Multithreading (los yog xov kev sib piv ) muab lub sijhawm zoo nkag mus rau cov neeg tsim khoom kom ua tiav cov software ua tau zoo dua thaum siv cov txheej txheem ntau yam. Nrog rau txoj hauv kev no, qhov kev zov me nyuam nws tus kheej spawns threads ntawm kev tua, uas tuaj yeem raug tua los ntawm ntau lub cores ntawm lub kaw lus kom khiav ntawm tus kheej.
Ib yam li ntawd, tib neeg nug, yog multithreading parallel processing?
Multithreading yog ib daim ntawv ntawm parallel xam nyob rau hauv hais tias nws yog tso cai rau tej yam xws li nco cov ntaub ntawv rau ua tib lub sij hawm raws li cov lus qhia tsis cuam tshuam, tab sis nws tsuas yog ib qho ntawm ntau hom parallelism siv - qhov tseem ceeb yog qhov sib txawv ntawm kev ua tiav pipelined.
Qhov thib ob, qhov sib npaug sib npaug sib txawv li cas ntawm threading? Muaj ib tug loj loj txawv muaj nyob nruab nrab ntawm ob lub tswv yim, tab sis ob qho tib si ua haujlwm ntau yam hauv txoj kev sib txuam. Parallel programming yog ua raws li cov txheej txheem siab dua ntawm Xov . Threads raug tua nyob rau hauv ib tug tub ntxhais ntau dua, yog li load muab rau cov tub ntxhais yog tsis phua raws li qhov sib npaug
Tib neeg kuj nug, puas yog multithreading txhim kho kev ua haujlwm?
Multi threading txhim kho kev ua tau zoo los ntawm kev tso cai rau ntau lub CPUs ua haujlwm ntawm qhov teeb meem tib lub sijhawm; Tab sis nws tsuas yog pab tau yog tias ob yam muaj tseeb: tsuav yog CPU ceev yog qhov txwv tsis pub tshaj (tsis yog lub cim xeeb, disk, lossis network bandwidth) THIAB ntev li ntev tau multithreading tsis qhia ntau yam haujlwm ntxiv (aka
Dab tsi yog thread nyob rau hauv parallel xam?
Nyob rau hauv ib tug multiprocessor los yog multi-core system, ntau yam xov tuaj yeem ua tiav hauv thaum uas tig mus , nrog txhua tus processor lossis cov tub ntxhais ua haujlwm sib cais xov ib txhij; ntawm lub processor lossis core nrog hardware xov , cais software xov kuj tuaj yeem ua tiav ib txhij los ntawm cov khoom siv sib cais xov.

Koj puas tuaj yeem muaj nyob rau hauv ib qho kev tshaj tawm? cov lus teb yog "tsawg kawg 12." txhawb ntxiv. ntawm saj, tab sis muaj qhov txwv. Muaj ob theem ntawm kev taw qhia (tus taw tes rau tus taw tes rau ib yam dab tsi) yog qhov ntau
Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
