oneswigHi TheJulia, welcome!21:01
oneswigears burning? :-)21:01
oneswigmartial: you there?21:02
trandlesHi all21:02
oneswigHi trandles21:02
martialyes Hi :)21:02
oneswig#chair martial21:02
openstackCurrent chairs: martial oneswig21:02
TheJuliaoneswig: no, not really burning :)21:02
oneswigawesome, well let's talk kexec...21:03
oneswig#topic Ironic deploy and kexec21:03
*** openstack changes topic to "Ironic deploy and kexec (Meeting topic: scientific-sig)"21:03
oneswigcontext on this is that BIOS is sometimes just too damn slow to endure a second lap on deployment21:04
oneswigIn some circumstances, we are measured by the time taken to deploy / redeploy n servers where n is uncomfortably large.21:04
TheJuliaI've wanted to see this be a thing in ironic for quite some time. However I simply don't have time to make it happen on my own. I've got some patches, and I'm happy to hack on patches occasionally, but could really use some help with at least some reviews and testing.21:05
TheJuliaSo in our midcycle call this week, the topic came up of trying to get a smallish working group together of interested parties to collaborate and try and push it over the finish line.21:05
TheJuliaThe added bonus of which, being able to influence use cases/operation and such21:06
oneswigTheJulia: I hope someone from our team can help.  Worst case, its me...21:06
trandlesI'm on board for testing/review/QA21:06
TheJuliaThat would be awesome!21:06
TheJuliaAnyway, I created a quick dooddle with some time windows to try and see if we could get on a call to discuss.21:07
TheJulia#link https://doodle.com/poll/ihbbtns36b2rkhfd21:07
TheJuliaI guess that is kind of it unless there are questions/comments/thoughts/wants/etc21:08
* TheJulia adds needs to that list21:08
oneswigGreat.  Where are you at with your patches?21:08
TheJuliaoneswig: need rebasing, they haven't been tested, more so just trying to get the idea out of my head21:10
oneswigOne other thought - is this compatible with multi-tenant networking, or are they mutually exclusive due to the shortcuts taken?21:10
TheJuliamostly to see the areas where things would tie in21:10
TheJuliamulti-tenant networking would need tobe something we consider since it is another path. It might be feasible but we may jsut need to be able to tell ironic's agent to "go kexec in 15 seconds"21:11
TheJulianaturally there is also greater risk there, but we're at the stage where discussion of such needs/wants/concerns/thoughts/desires are important21:12
oneswigIt does seem tricky...21:13
TheJuliaYeah, I also kind of want to see kexecing from a persistent agent as well, so it does lend itself to needing to being able to navigate multiple paths21:13
*** slaweq has quit IRC21:14
oneswigSorry What do you mean by persistent agent?21:14
TheJuliaAnd yes, I'm thinking some operators could go from a deployed workload, to deployment ramdisk, to another workload without an actual reboot in such a case21:14
trandlesI'm hoping standalone is the easiest case and where the work starts (mostly because that's the one I need)21:15
oneswigOK - wow, interesting idea.21:15
TheJuliathere has been some community interest in trying to eventually make ironic's agent such that it could live inside an instance and eventually tear down the node from with-in. Naturally there are other concerns there that would need to be navigated, but it is a neat concept of sorts21:15
TheJuliatrandles: ++21:15
oneswigTheJulia: what's the feature deadline for Victoria?  Too soon?21:18
TheJuliaIt is very unlikely to make Victoria. If there is enough interest it should make our first release after the end of victoria cycle release21:18
TheJuliaof course, if people are really interested and want to focus on it, maybe we might be able to make things happen in a couple weeks21:19
oneswigThat would be a stretch at this end.21:19
TheJuliaUnfortunately I lack a time machine to go collect the code from the future as well...21:19
* TheJulia hopes someone got a chuckle out of that21:20
oneswigI would lend you mine but Trump borrowed it and hasn't given it back...21:20
trandlesI'll expedite figuring out the upstream stuff so I can at least review in a meaningful way21:20
TheJuliaoneswig: DOH!21:20
TheJuliatrandles: I'd be happy to jump on a call and kind of try to walk you through that if you want21:21
trandlesif Trump is working on future knowledge we're all doomed...nevermind TheJulia we won't need kexec21:21
oneswigThe tangled webs we weave.21:21
TheJuliasilly paradoxes :(21:22
trandlesTheJulia: thanks for the offer. I'll ask for help if I get stuck.21:22
oneswigTheJulia: will you announce the kexec-wg meeting on openstack-discuss? I'll keep an eye out if so.21:22
TheJuliaoneswig: I will, and I'll send a calendar invite out to participants if I have their email addresses21:24
TheJuliaor can find them21:24
oneswigsounds good to me.  Thanks TheJulia21:24
oneswigOK - any more on kexec?21:26
TheJuliaNot from me, thanks!21:27
oneswigGreat, thanks for coming along TheJulia21:27

