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?
