Symmetric multiprocessing ( SMP ) yog ib qho kev siv computer uas muaj ob lossis ntau dua processors txuas rau asingle memory thiab operating system (OS). SMP sib txuas ntau cov txheej txheem los ua kom tiav cov txheej txheem nrog kev pab ntawm tus tswv OS, uas tswj hwm kev faib khoom, ua tiav thiab kev tswj hwm.

Ib yam li ntawd, nws tau nug, SMP thiab AMP yog dab tsi?

AMP sawv rau Asymmetric Multi-Processing; SMP txhais tau tias Symmetric Multi-Processing. Cov ntsiab lus no tsis yog pob tshab. Yog li, kuv yuav sim ua kom muaj kev ua haujlwm niaj hnub no.

Tom qab ntawd, lo lus nug yog, koj txhais li cas los ntawm multiprocessor system? Multiprocessor Kev khiav haujlwm Qhov system hais txog kev siv ob lossis ntau qhov chaw ua haujlwm hauv nruab nrab (CPU) hauv ib lub computer qhov system . Cov no ntau CPUs yog hauv kev sib txuas lus sib koom sib koom lub tsheb npav hauv computer, nco thiab lwm yam khoom siv peripheral. Cov no systems yog hu ua tightlycoupled tshuab.

Ib yam li ntawd, tib neeg nug, dab tsi yog txhais los ntawm multiprogramming?

Multiprogramming yog ib daim ntawv rudimentary ntawm parallel ua nyob rau hauv uas ob peb cov kev pab cuam yog khiav nyob rau tib lub sij hawm ntawm ib tug uniprocessor. Txij li thaum muaj tsuas yog ib tug processor, muaj peev xwm tsis muaj tseeb ib txhij ua tiav ntawm cov kev pab cuam sib txawv. Rau tus neeg siv nws zoo nkaus li tias txhua qhov kev zov me nyuam ua haujlwm tib lub sijhawm.

Dab tsi yog qhov txawv ntawm symmetrical thiab asymmetric multiprocessing?

Hauv Symmetric Multiprocessing , processors qhia tib lub cim xeeb. Qhov tseem ceeb Qhov sib txawv ntawm Symmetric thiab Asymmetric Multiprocessing yog in SymmetricMultiprocessing tag nrho cov processor hauv system runtasks hauv OS. Tab sis, hauv Asymmetric Multiprocessing tsuas yog tus tswv processor khiav haujlwm hauv OS.
