cpulimit / resource quota

음.. 프로세스 별로 처리인가?

유저별로 제한이라던가 하는 기능은 없나보네..

$ cpulimit Error: You must specify a target process CPUlimit version 2.1 Usage: cpulimit TARGET [OPTIONS...] [-- PROGRAM]    TARGET must be exactly one of these:       -p, --pid=N        pid of the process       -e, --exe=FILE     name of the executable program file                          The -e option only works when                          cpulimit is run with admin rights.       -P, --path=PATH    absolute path name of the                          executable program file    OPTIONS       -b  --background   run in background       -c  --cpu=N        override the detection of CPUs on the machine.       -l, --limit=N      percentage of cpu allowed from 1 up.                          Usually 1 - 400, but can be higher                          on multi-core CPUs (mandatory)       -q, --quiet        run in quiet mode (only print errors).       -k, --kill         kill processes going over their limit                          instead of just throttling them.       -r, --restore      Restore processes after they have                          been killed. Works with the -k flag.       -s, --signal=SIG   Send this signal to the watched process when cpulimit exits.                          Signal should be specificed as a number or                          SIGTERM, SIGCONT, SIGSTOP, etc. SIGCONT is the default.       -v, --verbose      show control statistics       -z, --lazy         exit if there is no suitable target process,                          or if it dies           --             This is the final CPUlimit option. All following                          options are for another program we will launch.       -h, --help         display this help and exit

ulimit을 통해 전체 시스템에 대해서 일괄적으로 cpu및 메모리 등의 용량 제한을 걸 수 있는 듯?
