As far as I understand, Linux supports that through Cgroups, specifically, quoting: http://docs.fedoraproject.org/en-US/Fedora/15/html/Resource_Management_Guide/sec-cpuacct.html cpuacct.usage_percpu reports the CPU time (in nanoseconds) consumed on each CPU by all tasks in this cgroup (including tasks lower in the hierarchy).
