Ingabe Zonke Izikhungo Zekhompyutha ze-AI Zithatha Amasistimu Okupholisa Avaliwe-I-Loop Liquid Cooling?

Ngokukhula okusheshayo kokuqeqeshwa kwemodeli yolimi olukhulu, inkomba ye-AI ekhiqizayo kanye{0}}neqoqo eliphezulu le-GPU eliminyana, ukupholisa komoya okujwayelekile kanye nemibhoshongo yokupholisa ehwamukayo evulekile ngeke isakwazi ukuhlangabezana nezidingo zokulawula okushisayo kwezikhungo zesimanje zekhompyutha ze-AI.

 

Njengamanje,{0}}amahabhu amakhulu e-AI esezingeni eliphezulu, izisekelo ze-AI zomthengisi wamafu we-hyperscale kanyeibhizinisi{0}}elizakhele amaqoqo e-GPUbonke bathatheivaliwe-i-loop liquid cooling njengesistimu esekelayo evamile, kuyilapho amagumbi ekhompuyutha e-AI amancane{1}}esikali esilula asengagcina ukupholisa komoya njengesikimu sesikhashana. I-loop cooling-evaliwe sekuphenduke ingqalasizinda eyisibopho eyinhloko{4}}ezimo zekhompuyutha ze-AI eziphezulu zokulayisha, futhi izitayela zakhona ezigcwele{5}zokwenza abantu zibe ningi azikwazi ukuhlehliswa embonini.

 

 

 

 

Isizathu esibalulekile sokuthi kungani amasistimu{0}}avaliwe abusayoAI ukupholisa amangaekukhuphukeni okubukhali komthwalo wokushisa kwe-chip. Ama-chip-esizukulwane esisha se-AI afana ne-NVIDIA Blackwell, AMD MI300X kanye nama-GPU asekhaya aphezulu-asebenza kahle{4}}amandla e-chip thermal eyodwa angaphezu kuka-700W, futhi ikhabhinethi eyodwa evamile ingathwala imithwalo eshisayo engu-80–150kW, edlula kude umkhawulo womoya ongu-10–20kW{0} wekhabethe eliphezulu.

 

Ukupholisa komoya kuncike ekuhanjisweni komoya ukuze kudluliselwe ukushisa, ngokusebenza kahle kokudlulisa ukushisa okuphansi kanye nokusetshenziswa kwamandla kwabalandeli okukhulu, okuphusha i-PUE iyonke yesikhungo sedatha ifike ku-1.3–1.5.

 

Ukupholisa uketshezi oluvaliwe-oluvaliwe lwe-loop kusebenzisa amapayipi avaliwe ukuzungeza okupholisayo ngokuqondile kumapuleti abandayo axhunywe kuma-chips, ngokusebenza kahle kokudlulisa ukushisa okungaphezu kuka-85%, okunqanda ukusetshenziswa kwamandla okupholisa ngo-30%–40% nokuphusha i-PUE ibe ngaphansi kuka-1.1, kanye nesikimu sakamuva se-loop esingu-45℃esivaliwe esivela ku-NVIDIA singehlisa ngisho no-1. PUE.

 

Le nzuzo-yokonga amandla inciphisa ngokuqondile izindleko zokusebenza zezisekelo ezinkulu ze-AI:i-50MW super{1}}scale AI computingisikhungo singonga ngaphezu kwezigidi ezingu-4 zamadola ase-US ezikweletini zikagesi zonyaka ngemva kokushintshela ekupholiseni{1}}iluphu evaliwe.

 

 

 

 

 

Ingcindezi yomthombo wamanzi ingenye indlela eyinhloko yokwamukelwa ngokugcwele- kwamasistimu alophu avaliwe ezikhungweni ze-AI. Imibhoshongo yokupholisa evulekile incike ekuhwamukeni kwamanzi ukuze kukhishwe ukushisa, kudla izigidi zamalitha amanzi ahlanzekile njalo ngonyaka ngemegawathi ngayinye yamandla ekhompyutha, okubangela imikhawulo eqinile yokulawula ezindaweni{2}}ezintula amanzi.

