Kunezinhlobo ezimbili zenqubo ye-Linux, isikhathi esivamile nesangempela. Izinqubo zesikhathi sangempela zibaluleke kakhulu kunazo zonke ezinye izinqubo. Uma kunenqubo yesikhathi sangempela elungele ukusebenza, izohlala isebenza kuqala. Izinqubo zesikhathi sangempela zingase zibe nezinhlobo ezimbili zenqubomgomo, i-round robin kanye neyokuqala ekuphumeni kokuqala.

- I-OS Kernel. …
- Amasevisi angemuva. …
- OS Shell. …
- Iseva yezithombe. …
- Imvelo yedeskithophu. …

Iyini i-ID yenqubo ku-Linux?
Kuhlelo lwe-Linux kanye ne-Unix, inqubo ngayinye inikezwa i-ID yenqubo, noma i-PID. Lena yindlela isistimu yokusebenza ehlonza ngayo futhi ilandelele izinqubo. … Izinqubo zabazali zine-PPID, ongayibona kuzihloko zekholomu ezinhlelweni eziningi zokuphatha inqubo, okuhlanganisa phezulu , i-htop kanye ne-ps .
Iyini i-Process hierarchy ku-Linux?
Emyalweni ojwayelekile we-ps kufanele sibheke ngesandla inombolo ye-PID ne-PPID ukuze sazi ukuhlobana phakathi kwezinqubo. Ngefomethi yesigaba, izinqubo zengane ziboniswa ngaphansi kwenqubo yomzali eyenza kube lula ngathi ukuthi siyibuke.
Zigcinwa kuphi izinqubo ku-Linux?
Ku-linux, "isichazi senqubo" siyi-struct task_struct [kanye nezinye]. Lokhu kugcinwa endaweni yekheli le-kernel [ngenhla PAGE_OFFSET ] futhi hhayi endaweni yomsebenzisi. Lokhu kuhambisana kakhulu nama-bit kernel angu-32 lapho i-PAGE_OFFSET isethelwe ku-0xc0000000. Futhi, i-kernel inemephu yesikhala sekheli eyodwa eyayo.
Iyini i-Max yomsebenzisi izinqubo ze-Linux?
ku /etc/sysctl. conf. 4194303 umkhawulo omkhulu we-x86_64 kanye no-32767 we-x86. Impendulo emfushane yombuzo wakho : Inombolo yenqubo engenzeka ohlelweni lwe-linux AYINAMKHAWULO.
Zingaki izinqubo ezihambisanayo engingaziqalisa?
1 Impendulo. Ungakwazi ukwenza imisebenzi eminingi ngokuhambisana oyifunayo, kodwa iphrosesa inama-cores angu-8 kuphela ukuze icubungule imicu engu-8 ngesikhathi esisodwa. Abanye bazohlala beklelile futhi balinde isikhathi sabo.
Zingaki izinqubo ezingasebenza ngesikhathi?
Isistimu yokusebenza yemisebenzi eminingi ingase ivele ishintshe phakathi kwezinqubo ukuze inikeze ukubonakala kwezinqubo eziningi ezisebenza ngesikhathi esisodwa (okungukuthi, ngokuhambisana), nakuba empeleni inqubo eyodwa kuphela engenziwa nganoma isiphi isikhathi ku-CPU eyodwa (ngaphandle kwalapho i-CPU inezinhlamvu eziningi. , bese kuba i-multithreading noma okunye okufanayo...
