Fixes <https://issues.guix.gnu.org/43773>. The computed normalized load was previously obtained by dividing the load average as found in /proc/loadavg by the number of parallel builds defined for a build machine. This normalized load didn't allow to compare machines with different number of cores, as the load average reported by /proc/loadavg can be as high as the number of cores; thus comparing that value to a fixed threshold of 2.0 would mean machines with multiple cores were more likely to be flagged as overloaded compared to single core machines. This can be fixed by normalizing using the available number of cores instead of the number of parallel jobs. * guix/scripts/offload.scm (<build-machine>)[overload-threshold]: New field. (node-load): Modify to return a normalized load value between 0 and 1, taking into account the number of cores available. (normalized-load): Remove procedure. (report-load): New procedure. (choose-build-machine): Adjust to use the modified 'node-load' and the new 'report-load' and 'build-machine-overload-threshold' procedures. (check-machine-status): Adjust. * doc/guix.texi (Daemon Offload Setup): Document the offload scheduler and the new 'overload-threshold' field. |
