Kuziviswa kweCerebras processor ― Cerebras Wafer Scale Injini (WSE) kana Cerebras wafer scale injini ― sechikamu chemusangano wegore negore weHot Chips 31. Kutarisa ichi chikara chesilicon, chii chinoshamisa hachisi kunyange chokwadi chokuti vaigona kuisunungura munyama. Ushingi hwekugadzira uye basa revagadziri vakaisa panjodzi yekugadzira kristaro ine nzvimbo inosvika 46 square millimeters ine mativi e225 cm zvinokatyamadza. Zvinotora yakazara 21,5-mm wafer kugadzira imwe processor. Nekukanganisa kudiki, chiyero chinokanganisa 300%, uye mutengo wenyaya wakatooma kufungidzira.
Cerebras WSE inogadzirwa neTSMC. Tekinoroji maitiro: 16 nm FinFET. Uyu mugadziri weTaiwanese anokodzerawo chiyeuchidzo chekuburitswa kweCerebras. Kugadzirwa kweiyo chip kwaida hunyanzvi hwepamusoro uye kugadzirisa matambudziko mazhinji, asi zvaive zvakakosha, vanogadzira vanovimbisa. Iyo Cerebras chip ndeyechokwadi supercomputer pane chip ine zvinoshamisa kuburikidza nekubuda, kushoma mashandisiro emagetsi uye kunoshamisa kufanana. Iyi ndiyo ikozvino yakanakira muchina kudzidza mhinduro iyo inobvumira vaongorori kuti vatange kugadzirisa matambudziko ekuomarara kwakanyanya.
Imwe neimwe Cerebras WSE inofa ine 1,2 tiririyoni transistors, yakarongwa kuita mazana mana ezviuru AI-yakagadziridzwa compute cores uye 400 GB yemuno yakagoverwa SRAM. Zvese izvi zvakabatanidzwa ne mesh network ine yakazara throughput ye000 petabits pasekondi. Memory bandwidth inosvika 18 PB/s. Urongwa hwendangariro ndehwemwero-mwero. Iko hakuna cache memory, hapana kupindirana, uye kushoma kuwana kunonoka. Iyo yakanaka dhizaini yekumhanyisa mabasa ane chekuita neAI. Nhamba dzakashama: zvichienzaniswa neazvino magiraidhi cores, iyo Cerebras chip inopa 100 times more on-chip memory uye 9 times more memory yekumhanyisa kumhanya.
Cerebras computing cores - SLAC (Sparse Linear Algebra Cores) - inorongeka zvizere uye inogona kugadzirwa kuti ishande nechero neural network. Uyezve, iyo kernel architecture inosefa data inomiririrwa ne zeros. Izvi zvinosunungura zviwanikwa zvekombuta kubva pakudiwa kwekuita kuwedzeredza zvisina basa ne zero mashandiro, izvo kune sparse data mitoro zvinoreva kukurumidza kuverenga uye yakanyanyisa simba rekushandisa. Nekudaro, iyo Cerebras processor inoshanduka kuita mazana kana kunyange zviuru zvenguva zvakanyanya kushanda zvakanaka pakudzidza kwemuchina maererano nenzvimbo yechip uye mashandisirwo kupfuura mhinduro dzazvino dzeAI uye kudzidza muchina.
Kugadzira chip yehukuru hwakafanana akawanda akasiyana mhinduro. Yaitofanirwa kurongedzerwa mucase kuda kubatwa nemaoko. Paive nematambudziko ekupa simba kune kristaro nekuitonhodza. Kubvisa kupisa kwakagoneka chete nemvura uye chete nesangano rekupa zonal ne vertical circulation. Zvisinei, matambudziko ose akagadziriswa uye chip yakabuda ichishanda. Zvichave zvinonakidza kudzidza nezvekushandisa kwayo kunoshanda.
