Tshaj tawm ntawm Cerebras processor - Cerebras Wafer Scale Cav (WSE) lossis Cerebras wafer nplai cav - Raws li ib feem ntawm lub rooj sib tham txhua xyoo Kub Chips 31. Saib ntawm cov dab silicon no, qhov xav tsis thoob tsis yog qhov tseeb tias lawv tuaj yeem tso nws hauv cev nqaij daim tawv. Kev ua siab loj ntawm kev tsim thiab kev ua haujlwm ntawm cov neeg tsim khoom uas muaj kev pheej hmoo tsim cov siv lead ua nrog thaj tsam ntawm 46 square millimeters nrog rau sab ntawm 225 cm yog qhov xav tsis thoob.Nws yuav siv tag nrho 21,5-mm wafer los ua ib lub processor. Nrog rau qhov yuam kev me me, qhov tsis xws luag yog 300%, thiab tus nqi ntawm qhov teeb meem tseem nyuaj rau xav txog.
Cerebras WSE yog tsim los ntawm TSMC. Cov txheej txheem thev naus laus zis: 16 nm FinFET. Qhov chaw tsim khoom Taiwanese no kuj tsim nyog tau txais lub cim rau kev tso tawm Cerebras. Kev tsim cov nti no yuav tsum muaj kev txawj ntse tshaj plaws thiab daws teeb meem ntau, tab sis nws tsim nyog, cov neeg tsim khoom paub tseeb. Lub Cerebras nti yog qhov tseem ceeb ntawm lub khoos phis tawj ntawm lub nti nrog cov khoom siv tsis txaus ntseeg, kev siv hluav taws xob tsawg thiab kev sib luag zoo heev. Qhov no yog tam sim no qhov zoo tshaj plaws kev kawm tshuab kev daws teeb meem uas yuav tso cai rau cov kws tshawb fawb pib daws cov teeb meem ntawm qhov nyuaj heev.
Txhua Cerebras WSE tuag muaj 1,2 trillion transistors, muab tso rau hauv 400 AI-optimized xam cores thiab 000 GB ntawm lub zos faib SRAM. Tag nrho cov no yog kev cob cog rua los ntawm ib tug mesh network nrog ib tug tag nrho throughput ntawm 18 petabits ib ob. Nco bandwidth mus txog 100 PB / s. Lub cim xeeb hierarchy yog ib theem. Tsis muaj cache nco, tsis muaj kev sib tshooj, thiab kev nkag mus qeeb tsawg. Nws yog qhov zoo tshaj plaws architecture rau kev ua kom nrawm rau AI cov haujlwm. Cov naj npawb liab qab: piv rau cov cores niaj hnub tshaj plaws, Cerebras nti muab 9 npaug ntau dua ntawm lub cim xeeb ntawm lub cim xeeb thiab 3000 npaug ntau dua lub cim xeeb hloov ceev.
Cerebras xam cores - SLAC (Sparse Linear Algebra Cores) - yog cov programmable tag nrho thiab tuaj yeem ua kom zoo rau kev ua haujlwm nrog txhua lub network neural. Ntxiv mus, lub kernel architecture inherently lim cov ntaub ntawv sawv cev los ntawm xoom. Qhov no tso cai rau xam cov peev txheej los ntawm qhov xav tau los ua haujlwm tsis ua haujlwm los ntawm kev ua haujlwm xoom, uas rau cov ntaub ntawv tsis sib xws txhais tau tias kev suav nrawm dua thiab kev siv hluav taws xob tsis zoo. Yog li, cov txheej txheem Cerebras hloov mus ua ntau pua lossis ntau txhiab lub sijhawm ua haujlwm tau zoo dua rau kev kawm tshuab hauv cov ntsiab lus ntawm thaj chaw nti thiab kev noj ntau dua li cov kev daws teeb meem tam sim no rau AI thiab kev kawm tshuab.
Manufacturing ib nti ntawm qhov loj me ntau cov kev daws teeb meem tshwj xeeb. Nws txawm yuav tsum tau ntim rau hauv rooj plaub yuav luag los ntawm tes. Muaj teeb meem nrog kev muab lub zog rau cov siv lead ua thiab ua kom txias. Thaum tshav kub kub tshem tawm ua tau tsuas yog nrog kua thiab tsuas yog nrog lub koom haum ntawm zonal mov nrog ntsug ncig. Txawm li cas los xij, tag nrho cov teeb meem tau daws tau thiab lub nti tawm ua haujlwm. Nws yuav nthuav kom kawm txog nws txoj kev siv tswv yim.
