| 13:36:13 | fried_rice | leakypipes: Gooood morning. | |
| 13:37:28 | cdent | edleafe: a while back you were thinking hard about https://bugs.launchpad.net/nova/+bug/1719933 . Did you make any conclusions? Should we bother, or can we kill that bug? | |
| 13:37:30 | openstack | Launchpad bug 1719933 in OpenStack Compute (nova) "placement server needs to retry allocations, server-side" [Medium,Triaged] - Assigned to Jay Pipes (jaypipes) | |
| 13:37:34 | fried_rice | leakypipes: Let me know when's good to do that aggregate distance talk. I'm free for the next hour, and then from 11-4 ET | |
| 13:37:35 | cdent | I guess you left a thing on the PTG etherpad. | |
| 13:37:56 | cdent | moin | |
| 13:41:53 | leakypipes | fried_rice: let's do 11am | |
| 13:42:06 | fried_rice | leakypipes: Roger that. | |
| 13:42:42 | fried_rice | cdent, edleafe, stephenfin, cfriesen, sean-k-mooney: ^ FYI. I'll be taking notes and writing something up after the fact in any case. | |
| 13:43:22 | cdent | fried_rice++ | |
| 13:43:57 | sean-k-mooney | fried_rice: just read scoll back | |
| 13:44:16 | sean-k-mooney | * reading | |
| 13:44:48 | fried_rice | sean-k-mooney: Not much scrollback - I'm going to get a brain dump from leakypipes on "modeling [anti-]affinity via aggregate distance" in 2.25h | |
| 13:45:14 | bauzas | oh fuuuuuu | |
| 13:45:15 | sean-k-mooney | Ah ok | |
| 13:45:21 | bauzas | Friday FTW | |
| 13:45:29 | fried_rice | sean-k-mooney: This is related to our NUMA discussions the other day, so I tagged you cause you might be interested to join. But if not, I'll be producing something written for you to consume after. | |
| 13:46:50 | sean-k-mooney | i would definetly like to understand how aggregate distance works as i only understand the distance along the tree approch and dont know how to connect the 2 or even if they are compatible | |
| 13:47:23 | openstackgerrit | Lee Yarwood proposed openstack/nova stable/pike: Encode libvirt domain XML in UTF-8 https://review.openstack.org/542831 | |
| 13:47:43 | sean-k-mooney | fried_rice: also i still own you some advanced flavours | |
| 13:48:11 | fried_rice | sean-k-mooney: Heh, yeah, that pastebin from the other day is still on my pile to look at and quiz you about. | |
| 14:05:53 | figleaf | cdent: re: https://bugs.launchpad.net/nova/+bug/1719933 - we agreed that the issue is more complex than simply retrying, hence the PTG discussion | |
| 14:05:55 | openstack | Launchpad bug 1719933 in OpenStack Compute (nova) "placement server needs to retry allocations, server-side" [Medium,Triaged] - Assigned to Jay Pipes (jaypipes) | |
| 14:07:09 | cdent | thanks figleaf. I couldn't remember if there wasn't perhaps a chance for a "meh, nevermind" | |
| 14:07:54 | figleaf | fried_rice: 10am CST? | |
| 14:08:05 | fried_rice | figleaf: Yes | |
| 14:08:11 | figleaf | cdent: it may very well end up being "meh" | |
| 14:08:35 | figleaf | fried_rice: I can join the discussion at that time | |
| 14:08:44 | fried_rice | coo | |
| 14:13:29 | figleaf | cdent: I added a comment to that bug in case anyone else has memory issues | |
| 14:13:40 | cdent | thanks | |
| 14:39:41 | finucannot | fried_rice: Sure thing. If you want, ping me beforehand so I don't forget :) | |
| 14:39:51 | openstackgerrit | Matt Riedemann proposed openstack/nova stable/pike: doc: fix the link for the evacuate cli https://review.openstack.org/542856 | |
| 14:39:54 | fried_rice | finucannot: Will do | |
| 14:42:11 | hrw | mriedem: morning | |
| 14:42:12 | fried_rice | sean-k-mooney: What's the proper terminology to say that a NIC (or pf) is "in" a given NUMA node? | |
| 14:43:03 | fried_rice | sean-k-mooney: So like, a NUMA node encompasses a certain portion of the system's CPUs and RAM, and also there's some kind of bus connection to NIC slots that makes it more efficient to use that NIC than the other. | |
| 14:45:07 | sean-k-mooney | fried_rice: generally we say the nic has a numa affinity to numa node x | |
| 14:45:16 | fried_rice | sean-k-mooney: Thanks | |
| 14:46:22 | sean-k-mooney | fried_rice: what that actully means is for a DMA or MMIO capable device the memory adress allocated to that device are from the adress range associated to numa node X | |
| 14:46:33 | fried_rice | sean-k-mooney: Dig | |
| 14:48:08 | fried_rice | Is master Rocky now? | |
| 14:48:10 | fried_rice | mriedem: ^ | |
