Isimemezelo se-Cerebras processor β Cerebras Wafer Scale Engine (WSE) noma injini yesikali seCerebras wafer β njengengxenye yengqungquthela yaminyaka yonke ye-Hot Chips 31 Uma ubheka lesi silo se-silicon, okumangazayo akukhona ukuthi bebengayikhulula enyameni. Isibindi sokuklama kanye nomsebenzi wabathuthukisi ababeka engozini yokuthuthukisa ikristalu enendawo engamamilimitha-skwele angu-46 enezinhlangothi ezingu-225 cm kuyamangaza Kuthatha yonke i-wafer engu-21,5-mm ukwenza iphrosesa eyodwa. Ngephutha elincane, izinga lesici liyi-300%, futhi izindleko zenkinga kunzima ukuzicabanga.
I-Cerebras WSE ikhiqizwa yi-TSMC. Inqubo yezobuchwepheshe - 16 nm FinFET. Lo mkhiqizi waseTaiwan naye ufanelwe yisikhumbuzo sokukhululwa kwe-Cerebras. Ukukhiqizwa kwe-chip enjalo kudinga ikhono eliphakeme kakhulu nokuxazulula izinkinga eziningi, kodwa bekufanelekile, abathuthukisi bayaqinisekisa. I-Cerebras chip empeleni iyi-supercomputer ku-chip enokuphuma okumangalisayo, ukusetshenziswa kwamandla okuncane nokufana okumangalisayo. Lesi manje isixazululo esifanelekile sokufunda ngomshini esizovumela abacwaningi ukuthi baqale ukuxazulula izinkinga eziyinkimbinkimbi kakhulu.
Ukufa kwe-Cerebras WSE ngakunye kuqukethe ama-transistors angu-1,2 trillion, ahlelwe amakhompiyutha angu-400 e-AI-optimized AI kanye no-000 GB we-SRAM esabalalisiwe yendawo. Konke lokhu kuxhunywe inethiwekhi enemeshi enenani eliphelele lama-petabits ayi-18 ngomzuzwana. Umkhawulokudonsa wememori ufinyelela ku-100 PB/s. Ukuhlelwa kwenkumbulo kuyizinga elilodwa. Ayikho inkumbulo yenqolobane, akukho ukugqagqana, kanye nokubambezeleka okuncane kokufinyelela. Isakhiwo esihle sokusheshisa imisebenzi ehlobene ne-AI. Izinombolo ezinqunu: uma kuqhathaniswa nama-graphic cores esimanje kakhulu, i-chip ye-Cerebras inikeza inkumbulo ye-chip ephindwe izikhathi ezingu-9 kanye nesivinini sokudlulisa inkumbulo esiphindwe izikhathi ezingu-3000.
I-Cerebras computing cores - SLAC (Sparse Linear Algebra Cores) - iyahleleka ngokugcwele futhi ingalungiselelwa ukusebenza nanoma yimaphi amanethiwekhi emizwa. Ngaphezu kwalokho, i-kernel architecture ihlunga ngokwemvelo idatha emelelwa ngoziro. Lokhu kukhulula izinsiza zekhompuyutha esidingweni sokwenza ukuphindaphinda okungenamsebenzi ngokungasebenzi, okuthi ekulayishweni kwedatha okuyingcosana kusho izibalo ezisheshayo kanye nokusebenza kahle kwamandla ngokwedlulele. Ngakho-ke, iphrosesa ye-Cerebras iba ngamakhulu noma izinkulungwane zezikhathi ezisebenza kahle kakhulu ekufundeni komshini ngokuya ngendawo ye-chip nokusetshenziswa kunezixazululo zamanje ze-AI nokufunda komshini.
Ukukhiqiza i-chip yosayizi ofanayo izixazululo eziningi eziyingqayizivele. Kwaze kwadingeka ukuthi ifakwe ebhokisini cishe ngesandla. Kube nezinkinga ngokunikeza amandla kukristalu nokuyipholisa. Ukususwa kokushisa kwenzeka kuphela ngoketshezi futhi kuphela ngokuhlelwa kokuhlinzekwa kwendawo ngokujikeleza okuqondile. Nokho, zonke izinkinga zaxazululwa futhi i-chip yaphuma isebenza. Kuyoba mnandi ukufunda mayelana nokusetshenziswa kwayo okungokoqobo.
