Vladimír Čunát | sleepy-brown: now I simply changed its --jobs from 8 to 4. I needed to restart at least a dozen kernel builds in the past few days, always out-of-space on /tmp. | 06:44:44 |
Vladimír Čunát | For a longterm solution, I'm not convinced that /tmp on tmpfs is worth the trouble. | 06:45:35 |
hexa | increased tmpfs to 160GB 14 hours ago | 13:47:49 |
@emma:rory.gay | what even is the point of /tmp on tmpfs in this case? reserving disk space for built derivations? | 23:34:32 |
hexa | higher throughput because we are building in memory | 23:35:31 |
@emma:rory.gay | ah, i guess that makes sense | 23:35:52 |
hexa | less wear on the disks | 23:35:53 |
@emma:rory.gay | im guessing that comes with the downside of being more expensive, due to memory usage? | 23:36:32 |
hexa | increased to 6, because 40G per job on average is hopefully fine | 23:36:50 |
@emma:rory.gay | * im guessing that comes with the downside of being more expensive, due to memory usage?
aka needing nodes with more ram | 23:36:54 |
hexa | big compute generally comes with sufficient ram | 23:37:13 |
hexa | this is mostly about source trees that expand to a large footprint, and then many of these in parallel | 23:37:51 |
hexa | right now for example
22G nix-build-rocblas-6.0.2.drv-0
| 23:38:43 |
hexa | but also chromium, electron, the linux kernel | 23:39:15 |
@emma:rory.gay | i thought the kernel was some 4 gigs? | 23:39:26 |
@emma:rory.gay | and im guessing there's some kind of compartimentalisaion going on? (ie. one node for a few large builds, one node for many smaller builds in parallel) | 23:41:10 |
hexa | big-parallel is the tag for large builds | 23:42:05 |
@emma:rory.gay | ah, guessing not all builders have that tag set then | 23:42:45 |