trandlesno particular theme that I know of, quite a broad scope at https://www.canopie-hpc.org/cfp20/21:31

trandlesthat is a topic I'd love to hear more about, not just debuggers but analysis tools like tau, stat, etc.21:33
trandlesit's on my own internal hot list of things the community needs to get a handle on and develop some best practices21:34
martialDeadline has been extended to 9/1021:34
trandlesalso best practices for containerized MPI applications at scale21:35
trandlesCharliecloud has spoiled me, other runtimes are painfully horrible at that21:35
oneswigWhat's new with Charliecloud?21:36
trandlesunpriviledged build21:36
trandlestotally unprivileged, no setuid nonsense21:36
trandlesalso on the near term roadmap, multi-stage builds21:37
trandlesbetter support for `spack containerize`21:37
trandlesthere are lots of other things but maybe not of general interest...like all containers are read-only and if you application can't handle that you're doing it wrong21:40
oneswigOn a tangent we've had huge problems building and running WRF with any semblance of portability.  I'd buy so much beer for someone who could containerise it in a way that works.  Unfortunately it's a mutant in that the data model somehow gets compiled into the code.  You think you've got badly-behaved applicatoins :-)21:41
trandles*your appliction*...geesh21:41
trandlesI'm not familiar with WRF21:41
trandlesoh, weather, nevermind21:41
oneswigweather code.  When we have a client who wants it, it's always a stormy forecast21:42
trandlesI'll buy you a beer for that one ;)21:42
oneswigtrandles: do you use the tau visualization tool?21:43
trandleswe do21:43
trandlesbeyond that, it's far from my area21:43

oneswigmust be a fascinating field to work in.21:45
trandleswe just had a tau workshop for users last week21:45
oneswigtheir example of visualising MPI_Alltoallv over 786432 cores ...21:47
oneswigSuch a shame they couldn't round up to the million21:48
martialhave you seen the new gaming GPU announced today?21:48
oneswigNo, what's new?21:49
trandlesRTX 3090?21:49
martialthey announced the 3070, 3080 and yes the 309021:50
martialwe all kind of knew it was coming :)21:50
martialbut it is a nice range of hardware21:50
martialthey announced a few other things, but the 3090 will have 24GB of memory21:51
martialif you want to see the announcement, here is the youtube link https://www.youtube.com/watch?v=QKx-eMAVK7021:51
martialno Ti this time21:52
oneswigSounds ideal for business graphics.21:53
martialyes it looks rather nice21:55
martialPerformance is 1.5 to 2 times faster than previous gen21:55
martialwhich is nice as well21:55
trandlesI could say "what's a GPU?" because other than my work laptop I don't have a computer at home. :P21:56
martialI should not start to count the number of computers in this room alone :)21:56
trandlesI use my phone for everything...which says a lot about the current state of HPC hardware :(21:56
*** Trevor_V has joined #openstack-meeting21:56
martialhey it works for what you need21:57
trandleswhen nvidia buys ARM I'm going to look into llama farming21:57
oneswigtrandles: those huawei phones are awesome :-)21:57
martialor one plus21:58
oneswigNearly at time - last gasp comments21:58
martialtrandles that is a plan21:58
martialoh right :)21:58
trandlesis the SIG submitting something?21:58
martial#topic PTG21:59
*** openstack changes topic to "PTG (Meeting topic: scientific-sig)"21:59
martialwe were planning to21:59
oneswigah yes.  I took an action two weeks ago to do something like last time.21:59
martialI know we discussed it21:59
trandlesmartial will do it, great, thanks Martial!21:59
martialdid I just walk into a trap?21:59
martialI am pretty sure Stig is mostly done :)22:00
oneswigA trap so subtle22:00
martialStig: did you do something or not?22:00
*** TrevorV has quit IRC22:00
oneswignp, I said I'd do the paperwork - I will sort it.22:00
martialI can take care of it, but not before next week22:00
martialwhat is the deadline?22:00
oneswig9th? 11th?22:00
oneswigI'll look into it tomorrow.22:01
oneswigtime to close22:01
martialthank you; ping me if you need help22:01
trandlesI'd do it but I'm busy working on containerizing WRF for oneswig. He offered beer.22:01
oneswigtrandles: you don't know what you're getting into, walk away22:01
martialhey ... the right priorities :)22:01
oneswigOK, thanks all22:01
