AMD ndi Cray sabata ino kuti pofika 2021 adzakhazikitsa makina apamwamba kwambiri padziko lonse lapansi, otchedwa Frontier. Zikuyembekezeka kuti kasitomalayo anali US department of Energy, ngakhale wamkulu wa AMD Lisa Su mu ndemanga pazachuma adandandalika ntchito zamtendere zomwe kompyuta yayikuluyi iyenera kuthana nayo: kafukufuku wazachilengedwe, kutanthauzira ma genome, kulosera zanyengo komanso kufunafuna magwero atsopano amphamvu.
Oimira AMD adapereka ndemanga zosangalatsa kwambiri kwa ogwira ntchito pamalowo , zomwe zimamveka bwino kapena pang'ono kuti ndi zigawo ziti zomwe AMD idakonzekera dongosolo la Cray. Monga tanena kale, makamaka pulojekitiyi AMD idapanga mapurosesa apakati a EPYC, komanso Radeon Instinct computing accelerators kutengera ma GPU okhala ndi kukumbukira kwa HBM (m'badwo sunatchulidwe).
Chinsinsi cha mapurosesa apakati a supercomputer yatsopano
Wachiwiri kwa Purezidenti wa AMD Forrest Norrod sanafotokoze kuti ndi ma processor ati omwe adzakhale maziko a Frontier supercomputer, koma adafotokoza momveka bwino kuti ndi mapurosesa ati omwe sangagwiritsidwe ntchito mmenemo. Kuchokera m'mawu ake, zimadziwika kuti mapurosesa awa sagwiritsa ntchito zomanga za Zen 2 za mapurosesa aku Roma omwe akukonzekera kulengezedwa mu gawo lachitatu, kapena zomanga za m'badwo wotsatira zomwe zimachokera ku mapurosesa a Milan, omwe ayenera kutulutsidwa mu 2020. Ma processor a Frontier's EPYC adzasinthidwa mwamakonda. Zowona, Lisa Su sakanatha kukana chiyeso chofotokozera kuti mapurosesa a supercomputer iyi adzakhazikitsidwa ndi zomangamanga zomwe zidzalowe m'malo mwa Zen 2. Zingaganizidwe kuti adzalandira zomangamanga za Zen 3. Mapulosesa oterewa ayenera kupangidwa pogwiritsa ntchito yachiwiri. -ukadaulo wa 7nm, wokhala ndi zinthu zomwe zimatchedwa Ultra-hard ultraviolet (EUV) lithography.
M'nkhaniyi, mwa njira, zikuwonekeratu kuti ndani yemwe anali mtsogoleri wa AMD pamsonkhano waposachedwa wa malipoti, ponena za kutuluka kwa 2020 kwa kasitomala watsopano kumbali ya "mwambo" zigawo, zomwe ziribe kanthu kochita ndi gawo lamasewera a console. Titha kuganiziridwa kuti kasitomala uyu akhoza kukhala Cray, chifukwa ma processor amayenera kukhazikitsidwa kompyuta yayikulu isanayambike mu 2021.
Forrest Norrod adadzilola kuseka kuti ngati dzina la akatswiri apadera a EPYC a polojekiti ya Frontier liwululidwa, lidzakumbutsa aliyense za mzinda wina waku Italy. Kampaniyo imatchula ma processor a seva okhala ndi zomanga za banja la Zen polemekeza mizinda yosiyanasiyana yaku Italy: Naples, Rome kapena Milan.
Chigawo chazithunzi Frontier imabisanso kugwirizana kwake ndi zomangamanga
Pankhani ya Radeon Instinct computing accelerators, AMD iyeneranso kusinthana ndi zosowa za Cray. Tsamba la Next Platform likuti zigawo izi za Frontier sizidzagwiritsa ntchito zomangamanga za Vega kapena Navi, koma zidzamangidwa mwachizolowezi. Mapulogalamu apadera amalola ma GPU kuti azifulumira kukonza ntchito zomwe zimafanana ndi kasinthidwe ka seva ndi machitidwe anzeru opangira.
Chisamaliro chapadera chimaperekedwanso pakuchita bwino kwa kusamutsa kwa data pakati pa mapurosesa apakati ndi ma graphics mu makina apakompyuta apamwamba. AMD yasintha mawonekedwe ake othamanga kwambiri a Infinity Fabric. Padzakhala mapurosesa azithunzi anayi pa purosesa yapakati.
Oimira Oak Ridge Laboratory, yomwe idzagwiritse ntchito makompyuta apamwamba a Frontier, m'mawu olondola kwambiri adawonetsa bwino kwa anzawo ochokera patsamba la The Next Platform kuti mtengo wogulira ma accelerator okhala ndi kukumbukira kwa HBM mpaka pano wadya kuchuluka kwa bajeti. kupanga makina apamwamba kwambiri a makompyuta. Mpaka posachedwa, AMD idalimbikitsa ma GPU okhala ndi kukumbukira kwa HBM makamaka m'gawo lothamangitsa zithunzi, koma posachedwa yakhala ikuwalimbikitsa kuti azitha kuthamangitsa makompyuta. Mu kotala yoyamba, inali mphamvu zabwino zoperekera ma accelerator oterowo omwe adathandizira AMD kukweza phindu lake komanso mtengo wapakati wogulitsa wazinthu zake.
Mu gawo la makompyuta apamwamba kwambiri, ma accelerator a NVIDIA Tesla adakumana ndi kukana mpikisano, ndipo izi sizinakhudze kwambiri ndondomeko yamitengo ya kampaniyi. Tsopano popeza AMD ili ndi chithandizo champhamvu kuchokera kwa opanga makompyuta apamwamba, mitengo imatha kuyandikira pafupi ndi milingo yabwino, ngakhale kukumbukira kwa HBM kukupitilira kukhala okwera mtengo.
