M'badwo wotsatira wa NVIDIA GPU, womwe mwina umatchedwa Ampere, upereka phindu lalikulu pamayankho apano, The Next Platform malipoti. Zowona, tikulankhula za ma purosesa azithunzi omwe amagwiritsidwa ntchito mu computing accelerators.
Ma computing accelerators pa NVIDIA GPUs ya mbadwo watsopano idzagwiritsidwa ntchito mu Big Red 200 supercomputer ku Indiana University (USA), yomangidwa pa nsanja ya Cray Shasta. Adzawonjezedwa ku dongosolo lino m'chilimwe panthawi yachiwiri yomanga makompyuta apamwamba.
Pakadali pano, sizinatchulidwe kuti ma GPU awa adzakhala ati, chifukwa NVIDIA sinawawonetse, koma zikuwoneka kuti tikulankhula za m'badwo watsopano wa Tesla accelerators kutengera Ampere. Ndizotheka kuti NVIDIA ilengeza za m'badwo watsopano wa ma GPU ake mu Marichi pamwambo wake womwe , ndiyeno ma accelerator atsopano ozikidwa pa iwo ayenera kukhala okonzeka m'nthawi yachilimwe.
Zikunenedwa kuti dongosolo la Big Red 200 poyambirira lidakonzedwa kuti likhale ndi ma accelerator amakono a Tesla V100 pa NVIDIA Volta GPUs. Izi zitha kulola makompyuta apamwamba kwambiri kuti akwaniritse magwiridwe antchito apamwamba a 5,9 Pflops. Komabe, pambuyo pake adaganiza zodikirira pang'ono, kugawa ntchito yomanga Big Red 200 m'magawo awiri, ndikugwiritsa ntchito ma accelerator atsopano.
M'gawo loyamba lomanga, dongosolo la magulu 672 amitundu iwiri adapangidwa kutengera mapurosesa a 64-core AMD Epyc 7742 m'badwo wa Rome. Gawo lachiwiri likukhudza kuwonjezeredwa kwa ma node atsopano a Epyc Rome, omwe adzakhala ndi m'badwo umodzi kapena zingapo za NVIDIA GPUs. Zotsatira zake, ntchito ya Big Red 200 idzafika pa 8 Pflops, ndipo nthawi yomweyo ma accelerator a GPU ochepa adzagwiritsidwa ntchito kuposa momwe anakonzera.
Zikuoneka kuti machitidwe a mbadwo watsopano wa GPUs adzakhala 70-75% apamwamba poyerekeza ndi Volta. Zachidziwikire, izi zikukhudzana ndi magwiridwe antchito "opanda kanthu" pamachitidwe amodzi olondola (FP32). Chifukwa chake, tsopano ndizovuta kunena kuti mawu ofunikira okhudzana ndi kuwonjezeka kwakukulu kwa magwiridwe antchito ali bwanji pamakadi avidiyo ogula a GeForce. Tikukhulupirira kuti ogula wamba apezanso ma GPU amphamvu kwambiri.
