstream-cloud.org/ | 21:50 |
| oneswig | white label? | 21:50 |
| julianp | Customizing the theme. Colors, logos, etc. | 21:51 |
| julianp | This file is all that's required to make the Jetstream version: https://exosphere.jetstream-cloud.org/exosphere/config.js | 21:51 |
| oneswig | ah, ok. Intersting | 21:51 |
| julianp | No recompilation required. Just works. | 21:52 |
| julianp | And since there are no services required for Exosphere to work (other than some CORS proxies) it's easy to provide a customized version. GitHub pages is sufficient to host it. | 21:54 |
| oneswig | I wonder if this could ever work with OAuth2, in theory. Just feel a little uneasy about typing my credentials into somebody else's portal. | 21:55 |
| cmart | we actually need to build that in the next few months, oneswig | 21:55 |
| oneswig | ooh, now that would be neat. | 21:55 |
| cmart | the answer is probably yes, Keystone has support for OpenID connect on top of OAuth | 21:55 |
| cmart | if you go to https://iu.jetstream-cloud.org/ you'll see an option for "OpenID Connect", and it will take you to Globus to authenticate yourself | 21:56 |
| cmart | jmlowe: | 21:56 |
| oneswig | Very nice. | 21:56 |
| cmart | jmlowe set it up a few weeks ago | 21:57 |
| cmart | the idea is that exosphere can tickle the same Keystone endpoint that Horizon does to make this work | 21:57 |
| julianp | oneswig: What's the eta on your ironic cloud for public good projects? | 21:58 |
| oneswig | That's where the Ceph work's going on currently... Not sure on an ETA, but early access friends welcome perhaps in a few weeks | 21:59 |
| cmart | (also small nitpick, it's not "somebody else's portal" anymore, see the subdomain of jetstream-cloud.org :D ) | 21:59 |
| oneswig | cmart: got it :-) I was mostly thinking of the trial site | 22:00 |
| oneswig | ah, we are out of time. Any more comments? | 22:00 |
