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.
Ingabe i-Linux isebenzisa ukuhlela kwe-robin eyindilinga?
Izinqubo Zokuhlela Isikhathi Sangempela
I-Linux isebenzisa i-FCFS kanye Iround Robin isikhathi sangempela ukuhlela amakilasi. Umhleli uhlala eqhuba inqubo ngokubaluleke kakhulu. Phakathi kwezinqubo zokubaluleka okulinganayo, i-Linux iqhuba inqubo elinde isikhathi eside kakhulu.
Iyiphi i-algorithm yokuhlela esetshenziswa ku-Unix?
The I-algorithm ye-Round Robin ngokuvamile isetshenziswa ezindaweni zokwabelana ngesikhathi. I-algorithm esetshenziswa isihleli se-Linux iwuhlelo oluyinkimbinkimbi olunenhlanganisela yokubeka kuqala kuqala kanye nokusika isikhathi okuchemile. Inikeza i-quantum yesikhathi eside emisebenzini ebaluleke kakhulu kanye nenani lesikhathi esifushane ukwehlisa imisebenzi ebalulekile.
Ikuphi isihleli se-Linux?
Yonke ikhodi yesihleli isingenile i-kernel/sched/ directory.
Iyiphi i-algo yokuhlela ehamba phambili?
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.
Iyiphi i-algorithm yokuhlela esetshenziswa njengamanje ku-Windows OS ne-Linux?
Ukuhlela inqubo yeWindows
2) Izinguqulo ze-Windows ezisekelwe ku-NT zisebenzisa isihleli se-CPU esisekelwe kumugqa wempendulo wamazinga amaningi, okuchazwe amaleveli okubalulekile angu-32. Kuhloswe ukuthi kuhlangatshezwane nalezi zidingo zokuklama ezilandelayo zezinhlelo ze-multimode: Nikeza okuncamelayo emisebenzini emifushane. Nikeza okuncamelayo kuzinqubo ezibophezelekile ze-I/O.
Iyiphi i-algorithm yokuhlela esetshenziswa yi-OS?
Ukuhlela okubalulekile i-algorithm engalungiseleli futhi ingenye yama-algorithms wokuhlela ajwayeleke kakhulu kumasistimu enqwaba. Inqubo ngayinye inikezwe okubalulekile. Inqubo ebaluleke kakhulu kufanele yenziwe kuqala njalo njalo. Izinqubo ezinokubaluleka okufanayo zisetshenziswa ngokunikezwa kuqala.
Ngabe ukuhlela kusebenza kanjani ku-Linux?
I-Linux isebenzisa a I-algorithm ye-Completely Fair Schedule (CFS)., okuwukuqaliswa komugqa olungile we-weighted fair (WFQ). Cabanga ngesistimu ye-CPU eyodwa ongaqala ngayo: Isikhathi se-CFS sisika i-CPU phakathi kwemicu egijima. Kunesikhawu sesikhathi esimisiwe lapho uchungechunge ngalunye ohlelweni kufanele lusebenze okungenani kanye.
Ngisishintsha kanjani isihleli ku-Linux?
Ukushintsha isihleli sibe yi- "bfq" isihleli, ifake usebenzisa umyalo ongezansi. Manje sebenzisa umyalo "wekati" ofanayo. Manje i-“bfq” isifakiwe, inike amandla usebenzisa umyalo ofanayo “we-echo”. Hlola isihleli se-“bfq” esizenzakalelayo ngomyalo “wekati”.
Ingabe i-Linux isasebenzisa i-CFS?
I-Completely Fair Scheduler (CFS) iwumhleli wenqubo owahlanganiswa waba ngu-2.6. 23 (Okthoba 2007) ukukhishwa kwe-Linux kernel futhi iyisihleli esimisiwe semisebenzi yekilasi le-SCHED_NORMAL (okungukuthi, imisebenzi engenazo izithiyo zokusebenzisa zesikhathi sangempela).

Isihleli Esilungile Ngokuphelele.

Ngisetha kanjani i-Noop scheduler?
4 Izimpendulo. Hlela /etc/default/grub, njenge-gksudo gedit /etc/default/grub , lapha udinga ukwengeza i-elevator=noop. Shintsha GRUB_CMDLINE_LINUX_DEFAULT=”i-splash ethule” kuya ku-GRUB_CMDLINE_LINUX_DEFAULT=”ikheshi elithulekile le-splash=noop” . Bese ugijima i-sudo update-grub2 bese uqala kabusha.
Ngimisa kanjani isihleli se-Linux?
Sebenzisa i-opscmd. cmd (noma i-opscmd.sh ku-UNIX) umyalo wokumisa bese uqala Isihleli.
