I-CPULimit, ikhawulela ukusetshenziswa okwenziwa yinqubo nge-CPU

Esihlokweni esilandelayo sizobheka i-CPULimit. Leli ithuluzi lomugqa womyalo lelo kukhawulela ukusetshenziswa kwe-CPU ngenqubo (evezwe ngamaphesenti, hhayi isikhathi se-CPU). Lokhu kuzoba wusizo ekulawuleni imisebenzi yeqoqo, lapho singafuni inqubo yokusebenzisa imijikelezo eminingi kakhulu ye-CPU.

Ngokusetshenziswa kwaleli thuluzi ngeke sishintshe inani noma ezinye izilungiselelo ezibalulekile, kepha ukusetshenziswa kwangempela kwe-CPU. Ngaphezu kwalokho, iyakwazi ukuzivumelanisa nomthwalo ojwayelekile wohlelo, ngamandla futhi ngokushesha. Ukulawulwa kwenani le-CPU elisetshenzisiwe kwenziwa ngokuthumela izimpawu OKULANDELAYO y ISIGCONT I-POSIX kuzinqubo. Zonke izinqubo zezingane nemicu yenqubo ebekiwe zizokwabelana ngamaphesenti afanayo we-CPU.

Faka i-CPULimit

CPULimit kuyinto itholakala ezinqolobaneni eziningi ezizenzakalelayo zokusabalalisa okufana ne-Unix. Singayifaka sisebenzisa abaphathi bephakheji abazenzakalelayo ekusatshalalisweni kwe-Gnu / Linux. Ngesibonelo esiseduze, sizobona ukuthi singasifaka kanjani ku-Debian, Ubuntu naku-Linux Mint. Kuzofanele sivule kuphela i-terminal (Ctrl + Alt + T) bese sibhala umyalo olandelayo kuyo:

sudo apt-get install cpulimit

Noma ngubani ofuna ukubonisana nezinye izinhlobo zezindawo ezise- ikhasi le-GitHub leprojekthi.

Isebenzisa i-CPULimit

Lapho ithuluzi selifakiwe, sekuyisikhathi sokubona ukuthi isebenza kanjani. Ukwenza lokhu, sizoqalisa uhlelo olusebenzisa izinsiza eziningi ze-CPU. Imiyalo elandelayo kufanele isebenze njengomsebenzisi wezimpande.

Ukwakha iskripthi esisebenzisa izinsiza ze-CPU

Okokuqala siya dala ifayela elibizwa nge-derrochecpu.sh. Ngizosebenzisa i- Umhleli we-Vim, kodwa ukuthi ngamunye asebenzise eyodwa ayithandayo. Kusuka esigungwini (Ctrl + Alt + T) kuzofanele sibhale:

vim derrochecpu.sh

Uma sekuvuliwe, sizocindezela inkinobho ethi 'keyEsc' bese 'i'. Manje sizokwengeza imigqa elandelayo:

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

Ngalokhu kwenziwe, sekuyisikhathi sokugcina nokuphuma. Ukwenza lokhu sizocindezela ukhiye 'Esc'futhi sizobhala : wq ukugcina nokuvala ifayili. Lo mbhalo omfushane uzophinda usebenzise ngokukhulu ukushesha ukusetshenziswa kwe-CPU. Ngakho-ke, kunconywa ukuthi uyihlole kumshini obonakalayo.

Manje sizokwenza leli fayela lisetshenziswe. Ukuze wenze lokhu, kusuka esigungwini esifanayo (Ctrl + Alt + T) sizokwenza:

chmod +x derrochecpu.sh

Iqalisa iskripthi

Manje sizokwethula inqubo ngemuva. Sizokwenza lokhu sisebenzisa umyalo:

./derrochecpu.sh &

Sizogcina i-PID yenqubo. Kulokhu, i-6472 yi-PID yenqubo ethuliwe.

Ukuhlola ukuthi kudla malini i-CPU

Siyabona inani le-CPU le nqubo esisanda kuyisebenzisa isebenzisa i- umyalo «phezulu» esigungwini esifanayo:

top

Njengoba kungabonakala kusithombe-skrini esingenhla, inqubo ye-wastecpu.sh isebenzisa ngaphezu kwe-96% yokusetshenziswa kwe-CPU. Njengoba kudla ukusetshenziswa okuningi kwe-CPU, kunzima ukwenza eminye imisebenzi. Ngemuva kwemizuzu embalwa, isistimu ingaphahlazeka noma iqandiswe. Yilapho i-CPULimt isisiza khona.

Ikhawulela ukusetshenziswa kwe-CPU yi-PID

Manje, ake sikhawulele ukusetshenziswa kwe-CPU kwale nqubo sisebenzisa ithuluzi le-CPULimit. Siya nciphisa ukusetshenziswa kwe-CPU kuye kuma-35% nge-PID yayo ehambisanayo (cishe). Ukuze wenze kanjalo, sebenzisa:

cpulimit -l 35 -p 6472 &

• Inketho "-l 35»Ikhawulela inqubo ibe cishe kuma-35%.
• «-p 6472»Ingabe i-PID ye-derrochecpu.sh esiyibonile ngaphambili.

Ukuhlola umphumela we-CPULimit

Lapho umyalo wangaphambilini usuqalisiwe, ake sihlole ukusetshenziswa kwe-CPU kwenqubo futhi. Kulokhu sizophinda sisebenzise umyalo ophezulu futhi:

top

Njengoba ukwazi ukubona esithombeni ngenhla, ukusetshenziswa kwe-CPU kwe-darfulcpu.sh kwehlele ku-35,6%, okusondele kakhulu kuma-35%. Manje ya singaba nezinsizakusebenza eziningi ze-CPU ukwenza ezinye izinqubo.

Ikhawulela ukusetshenziswa kwe-CPU ngegama lefayela

Sibonile ukuthi singakhawulela kanjani inqubo usebenzisa i-PID. Kanjalo singawenza umyalo we-CPULimit ocacisa igama lefayela lohlelo olusebenzayo.

Isibonelo, isibonelo esifanayo ngenhla kungaba:

cpulimit -l 30 ./derrochecpu.sh &

I-CPULimit ingaba wusizo ngenkathi kuqhutshwa inqubo esebenzisa ukusetshenziswa kakhulu kwe-CPU. Ngokuzayo lapho siqaphela ukuthi uhlelo ludla i-CPU eningi kakhulu, kuzofanele ukuthi sithole i-PID yenqubo sisebenzisa umyalo «top«. Uma usunayo, kufanele ukhawulele ukusetshenziswa kwe-CPU yakho kube inani eliphansi usebenzisa umyalo we-CPULimit njengoba kuchaziwe kule ndatshana.

Khipha i-CPULimit

Ukususa leli thuluzi kusistimu yethu kulula njengokuvula i-terminal (Ctrl + Alt + T) nokuthayipha kuyo:

sudo apt remove cpulimit

Lokho okuchazwe yilo mbhalo yisibonelo nje. Ngokusobala, akekho noyedwa engqondweni yabo efanele ozovula iskripthi esifana nalesi esichazwe lapha kwikhompyutha yabo.
