Qhov Tseem Ceeb Qhov Sib Txawv - Parallel vs Distributed Computing
Lub khoos phis tawj ua haujlwm raws li cov lus qhia los ntawm tib neeg. Parallel xam thiab faib xam yog ob hom kev suav. Kab lus no tham txog qhov sib txawv ntawm Parallel thiab Distributed Computing. Parallel suav yog siv hauv kev ua haujlwm siab xws li kev txhim kho supercomputer. Distributed xam muab cov ntaub ntawv scalability thiab sib xws. Google thiab Facebook siv kev faib xam rau kev khaws cov ntaub ntawv. Qhov sib txawv tseem ceeb ntawm kev sib piv thiab kev faib xam yog tias kev sib txuas ua ke yog ua ntau yam dej num siv ntau lub processors ib txhij thaum nyob rau hauv kev faib xam, ntau lub khoos phis tawj sib cuam tshuam los ntawm kev sib txuas lus thiab kev sib koom tes txhawm rau ua tiav lub hom phiaj. Txhua lub koos pij tawj hauv qhov kev faib tawm muaj lawv tus kheej cov neeg siv thiab pab qhia cov peev txheej.
Parallel Computing yog dab tsi?
Lub khoos phis tawj yog lub tshuab uas tuaj yeem ua haujlwm raws li cov lus qhia los ntawm tib neeg. Computer architecture qhia txog yuav ua li cas ua cov lus qhia muab rau lub computer. Yav dhau los computer systems muaj ib tug processor. Qhov teeb meem uas yuav tsum tau daws tau muab faib ua cov lus qhia. Cov lus qhia no tau muab rau tus processor ib tom qab. Hauv txhua lub sijhawm, tsuas yog ib qho kev qhia nkaus xwb. Tom qab ntawd tus processor, ua tiav cov lus qhia thiab muab tso tawm. Qhov no tsis yog ib tug zoo mechanism. Kev nrawm tuaj yeem txhim kho los ntawm kev nce qhov zaus, tab sis nws kuj nce qhov kub thiab txias. Qhov ntawd ua rau muaj cua sov ntau dua. Yog li ntawd, nws tsis yog ib qho yooj yim mus nce qhov ceev ntawm lub processor. Raws li qhov tshwm sim ntawm qhov kev suav sib piv no tau qhia.
Parallel suav kuj hu ua Parallel processing. Nws yog ib daim ntawv ntawm kev suav uas tuaj yeem nqa ntau qhov kev suav ib txhij. Parallel xam siv ntau processors. Qhov teeb meem yuav tsum tau daws yog muab faib ua discrete seem. Txhua feem yog txuas ntxiv mus rau hauv cov lus qhia. Cov lus qhia no tau muab faib ua cov processors. Yog li ntawd, ntau processors tab tom ua cov lus qhia ib txhij. Parallel la computing yog qhov tseem ceeb los ua qhov kev suav ua nyuaj vim cov processors faib cov haujlwm ntawm lawv. Nws kuj txuag sijhawm.
Daim duab 01: Parallel Computing
Muaj qee qhov tsis zoo ntawm cov kab ke sib txuas. Cov lus qhia ua los ntawm ib tus processor yuav xav tau los ntawm lwm tus processor. Qhov no tuaj yeem ua rau latency. Ntau tus processors kuj tseem kim. Cov ntsiab lus no yuav tsum tau xav txog thaum tsim cov kab ke sib txuas. Zuag qhia tag nrho, kev suav sib txuas ua ke pab khiav ntau cov lus qhia tib lub sijhawm kom ua tiav cov haujlwm.
Dab tsi yog kev faib xam?
Hauv lub neej txhua hnub, tus neeg siv tau lub computer ua haujlwm nrog cov ntawv thov xws li Microsoft Word, Microsoft PowerPoint. Cov teeb meem nyuaj yuav tsis ua tiav los ntawm kev siv ib lub computer. Yog li ntawd, ib qho teeb meem tuaj yeem muab faib ua ntau yam haujlwm thiab faib rau ntau lub khoos phis tawj. Cov khoos phis tawj no tuaj yeem sib txuas lus nrog lwm lub khoos phis tawj hauv lub network. Lawv txhua tus ua haujlwm zoo ib yam li ib qho chaw. Cov txheej txheem ntawm kev faib ib qho haujlwm ntawm ntau lub khoos phis tawj yog hu ua kev faib xam. Txhua lub khoos phis tawj hauv qhov system faib yog hu ua node. Ib pawg nodes yog pawg.
Kev faib khoom suav tau siv ntau daim ntawv thov niaj hnub no. Qee qhov piv txwv yog Facebook thiab Google. Lawv muaj ntau lab thiab lab tus neeg siv. Txhua tus neeg siv sib txuas lus nrog lwm tus, sib qhia cov duab thiab lwm yam. Cov ntaub ntawv loj no yog khaws cia siv kev faib xam. Automated teller machines nyob rau hauv tsev txhab nyiaj, xov tooj tes hauj lwm, cellular networks, faib databases kuj siv faib xam.
Daim duab 02: Kev faib tawm
Kev faib khoom suav muab ntau yam zoo. Distributed systems yog ncua mus rau kev loj hlob. Nws muab scalability, thiab nws yog ib qho yooj yim los faib cov peev txheej. Qee qhov tsis zoo yog tuaj yeem muaj teeb meem hauv network, thiab nws nyuaj rau tsim cov software faib.
Dab tsi yog qhov txawv ntawm Parallel thiab Distributed Computing?
