Isizukulwane esilandelayo sama-NVIDIA GPUs, okungenzeka abizwe ngokuthi i-Ampere, sizonikeza izinzuzo ezibalulekile zokusebenza phezu kwezixazululo zamanje, I-Next Platform ibika. Yiqiniso, sikhuluma ngama-graphics processors asetshenziswa kuma-accelerator ekhompyutha.
Ama-accelerator ekhompyutha esizukulwane esisha se-NVIDIA GPU azosetshenziswa ku-Big Red 200 supercomputer e-Indiana University (USA), eyakhelwe kuplathifomu ye-Cray Shasta. Bazokwengezwa ohlelweni kuleli hlobo ngesikhathi sesigaba sesibili sokwakhiwa kwe-supercomputer.
Okwamanje, akucaciswanga ukuthi lawa azoba yimaphi ama-GPU, ngoba i-NVIDIA ayikawavezi, kodwa ngokusobala sikhuluma ngesizukulwane esisha sama-accelerator we-Tesla asekelwe ku-Ampere. Kungenzeka kakhulu ukuthi i-NVIDIA izomemezela isizukulwane esisha sama-GPU ayo ngoMashi emcimbini wayo , bese ama-accelerator amasha asekelwe kuwo kufanele alungele ngesikhathi sasehlobo.
Kubikwa ukuthi uhlelo lweBig Red 200 ekuqaleni lwaluhlelelwe ukuthi lufakwe ama-accelerator amanje e-Tesla V100 kuma-NVIDIA Volta GPU. Lokhu kuzovumela i-supercomputer ukuthi ifinyelele ukusebenza okuphezulu kwe-5,9 Pflops. Nokho, ngokuhamba kwesikhathi kwanqunywa ukuthi kume kancane, kuhlukanise ukwakhiwa kweBig Red 200 ibe izigaba ezimbili, futhi kusetshenziswe ama-accelerator amasha.
Phakathi nesigaba sokuqala sokwakha, kwasungulwa uhlelo lwamaqoqo angama-672-dual-processor asekelwe kumaphrosesa angu-64-core AMD Epyc 7742 esizukulwane sase-Rome. Isigaba sesibili sibandakanya ukwengezwa kwamanodi amasha asekelwe ku-Epyc Rome, azofakelwe isizukulwane esisodwa noma ngaphezulu se-NVIDIA GPUs. Ngenxa yalokho, ukusebenza kweBig Red 200 kuzofinyelela ku-8 Pflops, futhi ngesikhathi esifanayo kuzosetshenziswa ama-accelerator e-GPU ambalwa kunalokho obekuhleliwe.
Kuvele ukuthi ukusebenza kwesizukulwane esisha sama-GPU kuzoba phezulu ngo-70-75% uma kuqhathaniswa neVolta. Yebo, lokhu kuthinta ukusebenza "okungenalutho" ekusebenzeni okuqondile okukodwa (FP32). Ngakho-ke, manje sekunzima ukusho ukuthi izitatimende ezifanele mayelana nokwanda okuphawulekayo kokusebenza zingamakhadi wevidiyo yesizukulwane esisha seGeForce. Asethembe ukuthi abathengi abamaphakathi nabo bazothola ama-GPU anamandla kakhulu.
