(After a few hours of coding my brain hurts http://youtube.com/watch?v=IIlKiRPSNGA ;)) ok_cg is a very simple library that contains 6 function: setup_cgroups(cpu_exclusive, mem_exclusive, features, cgroup_mount_dir) create_groups_from_config(config, cgroup_mount_dir) create_cgroup(cgroup, cgroup_mount_dir) change_default_cgroup_opts(cgroup, opts, cgroup_mount_dir) add_tasks_to_cgroup(cgroup, args, pgrep_args, cgroup_mount_dir) get_pids(arg, pgrep_args) providing an interface for python functions in c, c++ etc is quite simple http://elmer.sourceforge.net/ The problem is that these functions requires a bit complicated data structures for example: [['games', '10', 'NULL', 'NULL', 'NULL', 'NULL', {'cpuset.memory_spread_page': '0', 'cpuset.memory_spread_slab': '0', 'cpuset.mems': '0', 'cpuset.mem_exclusive': '0', 'cpuset.cpu_exclusive': '0', 'notify_on_release': '0', 'cpuset.memory_pressure': '0', 'cpuset.memory_pressure_enabled': '0', 'cpuset.sched_load_balance': '1', 'cfq.ioprio': '0', 'cpuset.memory_migrate': '0', 'cpuset.cpus': '0', 'memory.limit_in_bytes': 'NULL'}, ['michal'], ['michal'], ['mc','firefox-bin']]] I'm not sure if it's possible to create a simple interface between C and Python in such case.
