Chizvarwa chinotevera cheNVIDIA GPUs, ingangodaidzwa kuti Ampere, ichapa zvakakosha kuita mabhenefiti pamusoro pemhinduro dzazvino, Iyo Inotevera Platform inoshuma. Chokwadi, isu tiri kutaura nezve graphics processors anoshandiswa mukombuta accelerators.
Makomputa accelerator pachizvarwa chitsva NVIDIA GPUs ichashandiswa muBig Red 200 supercomputer paIndiana University (USA), yakavakirwa papuratifomu yeCray Shasta. Ivo vanozowedzerwa kune sisitimu zhizha rino panguva yechipiri chikamu chekuvakwa kweiyo supercomputer.
Parizvino, hazvina kutaurwa kuti aya achava maGPU api, nekuti NVIDIA haisati yaaburitsa, asi zviri pachena kuti tiri kutaura nezve chizvarwa chitsva cheTesla accelerators yakavakirwa paAmpere. Zvinonyanya kuitika kuti NVIDIA ichazivisa chizvarwa chitsva cheGPUs yayo munaKurume pachiitiko chayo , uyezve maaccelerator matsva anobva paari anofanira kunge akagadzirira munguva yezhizha.
Zvinonzi iyo Big Red 200 system yakatanga kurongwa kuve neazvino Tesla V100 accelerators paNVIDIA Volta GPUs. Izvi zvaizobvumira iyo supercomputer kuti iwane peak performance ye5,9 Pflops. Zvisinei, gare gare zvakasarudzwa kumirira zvishoma, kugovera kuvakwa kweBig Red 200 mumatanho maviri, uye kushandisa zvitsva zvinokurumidza.
Muchikamu chekutanga chekuvaka, hurongwa hwe672 dual-processor clusters yakagadzirwa yakavakirwa pa64-core AMD Epyc 7742 chizvarwa cheRome processors. Chikamu chechipiri chinosanganisira kuwedzera kweEpyc Rome-based node itsva, iyo ichave yakashongedzerwa neimwe kana kupfuura inotevera-chizvarwa NVIDIA GPUs. Nekuda kweizvozvo, kuita kweBig Red 200 kuchasvika pa8 Pflops, uye panguva imwechete maGPU accelerator mashoma achashandiswa pane zvakarongwa.
Zvinoitika kuti kuita kwechizvarwa chitsva GPUs kuchave 70-75% yakakwirira kupfuura Volta. Ehe, izvi zvine chekuita ne "kushama" kuita mune imwechete chaiyo mashandiro (FP32). Naizvozvo, zvave kunetsa kutaura kuti zvirevo zvine chekuita nekuwedzera kwakadai kwekuita ndezvechizvarwa chitsva cheGeForce makadhi evhidhiyo evatengi. Ngativimbei kuti vatengi vepakati vachawanawo maGPU ane simba.
