Isku xirka NVLink iyo GPU
NVLink iyo isku xidhka laxidhiidha waa isku xidhka xawliga sare leh ee u ogolaanaya GPU-yo badan inay si toos ah oo degdeg ah ula hadlaan midba midka kale.

They are essential because training and serving the largest AI models requires hundreds or thousands of GPUs to act like one giant accelerator.
quusid qoto dheer
Hal GPU ma hayn karo moodooyinka ugu waaweyn, sidaas darteed waxay u kala qaybsan yihiin jajabyo badan oo ay tahay in si joogto ah xogta la isku dhaafsado, sida miisaanka, gradients, iyo firfircoonida. Baska caadiga ah ee PCIe aad ayuu u gaabiyaa tan, marka NVIDIA waxay abuurtay NVLink, isku xirka GPU-to-GPU oo toos ah oo bixiya xajmi dheer oo fog iyo daahitaan hoose. Chips-yada NVSwitch waxay tan u fidiyaan maro sidaa darteed GPU kasta oo ku jira server wuxuu ku gaari karaa midba midka kale xawaare buuxa, isagoo siddeed GPUs u rogaya hal xusuusta weyn iyo barkadda xisaabinta. Marka la eego cabbirka rack, nidaamyada sida NVIDIA's NVL72 waxay ku xidhaan daraasiin GPU-yo ah oo ku saabsan domain NVLink midaysan. Marka laga soo tago hal rack, tignoolajiyada isku xidhka sida InfiniBand iyo Ethernet (badanaa leh RDMA) waxay xidhaan kumanaan qanjidhyo ah koox. Tayada isku xidhkaani waxay si toos ah u xadidaysaa inta ay le'eg tahay iyo sida ugu dhakhsaha badan ee moodooyinka loo tababari karo.
Aragtida Farsamada
NVLink waxay bixisaa haad-dhibic-dhibcood oo u dhexeeya GPU-yada leh bandwidth marar badan oo ah PCIe iyo daahitaan hoose, taasoo u oggolaanaysa GPU-yada inay midba midka kale akhriyaan xusuusta midba midka kale ku dhawaad sida inay tahay maxalli. NVSwitch wuxuu u dhaqmaa sida isgoysyada xawaaraha sare leh si dhammaan GPU-yada ku jira noodhka ay ula xiriiraan xannibaad la'aanta baaxadda ballaaran. Hawlgallada wadajirka ah sida dhammaan-dhimista, kuwaas oo isu geynaya jaangooyooyinka guud ahaan GPU-yada inta lagu jiro tababarka, ayaa si aad ah uga dheereeya dharkan, taas oo ah sababta isku-xirnaanta isku-xirnaanta ay si xooggan u saameynayso sida ugu wanaagsan ee tababbarku u cabbiro jajabyo badan.

Mustaqbalka NVLink iyo GPU Interconnects
Sida moodellada ka soo baxaan hal server, isku-xirku wuxuu noqonayaa nidaamka. NVLink waxa ay sii wadataa korodhka xajmiyeedka jiil kasta, iyo cabirka NVLink domains (sida NVL72) ayaa balaadhinaya tirada GPU-yada u dhaqma sidii hal. Filo qaybo waaweyn oo midaysan, isku xidhka adag ee xisaabinta iyo isku xidhka, isku xidhka indhaha si loo dhimo awooda fogaanta, iyo dadaalka warshadaha ee ku wajahan heerarka isku xidhka furan (sida UALink) ilaa dharka iska leh ee iska soo horjeeda. Cabbiraadda AI waxay si sii kordheysa ugu xiran tahay dhaqdhaqaaqa xogta u dhexeysa chips-yada ilaa inta ku jirta chips-yada laftooda.