 

Ukupholisa-iluphu evaliwe kwenza imijikelezo emibili ezimele evaliwe: isekethe yangaphakathi exhuma amapuleti abandayo eseva kanyeimibhoshongo yokupholisa evaliweihlukaniswe ngokuphelele nemvelo yangaphandle, isipholile esigcwaliswa kanye bese sigaywa kabusha kuwo wonke umjikelezo wempilo, cishe ukulahlekelwa ukuhwamuka okungama-zero phakathi nokusebenza okuvamile.

 

Izimo zemboni ezihlanganisa isisekelo sokuqeqeshwa se-OpenAI Stargate AI kanye nepaki yekhompyutha entsha-yesizukulwane esisha se-Microsoft konke kusebenzisa i-loop Architecture evaliwe ngokuphelele, enciphisa ukusetshenziswa kwamanzi kwaminyaka yonke kuze kufike ezingeni lendawo yokudlela encane, okuxazulula ngokuyisisekelo indawo yobuhlungu yokusetshenziswa kwamanzi "ye-AI water hogs".

 

Imibhoshongo yokupholisa evaliwe ehambisana nesistimu ihlukanisa amanzi enqubo yangaphakathi namanzi afutha angaphandle ngamakhoyili ensimbi engagqwali, ukuze amanzi ahlanzekile ajikelezayo angalokothi axhumane nothuli, ulwelwe nokungcola okusemoyeni, ukugwema ukukalwa nokugqwala kwamapuleti abandayo eseva, nokwelula impilo yesevisi yamaseva okupholisa uketshezi ngeminyaka engaphezu kwemi-5 uma kuqhathaniswa nezinhlelo ezivulekile.

 

 

 

Ukupholisa-iluphu evaliwe kuphinda kulethe izimo zokusebenza ezizinzile ezibalulekile kukhompyutha ye-AI. Ukuqeqeshwa kwemodeli enkulu kudinga ukulawulwa kokushisa okuzinzile okungu-7 × 24h; ukushintshashintsha kwezinga lokushisa kuzobangela ukuncipha kwemvamisa ye-GPU, okuholela ekuphazamisekeni kokuqeqeshwa nokulahlekelwa okukhulu kwekhompyutha.

 

Iluphu evalwe ngokugcwele-yamasistimu eluphu ifakwe amaphampu ahlakaniphile okuguqula imvamisa, amamojula ezwa izinga lokushisa kanye nokulawula okuzenzakalelayo kwe-bypass, okungagcina ukushintshashintsha kwezinga lokushisa lokupholisa ngaphakathi kuka-±0.5℃unyaka wonke.

 

Entwasahlobo, ekwindla kanye-nobusuku obunezinga lokushisa eliphansi, isistimu ishintshela kubo ngokuzenzakalelayoimodi yokupholisa yamahhala yemvelo, ukuvala ama-chillers ukuze kuqhutshekwe nokunciphisa ukusetshenziswa kwamandla; ehlobo{0}lezinga lokushisa eliphezulu, lisebenzisana nesiqandisi esisizayo ukuze sigcine ukushiswa kokushisa okuzinzile ngaphandle kokuthintwa uthuli,isihlabathi kanye nomswakama ophezuluendaweni yangaphandle.

 

Ngokuphambene, izindawo zokupholisa ezivulekile zivame ukuvaleka ukungcola kwamapayipi, okudinga ukuthakwa kwamakhemikhali okujwayelekile nokushintshwa kwamanzi, futhi izinga lokushisa liphansi, elingakwazi ukusekela{0}}imisebenzi yokuqeqesha yesikhathi eside engaphazamiseki ye-AI.

