Ebifo Byonna ebya AI Computing Systems Bitwala Enkola z'okunyogoza ez'amazzi agaggaddwa-Loop?

Olw’okugaziwa okw’amangu okw’okutendekebwa okw’ekyokulabirako ky’olulimi olunene, okuteebereza kwa AI okuzaala n’ebibinja bya GPU eby’obungi-density, eminara egy’okunyogoza empewo egy’ennono n’eminara egy’okunyogoza egy’okufuumuuka egy’olubeerera tegikyasobola kutuukiriza byetaago bya nzirukanya ya bbugumu eby’ebifo eby’omulembe ebya kompyuta ebya AI.

 

Mu kiseera kino, ebifo ebinene-ebya AI supercomputing hubs, hyperscale cloud vendor AI bases neenterprise self-ezimba ebibinja bya GPUbonna batwalaclosed-loop liquid cooling nga standard supporting system, so nga small-scale lightweight AI computing rooms ziyinza okukyasigaza air cooling nga enteekateeka ey'enkyukakyuka. Closed-loop cooling efuuse core mandatory infrastructure for high-load AI computing scenarios, era omuze gwayo omujjuvu-popularization omuze tegukyuka mu mulimu.

 

 

 

 

Ensonga enkulu lwaki enkola za closed-loop zifugaAI cooling bulimbamu kulinnya okw’amaanyi okw’omugugu gw’ebbugumu lya chip. Chips za AI empya-omulembe nga NVIDIA Blackwell, AMD MI300X ne GPU ez’omutindo ogwa waggulu-ez’omunda zirina amaanyi g’ebbugumu aga chip emu-agasukka 700W, era kabineti emu eya mutindo esobola okutwala emigugu gy’ebbugumu egya 80–150kW, nga gisukka nnyo ekkomo erya waggulu erya 10–20kW ery’empewo{10}}cooled kabineti.

 

Okunyogoza empewo kwesigamye ku kukyusa empewo okutambuza ebbugumu, nga kulina obulungi bw’okutambuza ebbugumu obutono n’amaanyi ga ffaani amangi ennyo, ekisika PUE okutwalira awamu eya data center okutuuka ku 1.3–1.5.

 

Closed-loop liquid cooling ekozesa payipu ezisibiddwa okutambuza coolant butereevu ku cold plates eziyungiddwa ku chips, nga efficiency y’okutambuza ebbugumu esukka 85%, esala ku cooling power consumption ne 30%–40% era nga esika PUE wansi wa 1.1, era nga 45℃warm closed-loop scheme esembyeyo okuva ku NVIDIA esobola n’okukendeeza PUE okutuuka 1.08.

 

Enkizo eno ey'okukekkereza amaanyi-ekendeeza butereevu ku nsaasaanya y'emirimu gya bases ennene eza AI:kompyuta ya AI eya 50MW super-scalecenter esobola okukekkereza obukadde bwa ddoola za Amerika obusoba mu buna mu ssente z’amasannyalaze buli mwaka oluvannyuma lw’okukyusa okudda ku closed-loop cooling.

 

 

 

 

 

Puleesa y’ebintu by’amazzi ye nsonga endala enkulu evuddeko okwettanira mu bujjuvu enkola za closed-loop mu bifo bya AI. Eminaala egy’okunyogoza egy’olubeerera gyesigamye ku kufuumuuka kw’amazzi okusobola okusaasaanya ebbugumu, nga gikozesa obukadde bwa ggaloni z’amazzi amayonjo buli mwaka buli megawatt y’amaanyi ga kompyuta, ekivaako obukwakkulizo obukakali obw’amateeka mu bitundu ebitaliimu mazzi-.

 

Closed-loop cooling ekola enzirukanya bbiri ezeetongodde ezisibiddwa: circuit ey’omunda egatta server cold plates neeminaala egy’okunyogoza egyaggaddwaeyawuddwa ddala okuva mu mbeera ey’ebweru, nga amazzi aganyogoza gajjula omulundi gumu ne gaddamu okukozesebwa okumala obulamu bwonna, kumpi zero okufiirwa kw’okufuumuuka mu kiseera ky’okukola okwa bulijjo.

 

Emisango gy'amakolero omuli OpenAI Stargate AI training base ne Microsoft new-generation computing park byonna bikwata full closed-loop architecture, okusala ku nkozesa y'amazzi buli mwaka okutuuka ku ddaala ly'eky'okulya ekitono, mu musingi okugonjoola ensonga y'obulumi enkozesa y'amazzi eya "AI water hogs".

 

Eminaala egy’okunyogoza egyaggaddwa egyakwatagana n’enkola eno gyawula amazzi g’enkola ey’omunda n’amazzi ag’ebweru ag’okufuuyira nga gayita mu koyilo z’ekyuma ekitali kizimbulukuse, kale amazzi amayonjo agatambula tegakwatagana na nfuufu, ebiwuka n’obucaafu mu mpewo, okwewala okukutuka n’okukulukuta kw’ebipande ebinyogoza ebya seeva, n’okwongezaayo obulamu bw’obuweereza bwa seeva ezinyogoza ez’amazzi emyaka egisukka mu 5 bw’ogeraageranya n’enkola enzigule.

