Isibhengezo seProsesa yeCerebras β Cerebras Wafer Scale Engine (WSE) okanye iCerebras wafer scale injini β njengenxalenye yenkomfa yonyaka ye-Hot Chips 31 Ukujonga le monster ye-silicon, into emangalisayo ayikho nokuba banokuyikhulula enyameni. Isibindi soyilo kunye nomsebenzi wabaphuhlisi ababeka emngciphekweni wokuphuhlisa ikristale kunye nommandla we-46 ye-square millimeters kunye namacala angama-225 cm iyamangalisa. Ngempazamo encinci, izinga lesiphako li-21,5%, kwaye iindleko zomcimbi kunzima ukucinga.
I-Cerebras WSE iveliswa yi-TSMC. Inkqubo yezobuchwepheshe: 16 nm FinFET. Lo mvelisi waseTaiwan naye ufanelwe yisikhumbuzo sokukhululwa kweCerebras. Ukuveliswa kwe-chip enjalo kufuna ubuchule obuphezulu kunye nokusombulula iingxaki ezininzi, kodwa kwakufanelekile, abaphuhlisi baqinisekisa. I-Cerebras chip yeyona nto iphezulu kwi-chip enokuphuma okumangalisayo, ukusetyenziswa kwamandla okuncinci kunye nokuhambelana okumangalisayo. Ngoku sisisombululo esifanelekileyo sokufunda koomatshini kwaye iya kuvumela abaphandi ukuba baqalise ukusombulula iingxaki ezinzima kakhulu.
I-Cerebras WSE nganye die iqulethe i-1,2 yetriliyoni ye-transistors, ehlelwe kwii-400 ze-AI-optimized compute cores kunye ne-000 GB ye-SRAM esasazwayo yendawo. Konke oku kudityaniswe yi-network ye-mesh kunye ne-throughput epheleleyo ye-petabits ezili-18 ngomzuzwana. I-Memory bandwidth ifikelela kwi-100 PB/s. Uluhlu lwenkumbulo lukwinqanaba elinye. Akukho memori ye-cache, akukho kudlula, kunye nokulibaziseka okuncinci kokufikelela. Luyilo olufanelekileyo lokukhawulezisa imisebenzi enxulumene ne-AI. Amanani ahamba ze: xa kuthelekiswa nezona core zegraphics zangoku, iCerebras chip ibonelela ngamaxesha angama-9 ngaphezulu kwememori ye-chip kunye namaxesha angama-3000 ngaphezulu kwesantya sokudlulisa imemori.
I-Cerebras computing cores - i-SLAC (i-Sparse Linear Algebra Cores) - zicwangciswe ngokupheleleyo kwaye zinokuphuculwa ukuze zisebenze kunye naluphi na uthungelwano lwe-neural. Ngaphaya koko, uyilo lwe-kernel luhluza ngokwendalo idatha emelwe ngu-zero. Oku kukhulula izixhobo zekhompuyutha kwisidingo sophinda-phindo olungasebenziyo ngo-zero imisebenzi, nto leyo kwimithwalo yedatha enqabileyo ithetha ukubala ngokukhawuleza kunye nokusebenza ngokugqithisileyo kwamandla. Ke, iprosesa yeCerebras ijika ibe ngamakhulu okanye namawaka amaxesha asebenzayo ngakumbi kumatshini wokufunda ngokwendawo ye-chip kunye nokusetyenziswa kunezisombululo zangoku ze-AI kunye nokufunda komatshini.
Ukuvelisa itshiphu yobukhulu obufanayo izisombululo ezininzi ezizodwa. Kwade kwafuneka ukuba ipakishwe kwityala phantse ngesandla. Kwakukho iingxaki ngokunikezela ngamandla kwikristale kunye nokuyipholisa. Ukususwa kobushushu kuye kwenzeka kuphela ngolwelo kwaye kuphela ngombutho wonikezelo lwezonal kunye nokujikeleza ngokuthe nkqo. Nangona kunjalo, zonke iingxaki zasonjululwa kwaye i-chip yaphuma isebenza. Kuya kuba mnandi ukufunda malunga nokusetyenziswa kwayo okusebenzayo.
