building-notes: Note how to use cgroup for limiting resource usage We were saying "-jN means using N cores (or N threads)". This is completely wrong. "-jN" only tells the building system to run N jobs simultaneously, but each job can start their own subprocesses or threads and there is no way for the building system to know how many subprocesses or threads a job will start. This caused a lot of misunderstandings and encouraged users to wrongly blame building systems. Fix the description of -jN, and add how to use cgroup to control the usage of CPU cores and system RAM. On a systemd-based system, systemd is the cgroup manager and manually operating on cgroups may puzzle systemd. So use systemd-run for creating and setting up cgroup. On a sysv-based system create and set up the cgroup manually. 2023-09-19 02:17:29 +08:00			`<!DOCTYPE note PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"`
