British Graphcore yatulutsa purosesa ya AI yomwe imaposa NVIDIA Ampere

Yakhazikitsidwa zaka zisanu ndi zitatu zapitazo, kampani ya ku Britain ya Graphcore yadzipangira kale dzina ndi kutulutsidwa kwa ma accelerator amphamvu a AI, olandiridwa mwachikondi ndi Microsoft ndi Dell. Ma accelerator opangidwa ndi Graphcore poyambilira amayang'ana AI, zomwe sitinganene za ma NVIDIA GPU osinthidwa kuti athetse mavuto a AI. A chitukuko chatsopano Graphcore idaphimba ngakhale mfumu yatsopano ya AI chips, purosesa ya NVIDIA A100, malinga ndi kuchuluka kwa ma transistors omwe akukhudzidwa.

Yankho la NVIDIA A100 kutengera kamangidwe ka Ampere lili ndi ma transistors 54 biliyoni. Purosesa yatsopano ya 7nm Graphcore Colossus MK2 (IPU GC200) ili ndi ma transistors 59,4 biliyoni pa chip yake. Chifukwa chake, korona wa chip chovuta kwambiri padziko lapansi (kupatula chilombo chimodzi chambale Zosangalatsa) adapita ku Britain.

Chip chilichonse cha GC200 chimanyamula ma processor odziyimira pawokha 1472 mu mawonekedwe a "matayilo" ndipo amatha kupanga ulusi wowerengera 8832 molumikizana. Yankho lakale la kampaniyo linali chowonjezera chokhala ndi ma cores 1216 ndi ulusi wa 7296. "Tile" iliyonse imakhala ndi kukumbukira kwake. Kukula kwatsopano kuli ndi 900 MB ya kukumbukira mkati, pamene purosesa yapitayi inali ndi 300 MB yokha ya kukumbukira.

Yankho lotere limapereka kuchuluka kwakukulu kwa ma Graphcore accelerators. Chifukwa chake, kompyuta ya alumali imodzi yachiyikapo chokhazikika yokhala ndi ma accelerator anayi a Colossus MK2 imakhala ndi ma petaflops amodzi. Kugwira ntchito limodzi 64 zikwi IPUs kudzapereka magwiridwe antchito a 16 exaflops. Kuchulukitsa kwa nsanja ya Graphcore kumachitika ndikungowonjezera midadada ndi kasinthidwe kokha, komwe kumakulitsa kwambiri gulu la ogwiritsa ntchito ma accelerator a kampaniyo.

Poyamba Microsoft kuyambira Gwiritsani ntchito nsanja ya Graphcore mu Azure Cloud Services kuti muzindikire mafunso m'zilankhulo zachilengedwe. Mayankho a Graphcore akuti ndiachangu nthawi 2 kuposa nsanja za AI zochokera ku GPU. Chabwino, Graphcore ikuwoneka kuti ikuyenda bwino m'munda wake. Chuma chake chamsika chili pafupi ndi $ XNUMX biliyoni, ndipo ukadaulo wa kampaniyo sunachokebe.
