CPULimit, umda ekusebenzeni okwenziwa yinkqubo ye-CPU

Kwinqaku elilandelayo siza kujonga kwi-CPULimit. Esi sisixhobo somgca wokuyalela Imida yokusetyenziswa kwe-CPU ngenkqubo (ichazwe ngepesenti, hayi ixesha le-CPU). Oku kuyakuba luncedo kulawulo lwemisebenzi yebatch, xa singafuni inkqubo yokusebenzisa imijikelezo ye-CPU emininzi.

Ngokusetyenziswa kwesi sixhobo asizukutshintsha ixabiso okanye ezinye iisetingi eziphambili, kodwa eyona yona CPU. Ukongeza, iyakwazi ukuziqhelanisa nomthwalo wenkqubo ngokubanzi, ngamandla kwaye ngokukhawuleza. Ukulawulwa kwemali ye-CPU esetyenzisiweyo kwenziwa ngokuthumela iimpawu YIMISELE y UMQATHA POSIX kwiinkqubo. Zonke iinkqubo zomntwana kunye nemisonto yenkqubo echaziweyo iya kwabelana ngepesenti enye ye-CPU.

Faka i-CPULimit

CPULimit ngu ifumaneka kuninzi lwezinto zokugcina ezingafaniyo ze-Unix. Singayifaka sisebenzisa abaphathi beephakheji emiselweyo kulwabiwo lweGnu / Linux. Umzekelo okhoyo, siza kubona indlela yokuyifaka kwi-Debian, Ubuntu kunye ne-Linux Mint. Kuya kufuneka sivule kuphela i-terminal (Ctrl + Alt + T) kwaye sibhale lo myalelo ulandelayo:

sudo apt-get install cpulimit

Nabani na ofuna ukubonisana nezinye iindidi zoncedo kwi Iprojekthi yeprojekthi yeGitHub.

Sebenzisa i-CPULimit

Nje ukuba isixhobo sifakwe, lixesha lokuba sisebenze. Ukwenza oku, siza kuqhuba inkqubo esebenzisa izixhobo ezininzi ze-CPU. Le miyalelo ilandelayo kufuneka iqhutywe njengomsebenzisi wengcambu.

Ukwenza iskripthi esisebenzisa izixhobo zeCPU

Kuqala siya yenza ifayile ebizwa ngokuba derrochecpu.sh. Ndiza kusebenzisa i Umhleli weVim, kodwa nganye nganye isebenzisa enye ayithandayo. Ukusuka kwisiphelo sendlela (Ctrl + Alt + T) kuya kufuneka sibhale:

vim derrochecpu.sh

Xa sele uvulekile, siya kucofa iqhosha 'Esc' ke ngoku 'i'. Ngoku siza kongeza le migca ilandelayo:

#!/bin/bash
while :; do :; done;

Ngokwenza oku, lixesha lokugcina nokuphuma. Ukwenza oku siza kucofa iqhosha 'EscKwaye siya kubhala : wq ukugcina nokuvala ifayile. Iskripthi esifutshane siza kuphinda sisebenzise ngaphandle komthungo ukusetyenziswa kwe-CPU. Ke kuyacetyiswa ukuyivavanya kumatshini obonakalayo.

Ngoku siza kuyenza le fayile isebenze. Ukwenza oku, kwisiphelo esinye (Ctrl + Alt + T) siza kwenza:

chmod +x derrochecpu.sh

Ukuqalisa iskripthi

Ngoku siza kuphehlelela inkqubo ngasemva. Siza kwenza oku sisebenzisa lo myalelo:

./derrochecpu.sh &

Siza kugcina i-PID yenkqubo. Kule meko, i-6472 yi-PID yenkqubo esungulwe.

Ukujonga ukuba ingakanani i-CPU oyisebenzisayo

Siyalibona inani le-CPU le nkqubo sisandula ukuyisebenzisa, sisebenzisa umyalelo «phezulu» Kwisiphelo esinye:

top

Njengoko kunokubonwa kwisikrini esingentla, inkqubo ye-wastecpu.sh isebenzisa ngaphezulu kwe-96% yokusetyenziswa kwe-CPU. Kuba itya ukusetyenziswa kakhulu kweCPU, kunzima ukwenza eminye imisebenzi. Emva kwemizuzu embalwa, Inkqubo inokungqubeka okanye iqhwa. Kulapho i-CPULimt isinceda khona.

Ukunciphisa umda wokusetyenziswa kweCPU yiPID

Ngoku, masinciphise ukusetyenziswa kwe-CPU kwale nkqubo sisebenzisa isixhobo se-CPULimit. Siya ku Nciphisa ukusetyenziswa kwe-CPU ukuya kuma-35% ngokusebenzisa iPID yayo ehambelanayo (malunga). Ukwenza njalo, sebenzisa:

cpulimit -l 35 -p 6472 &

• Inketho "-l 35»Inciphisa inkqubo kumalunga nama-35%.
• «-iphe 6472»Ngaba i-PID yederrochecpu.sh esele siyibonile.

Ukujonga isiphumo seCPULimit

Wakuba usunguliwe umthetho wangaphambili, masiqwalasele ukusetyenziswa kwe-CPU yenkqubo kwakhona. Kule nto siza kuphinda sisebenzise owona myalelo uphezulu:

top

Njengoko ubona kumfanekiso ongentla, ukusetyenziswa kwe-CPU ye-wastefulcpu.sh yehle yaya kwi-35,6%, esondele kakhulu kwi-35%. Ngoku sinokuba nezixhobo ezininzi ze-CPU zokuqhuba ezinye iinkqubo.

Ukunciphisa umda wokusetyenziswa kweCPU ngegama lefayile

Siye sabona indlela yokunciphisa inkqubo usebenzisa i-PID. Njengokuba Singawenza umthetho we-CPULimit okhankanya igama lefayile yenkqubo enokufezekiswa.

Umzekelo, lo mzekelo ungasentla uya kuba:

cpulimit -l 30 ./derrochecpu.sh &

CPULimit kunokuba luncedo ngelixa kuqhutywa inkqubo echitha kakhulu ukusetyenziswa kwe-CPU. Ngexesha elizayo xa siqaphela ukuba inkqubo isebenzisa i-CPU eninzi, kuya kufuneka sifumane i-PID yenkqubo usebenzisa lo myalelo «umphezulu«. Xa unayo, kuya kufuneka unqande ukusetyenziswa kweCPU kwixabiso elisezantsi usebenzisa i-CPULimit command njengoko kuchaziwe kweli nqaku.

Khipha i-CPULimit

Ukususa esi sixhobo kwinkqubo yethu kulula njengokuvula i-terminal (Ctrl + Alt + T) kunye nokuchwetheza kuyo:

sudo apt remove cpulimit

Oko kuchazwe leli nqaku ngumzekelo nje. Ngokucacileyo, akukho namnye engqondweni yakhe olungileyo oya kusungula iskripthi esifana nale sichazwe apha kwikhompyuter yakhe.