| 14:48:23 | sean-k-mooney | cpus get numa affinity because they are phyically closer to one memory controler then the rest. so address form that controler(numa node) can be loaded into cache faster then form a remote numa node | |
| 14:48:45 | fried_rice | sean-k-mooney: Phew, that gels with my (admittedly extremely limited) understanding. | |
| 14:49:41 | fried_rice | sean-k-mooney: And for PCI devices, there's something about the bus that goes to that particular I/O slot that makes the same kind of communication faster. | |
| 14:50:53 | sean-k-mooney | kindof, each socket on a modern system(e.g. it does not have a front side bus) has a pci controler route | |
| 14:51:23 | sean-k-mooney | each pci slot is phyically wiered to a partcalar pci controer/socket | |
| 14:51:43 | sean-k-mooney | so the pci slots on a mother board have socket affintiy | |
| 14:52:11 | sean-k-mooney | with processors with only one memory controler they have numa afinity too | |
| 14:53:01 | sean-k-mooney | with processors with 2 memory controlers teh numa affinity is determined by what memory controler the kenerl allocates the mmio address form for that device | |
| 14:53:16 | fried_rice | Okay, I said 'bus' but I guess I meant 'socket'. I'm a hardware 'tard. | |
| 14:53:30 | sean-k-mooney | linux puts all pci devices on the first memory controler/numa node on a socket by default | |
| 14:55:17 | sean-k-mooney | fried_rice: working at intel i kindof have to know these things but its all a little archane | |
| 14:56:50 | openstackgerrit | melissaml proposed openstack/nova master: fix typos https://review.openstack.org/542866 | |
| 15:14:15 | mriedem | fried_rice: yes master is rocky since we have a stable/queens branch now, however, we likely don't want to land any major changes that are big refactors or delete code until we've fully released queens, because of backports for rc2 if we need them | |
| 15:14:17 | mriedem | hrw: hi | |
| 15:14:40 | fried_rice | mriedem: Roger wilco, thanks. | |
| 15:17:54 | mriedem | melwitt: i've updated launchpad to point rocky as the dev focus, and created the rocky milestones https://launchpad.net/nova/rocky | |
| 15:18:05 | mriedem | based on https://releases.openstack.org/rocky/schedule.html#r-release | |
| 15:18:19 | melwitt | mriedem: cool, thank you | |
| 15:18:27 | mriedem | i'll create a queens-rc2 milestone if we end up having one https://launchpad.net/nova/queens/ | |
| 15:25:06 | mriedem | lyarwood: want to hit https://review.openstack.org/#/c/542323/ ? | |
| 15:26:12 | openstackgerrit | Stephen Finucane proposed openstack/python-novaclient master: Remove 2 redundant methods https://review.openstack.org/528325 | |
| 15:30:37 | lyarwood | mriedem: ack done | |
| 15:35:59 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Poison context usage in periodic tasks https://review.openstack.org/542891 | |
| 15:39:40 | openstackgerrit | Balazs Gibizer proposed openstack/nova master: Poison context usage in periodic tasks https://review.openstack.org/542891 | |
| 15:49:57 | hrw | mriedem: went through your comments and pushed update to https://review.openstack.org/#/c/541728/ | |
| 15:50:23 | hrw | mriedem: one of our team members will check for me entries I skipped | |
| 15:51:05 | leakypipes | fried_rice: can you give me another 30 mintues? | |
| 15:51:13 | fried_rice | leakypipes: Okay. | |
| 15:51:20 | fried_rice | leakypipes: Whyncha ping me when ready? | |
| 15:51:33 | leakypipes | fried_rice: yeah, thanks man | |
| 15:55:31 | openstackgerrit | Merged openstack/nova master: Ensure the JSON-Schema covers the legacy v2 API https://review.openstack.org/540154 | |
| 16:02:59 | bauwser | meh, one day without being upstream | |
| 16:03:01 | bauwser | sad. | |
| 16:07:14 | leakypipes | fried_rice: https://etherpad.openstack.org/p/going-the-distance | |
| 16:07:57 | leakypipes | fried_rice: I'm ready when you are. | |
| 16:08:27 | fried_rice | leakypipes: Okay, we gonna go through this or should I pre-read? | |
| 16:08:43 | edleafe | fried_rice: it'll take an hour to read :) | |
| 16:09:06 | leakypipes | fried_rice, edleafe: please spend some time to read and then let's get on a hangout? | |
| 16:09:16 | fried_rice | finucannot, sean-k-mooney, edleafe, cfriesen: Heads up, we're gonna do this thing soon. | |
| 16:09:20 | fried_rice | leakypipes: Roger that. | |
| 16:09:41 | edleafe | leakypipes: can I clear the pink color? | |
| 16:11:05 | leakypipes | edleafe: yessir, absolutely. | |
| 16:11:20 | edleafe | ah, much easier on the eyes | |
