Kuze kube muva nje, ukugcina izinga lokushisa leseva kwakuyindaba yobuchwepheshe kuphela engaqashelwa kakhulu, kodwa izinto zishintshe kakhulu. Ngokwamukelwa kabanzi kobuhlakani bokwenziwa obukhiqizayo, ukupholisa kube yinto enqumayo ekunqumeni ukuthi singakwazi ukusebenzisa amandla ekhompyutha angakanani nokuthi kuzobiza malini ukuwagcina esebenza.
Inkinga ukuthi ama-rack amanje afinyelela ubuningi bamandla obukhulu, adlula kalula ama-kW angu-50. Lokhu kukwenze kwacaca ukuthi umoya opholile wendabuko awusanele, okuphoqa imboni ukuthi ithathe isinyathelo esisheshayo sokupholisa uketshezi ngqo , okusuke ekubeni ukuhlolwa kwelebhu kwaba yizinga lanoma ubani ofuna ukuncintisana kulo mkhakha.
Umqondo ophazamisayo wokupholisa amanzi ashisayo
Kungase kuzwakale kuyinto exakile ukuzama ukupholisa iprosesa usebenzisa amanzi ashisayo, kodwa yilapho kanye umlingo ukhona. Sikhuluma ngezinhlelo lapho i-coolant ingena khona emazingeni okushisa angu- 40°C noma ngisho no-45°C , into eminyakeni embalwa edlule eyayingabonakala njengeresiphi yenhlekelele.
Le ndlela, ekhumbuza izinga lokushisa le-jacuzzi, isekelwe ezimisweni eziyisisekelo zefiziksi. Ama-AI chips akhiqiza ukushisa okuningi kangangokuthi uketshezi oluqukethe amanzi angu-75% kanye ne-25% propylene glycol lungamunca umthwalo wokushisa, noma amanzi eseshisa kakade. Uketshezi lungena ku-45°C bese luphuma kusekethe cishe ku-55°C, okuvumela iprosesa ukuthi isebenze ngaphandle kokuthi ukusebenza kwayo kuthinteke ukupholisa kwamanzi ashisayo kwezinhlelo zokusebenza ze-AI.
Inzuzo enkulu ukuthi, ngokusebenza emazingeni okushisa aphezulu, umehluko wokushisa nomoya wangaphandle mkhulu kakhulu. Lokhu kuvumela uhlelo ukuthi lusebenze ngokunganaki ezindaweni eziningi ezifudumele kusetshenziswa ama-radiator angaphandle, okususa isidingo sama-chiller kagesi asebenzisa amandla amaningi.
Izakhiwo ezithuthukisiwe: Ama-Cold plate nama-CDU ahlakaniphile
Ukushintsha nje uketshezi akwanele; lonke uhlelo ludinga ukwakhiwa kabusha. Isihluthulelo sisezindizeni ezibandayo ezinezakhiwo ezincane zangaphakathi. Indilinga yekhwalithi ephezulu ibamba phakathi kuka-80% no-90% wokushisa okukhiqizwayo, okuvumela isikhungo sedatha ukuthi sithembele ezindizeni ezomile ezisebenzisa amandla amancane.
Ngakolunye uhlangothi, sinama-CDU (ama-Coolant Distribution Units). Ukuze siwavimbele ekubeni yisithiyo sesistimu, i-Eaton iphakamisa ukuthi lawa mayunithi abe ahlakaniphile futhi ahlanganiswe nokwakhiwa kukagesi. Lapho izinhlelo zamandla nezokupholisa zikhuluma ulimi olufanayo, kufezwa ukuthembeka okukhulu kakhulu kusukela ku-chip kuya kugridi yamandla, kusungulwe indinganiso entsha yengqalasizinda ye-AI.
- Ukonga amandla: Izindleko zamandla zingancishiswa phakathi kuka-20% no-40%.
- Okuningi ngekhompyutha: Ngokukhulula isabelomali samandla kuma-cooler, ama-GPU amaningi angasebenza, kufezwe Ukwanda komkhiqizo ngo-33% kusuka efektri ye-AI.
- Ukusimama kwamanzi: Ngokusebenzisa amasekethe avaliwe agcwaliswa kanye kuphela, imibhoshongo yokuhwamuka iyasuswa, okunciphisa ukusetshenziswa kwamanzi cishe ngo-100%.
Icala lokwakhiwa kwe-NVIDIA's Rubin
I-NVIDIA inyuse lokhu yaya ezingeni elilandelayo ngokwakhiwa kwayo kwe-Rubin. Baqede abalandeli abanomsindo, abavame ukudlula ama-decibel angu-85, futhi bavala amabhodi e-server, bakha uhlelo lokupholisa uketshezi olusuka ekugcineni kuya ekugcineni . Empeleni, bafinyelele ushintsho oluphazamisayo lwe-NVIDIA lwe-AI ngokuvuselela indlela ukushisa okusatshalaliswa ngayo kuseva.
Kodwa-ke, akuzona zonke izindaba ezinhle. Nakuba i-NVIDIA isixazulule inkinga yamanzi ngaphakathi kwezikhungo zayo, umthelela wangaphandle kwezemvelo usalokhu uyinselele. Ukukhiqizwa kukagesi okudingekayo kulezi zikhungo kusathembele kakhulu kugesi wemvelo namalahle, okudla amanzi amaningi ngesikhathi senqubo yokukhiqizwa kukagesi.
Naphezu kwalezi zinselele zangaphandle, ushintsho alunakuguqulwa. Njengoba ubuningi bamandla bukhula, ukupholisa umoya kuya ngokungalingani, futhi ukupholisa koketshezi kuba yisisombululo esibalulekile, hhayi sokuzikhethela, sokuqinisekisa ukuthi ama-chip awaphumeleli ngaphambi kwesikhathi futhi agcine ukusebenza okuphezulu.
Indlela eya ku-AI esimeme ihilela ukuhlanganisa ukuphathwa kokushisa nokusatshalaliswa kukagesi, ukwenza ngcono i-watt ngayinye ukuze iyiguqule ibe amandla okusebenzisa ikhompyutha. Ukwamukela izinhlelo zamanzi ashisayo ezivaliwe akugcini nje ngokuthuthukisa inzuzo yebhizinisi ngokonga ugesi, kodwa futhi kubeka indinganiso yengqalasizinda yedijithali yeminyaka eyishumi ezayo.
