Which command would you use?

You dynamically configure a system to concurrently run tasks A1 and A2 using these commands:
mkdir /cgroup/cpu
mount -t cgroup -o cpu cpu /cgroup/cpu
mkdir /cgroup/cpu/A1
mkdir /cgroup/cpu/A2
echo 5 > /cgroup/cpu/A1/cpu.shares
echo 5 > /cgroup/cpu/A2/cpu.shares
mkdir /cgroup/cpuacct
mount -t cgroup -o cpuacct cpuacct /cgroup/cpuacct
