**** BEGIN LOGGING AT Thu Feb 13 02:59:57 2020 Feb 13 08:27:22 JaMa: I'm rebuilding the failed tests, so I have a full set and will PR my results Feb 13 08:27:47 Had no chance for BIOS update or memtest yet due to being out yesterday evening, maybe tonight Feb 13 09:16:20 JaMa: Seems I keep getting ICE on the all-cores build Feb 13 09:57:52 Morning Feb 13 10:55:25 Herrie: yeah all-cores is the worst, also did we clear that you had enough swap? Yesterday I was reading longs from colleague who has some fast workstation, but not with so many cores as you and it was triggering OOMK with 64G ram and 64G swap Feb 13 10:56:10 Herrie: which in his case was recognizable from the log as gcc being killed (not ICE), but depending on what OOMK really kills it might be an ICE as well I believe Feb 13 10:59:22 JaMa: Not sure if have SWAP setup at all tbh Feb 13 10:59:25 How can I check again? Feb 13 10:59:36 Just mount to see if there's some swap mounted? Feb 13 12:17:58 free -g is the easiest or swapon --show Feb 13 12:47:05 JaMa: OK, seems my builder locked up :S Feb 13 13:00:54 maybe it's too busy to respond to ssh and it will get back online once it finishes some part of build or gets killed by OOMK Feb 13 13:01:23 I got locked up on 1600AF as well when it had less swap Feb 13 13:04:50 It didn't last time, only hard reset helped then Feb 13 14:05:37 Seems my SWAP is 2GB, I guess it could be a bit bigger? Not sure what's recommended size? Feb 13 15:34:57 JaMa: Retrying with 32GB SWAP now Feb 13 16:05:30 Herrie: FYI 3990x results: https://github.com/shr-project/test-oe-build-time/pull/2 Feb 13 16:06:22 Herrie: your builder is really fast, but this is insane Feb 13 16:06:36 err this is just 3970x.. 3990x will come later Feb 13 16:27:44 JaMa: Well there's always bigger & better ;) Feb 13 16:27:54 Value for money mine isn't doing bad ;) Feb 13 16:28:31 3990X should blow away everything else probably ;) Feb 13 16:29:54 Unless you go dual Epyc but that's a different price category in itself ;) Feb 13 16:30:10 Cheapest Epyc CPU is more expensive v.s. my whole system ;) Feb 13 16:43:58 JaMa: So far it seems to behave better with bigger swap, but still webengine etc to build Feb 13 19:09:37 JaMa: All cores succeeded now, 8 cores is running still so could've been too small SWAP? Feb 13 19:09:53 Bit weird I would get ICE though Feb 13 20:08:42 8 threads still running, but so far so good. Now busy with qtwebengine Feb 13 20:11:32 70 more tasks after this and it's done Feb 13 21:04:06 JaMa: PR-ed my results :) Feb 13 21:13:42 JaMa: What you plan to do with the results in general? Decide on what to buy for a new builder :P ? Feb 13 21:42:05 Herrie|2: yes, I'm looking for new builder, the servers at work are rather old and IT is bugging me to shut them down as they are not worth the power they are using Feb 13 21:42:36 Herrie|2: which seems to be the case for dual-Xeon-E5-2670-8-channels I have in the table Feb 13 21:43:51 But system with single socket Epyc 7702P is less than 10% more expensive than 3990X and both are more than twice expensive than 3970X Feb 13 21:45:06 I think IT wouldn't be happy to buy me single and dual Epyc + 3990X and 3970X for tests, so I was quite happy when wendell mentioned that he is looking for some reproducible work loads to test these machines :) Feb 13 21:47:37 The main disadvantage of 7702P Epyc is that there aren't (m)any "workstation-like" motherboards, like E-ATX where you have normally placed PCIE for GPU, cooling on VRM and bunch of SATA+NVMe (without need to deal with miniSAS to SATA cables etc Feb 13 21:48:02 and if you find one, then it probably won't be available anywhere close (and even worse to be in stock) Feb 13 21:48:32 while TRX40 boards are plenty, with nice features and some bonuses like PCIE for 4 NVME drives etc Feb 13 21:50:50 but from raw performance view everything is better on Epyc, 8 memory channels (which might make tmpfs feasible while 128 threads are hammering the memory with the build itself) and 16 memory slots supporting RDIMM/LRDIMM instead of TRX40 which has only 8 slots and only UDIMM (faster 8x32GB kits are also hard to find, g.skill announced them 3-4 times already, last news is that probably 2Q 2020) Feb 13 21:51:11 https://www.gskill.com/community/1502239313/1581390195/G.SKILL-Announces-High-Performance,-High-Capacity-DDR4-3600-C16-256GB-(32GBx8)-Memory-Kit Feb 13 21:52:02 https://www.gskill.com/community/1502239313/1574739775/G.SKILL-Announces-New-High-Performance,-Ultra-Capacity-DDR4-Memory-Kits-for-HEDT-Platforms Feb 13 21:52:24 https://www.gskill.com/community/1502239313/1570624595/G.SKILL-Releases-New-DDR4-32GB-Module-Specs-with-Memory-Kits-Up-to-256GB Feb 13 21:54:09 Ah OK well I use it just for LuneOS and Halium so way overkill really but should serve me well for a while Feb 13 21:54:45 And it replaced 2 power hungry machines at my end so in terms of energy usage it probably improved things Feb 13 21:55:04 SP3 boards https://www.gigabyte.com/cz/Server-Motherboard/MZ32-AR0-rev-10#ov https://www.asus.com/cz/Commercial-Servers-Workstations/KRPA-U16/ https://www.tyan.com/Motherboards_S8030_S8030GM4NE-2T https://www.asrockrack.com/general/productdetail.asp?Model=ROMED8-2T#Specifications but hard to buy (in small quantities) Feb 13 21:55:19 And I went from Windows desktop and Ububtu builder to a single KUbuntu machine Feb 13 21:56:03 yes, yours is still really nice (and still quite expensive) Feb 13 21:56:46 I've added some tables and spreadsheet to the git repo, but before your PR, so will add yours shortly Feb 13 21:57:40 Yeah it was around EUR 5000 I think altogether Feb 13 21:57:55 Also due to the 2* 10GB storage though Feb 13 21:59:17 interesting part is that single 3970X beats dual Xeons from 2014 by quite a big margin, so buying used server for OE builds doesn't look like good option anymore **** ENDING LOGGING AT Fri Feb 14 02:59:59 2020
