Systemd will then take care of pinning the process to the named cores. Takes a space-separated list of CPU indexes. 3 is relevant only if converter logs in the source machine with an user other than 'root'. systemd provides CPUAffinity= directive that uses sched_setaffinity(2), there is no counterpart for set_mempolicy(2) though. If an operator is on a systemd managed platform, they may choose instead to set the CPUAffinity value for the root slice to the set of CPU cores that are reserved for the host processes. There are several VM operating parameters that can be set to improve system throughput for a single or multiple VMs installed on a KVM host. Helpful man files: systemd. 17 ENTER ['do'](['bash', '--login', '-c', '/usr/bin/rpmbuild -bs --target x86_64 --nodeps /builddir/build/SPECS/squid. This option may be declared multiple times. As to why it would keep restarting, no idea, you could try going systemd-only (maybe its to do with the initscripts compatibility code, though that's unlikely) or checking the logs at the point when cups is first started.