 

 

 

Nokho, akuwona wonke amagumbi ekhompuyutha ahlobene ne-AI{0}asebenzisa ngokugcwele{1}}amasistimu okupholisa amaluphu avaliwe. Amanodi ekhompuyutha amancane-esikali se-AI, okokusebenza kwe-lightweight okungaxhunyiwe ku-inthanethi kanyeamagumbi okuhlola-okuminyana aphansienamandla okugezela angaphansi kuka-20kW asasebenzisa ukupholisa umoya noma imibhoshongo yokupholisa elula evulekile ukuze ulawule ukutshalwa kwezimali kokuqala.

 

Izimo ezinjalo zinomthwalo ophansi wokushisa, isikhathi esifushane esiqhubekayo sokusebenza kanye nokuzwela okuphansi ekusebenziseni amanzi, ngakho amasistimu avaliwe{0}}aluphu azoletha izindleko ezeqile zokwakha nezokulungisa.

 

Kodwa ezikhungweni zekhompuyutha ze-AI ezimaphakathi nezinkulu-ezinamakhabethe e-GPU angaphezu kuka-10, amazinga emboni kazwelonke yezikhungo zekhompiyutha ezihlakaniphile athathelwe ngokusobala ukupholisa uketshezi oluvaliwe-njengohlelo oluncanyelwayo lomthombo obandayo, futhi amaphrojekthi amasha e-supercomputing ayadingeka ukuze amiswe.ukupholisa iluphu evaliwe-imibhoshongo njengemishini ejwayelekile yokusekela.

 

 

 

 

 

Ngokombono wokuphindaphinda kwezimboni,{0}}i-loop cooling evaliwe isibe izinga elihlanganisiwe ledizayini yengqalasizinda ye-AI yomhlaba wonke. Idizayini yereferensi yefekthri ye-DSX AI ye-NVIDIA, ukwakheka okujwayelekile kwabathengisi bamafu, icacisa ukupholisa okungu-100% okugcwele okuvalekile{3}}kuzo zonke izinkundla zekhompyutha ze-GPU, ukukhansela okwakhelwe{4}}ekupholiseni abalandeli bamaseva ngokuphelele.

 

Okwasekhayaimpumalanga-idatha-yasentshonalanga-ikhompyutha ii-ntelligent computing hubs, isisekelo sokuqeqeshwa kwe-AI entsha yamandla kanye nezinkundla zekhompuyutha zemithi konke kusebenzisa ukupholisa okuvaliwe kombhoshongo wokupholisa okuvaliwe{0}}okupholisa uketshezi lwe-loop, okufeza imigomo embaxambili yokonga amandla, ukonga amanzi kanye{1}}nekhompuyutha enamandla kakhulu.

 

Ngokuthuthukiswa okuqhubekayo kwamandla e-AI chip, umkhawulo wokuthunyelwa okuyimpoqoamasistimu-avaliwezizophinde zehliswe, futhi izinhlelo zokupholisa umoya ezishintshayo zizoqedwa kancane kancane ezimweni zekhompyutha ezimaphakathi nezinkulu.

 

 

 

Kafushane, imishini ye-AI enqenqemeni encane ingase isebenzise ukupholisa komoya okwesikhashana, kodwa zonke izikhungo zekhompuyutha ze-AI ezisemthethweni eziphakathi nendawo ezinkulu, amaqoqo okuqeqeshwa okuphezulu kanye namahabhu ekhompiyutha ahlakaniphile kufanele asetshenziswe.ivaliwe-i-loop liquid coolingamasistimu asekelwa imibhoshongo yokupholisa evaliwe.

 

 

Lesi sixazululo sixazulula izinhlungu ezintathu ezibalulekile zomthwalo wokushisa okuphezulu, ukusetshenziswa kwamanzi ngokweqile nokulawulwa kwezinga lokushisa okungazinzile kwekhompuyutha ye-AI, futhi sekuwukuphela kwendlela yokulawula ukushisa okuzinzile-embonini enkulu yobuhlakani bokwenziwa.