 

 

 

Closed-loop cooling era ereeta embeera z'emirimu ezitebenkedde ezikulu ennyo mu AI computing. Okutendekebwa okw’ekyokulabirako ekinene kyetaagisa okufuga ebbugumu okunywevu okumala essaawa 7×24h awatali kutaataaganyizibwa; okukyukakyuka kw’ebbugumu kujja kuleeta okukendeeza ku frequency ya GPU, ekivaako okutendekebwa okutaataaganyizibwa n’okufiirwa kwa kompyuta okw’amaanyi.

 

Loopu essiddwa mu bujjuvu ey’enkola za loopu eziggaddwa-erina ppampu ezikyusa frequency ez’amagezi, modulo ezitegeera ebbugumu n’okufuga okuyita mu ngeri ey’otoma, eziyinza okukuuma enkyukakyuka y’ebbugumu ly’okugabibwa kw’amazzi aganyogoza mu diguli ±0.5 omwaka gwonna.

 

Mu biseera by’omusana, eby’omuggalo n’ekiro eky’ebbugumu eri wansi, enkola eno ekyuka mu ngeri ey’otomanatural free cooling mode, okuggala chillers okwongera okukendeeza ku maanyi agakozesebwa; mu kyeya eky’ebbugumu eringi-, ekolagana ne firiigi ey’obuyambi okukuuma okusaasaana kw’ebbugumu okunywevu awatali kukosebwa nfuufu, .omusenyu n’obunnyogovu obungimu mbeera ey’ebweru.

 

Okwawukana ku ekyo, eminaala egy’okunyogoza egy’olubeerera gitera okuzibikira payipu z’obucaafu, nga kyetaagisa okukozesa eddagala buli kiseera n’okukyusa amazzi, era okutebenkera kw’ebbugumu kubi, ekitasobola kuwagira mirimu gya kutendeka AI egy’ekiseera ekiwanvu-obutasalako.

 

 

 

Naye, si bisenge bya kompyuta byonna ebikwatagana ne AI-ebiteeka mu bujjuvu enkola z'okunyogoza eziggaddwa-loopu. Small-scale edge AI computing nodes, ebyuma ebitonotono ebitali ku mutimbagano eby’okuteebereza n’ebisenge by'okugezesa ebitono-densitynga amaanyi ga rack wansi wa 20kW bakyakozesa air cooling oba simple open cooling towers okufuga okuteeka ssente mu kusooka.

 

Ensonga ng’ezo zirina omugugu gw’ebbugumu omutono, obudde obutono obw’okukola obutasalako n’obuwulize obutono ku nkozesa y’amazzi, kale enkola za loopu eziggaddwa-zijja kuleeta ssente ezisukkiridde ez’okuzimba n’okuddaabiriza.

 

Naye ku bifo bya kompyuta ebya AI eby’omutindo ogwa wakati n’ebinene-ebirina kabineti za GPU ezisukka mu 10, omutindo gw’amakolero g’eggwanga ogw’ebifo ebigezigezi gututte bulungi okunyogoza amazzi mu ngeri ey’okuggalawo-loop ng’enteekateeka y’ensibuko ennyogovu esinga okwettanirwa, era pulojekiti empya eza kompyuta ez’amaanyi zeetaagibwa okutegekaclosed-okunyogoza kwa loopueminaala nga ebyuma ebiwanirira ebya mutindo.

 

 

 

 

 

Okusinziira ku ndowooza y’okuddiŋŋana kw’amakolero, okunyogoza kwa closed-loop kufuuse omutindo gwa dizayini ogw’omugatte ogw’ebizimbe bya AI eby’ensi yonna. NVIDIA's DSX AI factory reference design, enzimba enkulu ey'abatunzi b'ebire, eraga 100% full closed-loop liquid cooling ku GPU computing platforms zonna, okusazaamu ezizimbibwa-mu cooling fans za servers ddala.

 

Ebya wakaeast-data-west-okubalirira intelligent computing hubs, new energy AI training bases ne pharmaceutical material computing platforms byonna bikwata closed cooling tower matching closed-loop liquid cooling, okutuukiriza ebigendererwa bibiri eby’okukekkereza amaanyi, okukekkereza amazzi n’okukozesa kompyuta ez’obungi-density.

 

Nga tugenda mu maaso n’okulongoosa amaanyi ga chip za AI, omusingi gw’okuteekebwa mu nkola okukakatakoenkola za loopu eziggaddwa-ejja kwongera okukka wansi, era enteekateeka z’okunyogoza empewo ez’ekiseera zijja kuggyibwawo mpolampola mu mbeera za kompyuta eza wakati n’ennene.

 

 

 

Mu bufunze, ebyuma bya AI ebitono biyinza okwettanira okunyogoza empewo okumala akaseera, naye ebifo byonna ebitongole ebya kompyuta ebya AI ebya wakati n’ebinene, ebibinja by’okutendekebwa okw’amaanyi (super training clusters) n’ebifo eby’okukozesa kompyuta ebigezi ennyo (hyperscale intelligent computing hubs) birina okukozesaclosed-loop amazzi okunyogozaenkola eziwanirirwa eminaala egy’okunyogoza egyaggaddwa.

 

 

Ekigonjoola kino kigonjoola ensonga ssatu enkulu ez’obulumi ez’omugugu gw’ebbugumu omungi, okukozesa amazzi okuyitiridde n’okufuga ebbugumu okutali kwa nkalakkalira okwa kompyuta za AI, era kifuuse ekkubo lyokka eriwangaala ery’okuddukanya ebbugumu eri enkulaakulana ennene-ey’amakolero g’obugezi obukozesebwa.
