I-Linux isebenzisa i-algorithm ye-Completely Fair Scheduling (CFS), ewukuqaliswa komugqa olungile onesisindo (WFQ). Cabanga ngesistimu ye-CPU eyodwa ongaqala ngayo: Isikhathi se-CFS sisika i-CPU phakathi kwemicu esebenzayo. Kunesikhawu sesikhathi esimisiwe lapho uchungechunge ngalunye ohlelweni kufanele lusebenze okungenani kanye.
Ukuhlela inqubo kwenziwa kanjani ku-Linux?
Ukuhlela kwe-Linux kusekelwe ku indlela yokwabelana ngesikhathi eseyethuliwe eSigabeni 6.3: izinqubo ezimbalwa zisebenza “ekuphindaphindeni kwesikhathi” ngoba isikhathi se-CPU sihlukaniswe “ngezingcezu,” esisodwa ngenqubo ngayinye eqhutshwayo. Yebo, iphrosesa eyodwa ingasebenzisa inqubo eyodwa kuphela nganoma isiphi isikhathi.

What is scheduling in Linux OS?
The scheduler is responsible for keeping the CPUs in the system busy. The Linux scheduler implements a number of scheduling policies, which determine when and for how long a thread runs on a particular CPU core. Scheduling policies are divided into two major categories: Realtime policies.
Ingabe ukuhlela kwenqubo nokuhlela kwe-CPU kuyafana?
Job scheduling and CPU Scheduling are associated with process execution. The job scheduling is the mechanism to select which process has to be brought into the ready queue. The CPU scheduling is the mechanism to select which process has to be executed next and allocates the CPU to that process.
Kuyini Ukuhlela Inqubo kanye nezinhlobo zayo?
Ukuhlela Inqubo iphatha ukukhethwa kwenqubo yomprosesa ngesisekelo se-algorithm yokuhlela kanye nokususwa kwenqubo kuphrosesa. Kuyingxenye ebalulekile yesistimu yokusebenza yezinhlelo eziningi. Kukhona imigqa eminingi yokuhlela esetshenziswa ekuhleleni inqubo.
Iyini imigqa yokuhlela?
Izinqubo ezihlala kumemori eyinhloko futhi ezilungele futhi ezilindele ukuqaliswa zigcinwa ohlwini wabiza ulayini olungile. … Lo mugqa ngokuvamile ugcinwa njengohlu oluxhunyiwe. Isihloko esilungele ulayini siqukethe izinkomba ze-PCB yokuqala neyokugcina ohlwini.
Ingabe isihleli siyinqubo?
Ukuhlela inqubo kuyi- ingxenye ebalulekile yezinhlelo zokusebenza ze-Multiprogramming. Amasistimu okusebenza anjalo avumela inqubo engaphezu kweyodwa ukuthi ilayishwe kumemori esebenzisekayo ngesikhathi futhi inqubo elayishiwe yabelana nge-CPU isebenzisa isikhathi sokuphindaphinda. Kunezinhlobo ezintathu zesihleli senqubo.
Iyiphi i-algorithm yokuhlela engcono kakhulu?
Ayikho i-algorithm yendawo yonke yokuhlela "engcono kakhulu"., futhi amasistimu okusebenza amaningi asebenzisa inwebe noma inhlanganisela yama-algorithms okushejula ngenhla. Isibonelo, i-Windows NT/XP/Vista isebenzisa ulayini wempendulo wamazinga amaningi, inhlanganisela yokuhlela okubalulekile okugxilile, i-round-robin, kanye ne-algorithms yokuqala, ukuphuma kuqala.
Ngazi kanjani uma umsebenzi we-cron usebenza ku-Linux?
Lapho umsebenzi usuqedile, ifayela /path/cron. ukuphela kuzoba nesitembu sesikhathi lapho i-cron iqeda. Ngakho a elula ls -lrt /path/cron. {qala, gcina} izokutshela ukuthi umsebenzi uqale nini nokuthi usasebenza (i-oda lizokutshela ukuthi lisasebenza).
Uyini umyalo we-PS EF ku-Linux?
Lo myalo uthi esetshenziselwa ukuthola i-PID (I-ID Yenqubo, inombolo ehlukile yenqubo) yenqubo. Inqubo ngayinye izoba nenombolo eyingqayizivele ebizwa ngokuthi i-PID yenqubo.
Ngisithola kanjani isihleli sami ku-Linux?
Uhlu lwemisebenzi ye-Cron ku-Linux
Ungawathola ngaphakathi /var/spool/cron/crontabs. Amathebula aqukethe imisebenzi ye-cron yabo bonke abasebenzisi, ngaphandle komsebenzisi wempande. Umsebenzisi wempande angasebenzisa i-crontab yesistimu yonke. Kuzinhlelo ezisekelwe ku-RedHat, leli fayela litholakala ku-/etc/cron.
