add a project fraud, and assign user to this project
# projadd -U user1 user.test
change user user1 default project:
add a line to the end of /etc/user_attr
=> user1::::project=user.test
# id -p user1
uid=109(user1) gid=201(users) projid=100(user.test)
==> project.cpu-cap
==> a value of 100 means 100% of one CPU
add a project attribute:
# projmod -aK "project.cpu-cap=(priv,800,deny)" user.test => 50%
(it's a 16 cpu system)
# prctl -n project.cpu-cap -i project user.test
project: 100: user.test
