Multilevel Queue Teem caij . A ntau - theem kev teem caij tos algorithm partitions npaj txhij kab mus rau hauv ob peb cais kab . Cov txheej txheem raug muab tso tseg mus tas li rau ib qho kab , feem ntau ua raws li qee yam khoom ntawm cov txheej txheem, xws li lub cim xeeb loj, txheej txheem tseem ceeb, lossis hom txheej txheem.

Ib yam li ntawd, ntau kab yog dab tsi?

Ntau - kab cia koj configure ntau tshaj ib lub tsheb kab rau txhua qhov kev txhawb nqa network interface, kom ntau tshaj ib qho SND CPU tuaj yeem tswj cov tsheb khiav ntawm ib qho kev sib txuas hauv ib lub sijhawm. Qhov no sib npaug ntawm kev thauj khoom zoo ntawm SND CPUs thiab CoreXL firewall piv txwv CPUs.

Kuj Paub, dab tsi yog multilevel tawm tswv yim queue teem sij hawm? Multilevel Feedback Queue Teem caij . Hauv ib multilevel kab - teem caij algorithm, cov txheej txheem raug muab mus tas li rau a kab ntawm kev nkag mus rau qhov system. Multilevel tawm tswv yim kab teem caij Txawm li cas los xij, tso cai rau tus txheej txheem txav ntawm kab . Lub tswv yim yog cais cov txheej txheem nrog cov yam ntxwv sib txawv CPU-burst.

Ib tug kuj yuav nug, dab tsi yog 3 hom kev teem caij sib txawv?

Peb hom ntawm tus teem sijhawm yog 1) Lub sij hawm ntev 2) Lub sij hawm luv 3 ) Lub sijhawm nruab nrab. Lub sij hawm ntev tus teem sijhawm tswj cov kev pab cuam thiab xaiv cov txheej txheem los ntawm cov kab thiab thauj lawv mus rau hauv lub cim xeeb rau kev tua. Lub sijhawm nruab nrab tus teem sijhawm tso cai rau koj los tswj cov txheej txheem sib pauv.

Dab tsi yog qhov txawv ntawm multilevel queue thiab multilevel tawm tswv yim queue?

2. Ib Multilevel kab (MLQ) cov txheej txheem raug xa mus tas li rau ib qho kab raws li lawv lub cim xeeb loj, txheej txheem tseem ceeb lossis hom txheej txheem. Hauv Multilevel Feedback queue (MLFQ) nws tso cai rau kev txav mus los nruab nrab tus kab , raws li cov yam ntxwv ntawm lawv CPU tawg.
