Re: confine user(s) to a core with systemd + gcgroup

Just a curiosity question: If you segregate a user to just one CPU core, does that really save a system from being crippled if they max out that core, or crash it? I'd have thought that the rest of the system would still be affected to some degree. At the least, it'd have to be completely isolated from the user's core. And it strikes that me that a user using the operating system isn't isolated, they interact with it. -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
