cgroups functionality that was released in Linux Kernel version 2.6.24
Packages:
cgroup-lite:cgroups-mount, cgroups-umountcgroup-tools:cgcreate,cgexec,lscgroupamong otherscgroupfs-mount
systemd-cgls systemd-cgls memory systemd-cgtop
cgcreate -g memory:myGroup
cgexec -g memory:myGroup YOUR_PROGRAM_TO_EXEC
- You can use cgget to view the current limits, usage, & high watermarks of the cgroup
