emily | Gaétan Lepage: x86 Linux builder is at >100% CPU usage | 16:15:30 |
Gaétan Lepage | Yes I'm building torch | 16:15:49 |
Gaétan Lepage | I can kill it. This is endless | 16:16:03 |
Gaétan Lepage | (I made sure to --max-jobs 1 --cores 0 so I hope the LAV is not over 24) | 16:16:36 |
emily | --max-jobs 1 --cores 0 will frequently make load average go > nproc | 16:17:55 |
emily | since the leaf build children are never the only process running on the system | 16:18:24 |
emily | * since the leaf build children are never the only processes running on the system | 16:18:33 |
emily | load average: 24.65, 25.85, 26.11 | 16:19:04 |
Gaétan Lepage | Is 25.5 (current 15min LAV) significantly worse than 24? | 16:19:40 |
Gaétan Lepage | I can set --cores n-1 next time if this makes a tangible difference. | 16:19:57 |
Max | make invocations that don't set `-l` are a crime against humanity | 16:20:08 |
emily | yes, an overloaded system thrashes endlessly and makes it take 10 seconds to fork a single command etc. | 16:22:26 |
emily | not that 23 is great either on a shared resource | 16:22:33 |
