Isizukulwana esilandelayo see-NVIDIA GPUs, ekusenokwenzeka ukuba zibizwe ngokuba yi-Ampere, siya kubonelela ngeenzuzo ezibalulekileyo zokusebenza ngaphezulu kwezisombululo zangoku, Ingxelo yePlatform elandelayo. Enyanisweni, sithetha malunga neeprosesa zegraphics ezisetyenziswa kwii-accelerators zekhompyutha.
I-accelerators ekhompyutheni kwisizukulwana esitsha se-NVIDIA GPUs iya kusetyenziswa kwi-Big Red 200 supercomputer kwiYunivesithi yase-Indiana (USA), eyakhiwe kwiqonga le-Cray Shasta. Ziya kongezwa kwinkqubo kweli hlobo ngexesha lesigaba sesibini sokwakhiwa kwe-supercomputer.
Okwangoku, akucaciswanga ukuba yeyiphi na i-GPU eziya kuba yiyo, kuba i-NVIDIA ayikazivezi, kodwa ngokucacileyo sithetha ngesizukulwana esitsha se-Tesla accelerators esekwe kwi-Ampere. Kunokwenzeka ukuba i-NVIDIA ibhengeze isizukulwana esitsha see-GPU zayo ngo-Matshi kumsitho wayo , kwaye ke ii-accelerators ezintsha ezisekelwe kuzo kufuneka zilungele kanye ngexesha lasehlotyeni.
Kuxelwe ukuba i-Big Red 200 inkqubo yayicetywe ekuqaleni ukuba ixhotyiswe nge-accelerator ye-Tesla V100 yangoku kwi-NVIDIA Volta GPUs. Oku kuya kuvumela i-supercomputer ukuba ifezekise ukusebenza okuphezulu kwe-5,9 Pflops. Nangona kunjalo, kamva kwagqitywa ukuba kulinde kancinci, ukwahlula ukwakhiwa kweBig Red 200 ibe ngamanqanaba amabini, kwaye kusetyenziswe i-accelerators entsha.
Ngexesha lesigaba sokuqala sokwakha, inkqubo ye-672 ye-dual-processor clusters yadalwa ngokusekelwe kwi-64-core AMD Epyc 7742 isizukulwana seprosesa zaseRoma. Isigaba sesibini sibandakanya ukongezwa kwee-nodes ezintsha ze-Epyc Rome, eziza kuxhotyiswa nge-NVIDIA GPUs yesizukulwana esinye okanye ngaphezulu. Ngenxa yoko, ukusebenza kweBig Red 200 kuya kufikelela kwi-8 Pflops, kwaye kwangaxeshanye zimbalwa ii-accelerator ze-GPU ziya kusetyenziswa kunokuba bekucwangcisiwe.
Kuyavela ukuba ukusebenza kwesizukulwana esitsha se-GPU kuya kuba yi-70-75% ephezulu xa kuthelekiswa neVolta. Ngokuqinisekileyo, oku kuchaphazela ukusebenza "okungenanto" kwimisebenzi echanekileyo enye (FP32). Ke ngoko, ngoku kunzima ukutsho ukuba zithini iingxelo ezifanelekileyo malunga nokunyuka okubalulekileyo kokusebenza kwisizukulwana esitsha samakhadi evidiyo eGeForce. Masithembe ukuba abathengi abaphakathi baya kufumana ii-GPU ezinamandla ngakumbi.
