Eyasungulwa eminyakeni eyisishiyagalombili edlule, inkampani yaseBrithani iGraphcore isivele izenzele igama ngokukhululwa kwama-accelerator anamandla e-AI, atholwe ngemfudumalo ngabakwaMicrosoft noDell. Ngenkathi ama-accelerator e-Graphcore ehloselwe ikakhulukazi i-AI, akunakushiwo okufanayo kuma-GPU we-NVIDIA, alungiselwe imisebenzi ye-AI. Mayelana nenani lama-transistors asetshenzisiwe, i-Graphcore ifihla ngisho nenkosi esanda kumenyezelwa yama-chips e-AI, iphrosesa ye-NVIDIA A100.
Isixazululo se-NVIDIA sika-A100 esisekelwe ekwakhiweni kwe-Ampere siqukethe ama-transistors ayizigidi eziyizinkulungwane ezingama-54. Iphrosesa entsha ye-7-nm Graphcore Colossus MK2 (GC200 IPU) inama-transistors ayizigidi eziyizinkulungwane ezingama-59,4 ekufeni kwayo. Lokhu kuyenza i-chip eyinkimbinkimbi kakhulu emhlabeni (ingabe ibalwa izilo eziyisinkwa esilucwecwana esisodwa). ) wadlulela kumaNgisi.
I-chip ngayinye ye-GC200 iqukethe ama-processor cores azimele angu-1472 ahlelwe "ngamathayela" futhi angasebenzisa imicu yekhompuyutha ehambisanayo engu-8832. Isixazululo sangaphambilini sale nkampani besifaka ama-cores ayi-1216 nemicu eyi-7296. I-"tile" ngayinye ifakwe i-memory block yayo. Idizayini entsha inenani elingu-900 MB lememori ehlanganisiwe, kuyilapho iphrosesa yangaphambili yayino-300 MB kuphela.
Lesi sixazululo siletha umphumela omkhulu kakhulu kuma-accelerator e-Graphcore. Ikhompyutha yeshelufu eyodwa yerack evamile enezisheshisi ezine ze-Colossus MK2 iletha i-petaflop eyodwa yokusebenza. Ama-IPU angu-64 asebenza ndawonye aletha ama-exaflops angu-16 okusebenza. Iplathifomu ye-Graphcore ikala kalula ngokwengeza amayunithi anokucushwa okuzenzakalelayo, okunweba kakhulu ukufinyelela kwama-accelerator enkampani.
Ngaphambili iMicrosoft Sebenzisa inkundla ye-Graphcore kumasevisi wamafu e-Azure ukuze uthole ukunakwa kwemibuzo yolimi lwemvelo. Izixazululo ze-Graphcore kuthiwa ziletha izikhathi ezingu-100 ukusebenza kwamapulatifomu e-AI asekelwe ku-GPU. Hhayi-ke, okungenani i-Graphcore ibonakala iphumelela emkhakheni wayo. Imali yayo yemakethe isondela ku-$2 billion, futhi ubuchwepheshe benkampani abukasukumi ngempela.
