  1. You can use cpulimit link to limit CPU usage. Install cpulimit using below command.

    sudo apt install cpulimit

    Run stress command.

    stress -c 2 -i 1 -m 1

    Check stress PID using ps

    ps -ef | grep stress

dedunu   14822 14821 34 14:56 pts/15   00:06:29 stress -c 1 -i 1 -m 1
dedunu   14823 14821 37 14:56 pts/15   00:07:07 stress -c 1 -i 1 -m 1
dedunu   14824 14821 40 14:56 pts/15   00:07:39 stress -c 1 -i 1 -m 1

    You can see PIDs of the stress command. Run cpulimit command for each and every stress process. 

    sudo cpulimit -p 14821 -l 80
sudo cpulimit -p 14822 -l 80
sudo cpulimit -p 14823 -l 80
sudo cpulimit -p 14824 -l 80
