Sistimi ea DGX A100, e thehiloeng ho eona Jen-Hsun Huang haufinyane , e kenyelletsa li-GPU tse robeli tsa A100, li-switch tse tšeletseng tsa NVLink 3.0, balaoli ba marang-rang ba Mellanox ba robong, li-processor tse peli tsa AMD EPYC Roma tse nang le li-cores tse 64, 1 TB ea RAM le 15 TB ea SSD e tšehetsoeng ke NVMe.
NVIDIA DGX A100 ke moloko oa boraro oa sistimi ea komporo ea k'hamphani, e etselitsoeng haholo ho rarolla mathata a bohlale ba maiketsetso. Hona joale litsamaiso tse joalo li hahiloe holim'a li-processor tsa morao-rao tsa A100 tse tsoang lelapeng la Ampere, tse bakang keketseho e matla ea ts'ebetso ea bona, e fihlileng ho 5 petaflops. Ka lebaka la sena, DGX A100 e khona ho sebetsana le mefuta e mengata ea AI e rarahaneng le palo e kholoanyane ea data.
Bakeng sa sistimi ea DGX A100, NVIDIA e bonts'a feela kakaretso ea memori ea HBM2, e fihlang ho 320 GB. Lipalo tse bonolo tsa lipalo li re lumella ho fumana hore na GPU e 'ngoe le e' ngoe e na le 40 GB ea mohopolo, 'me litšoantšo tsa sehlahisoa se secha li hlakisa hore molumo ona o abuoa har'a mekotla e tšeletseng. Grafiken memory bandwidth e boetse e boleloa - 12,4 TB / s bakeng sa sistimi eohle ea DGX A100 ka kakaretso.
Ha re nahana hore sistimi ea DGX-1, e ipapisitseng le li-Tesla V100s tse robeli, e hlahisitse petaflops e le 'ngoe ka lipalo-palo tse tsoakiloeng, mme ho boleloa hore DGX A100 e sebetsa ho li-petaflops tse hlano, re ka nka hore lipalong tse ikhethileng Ampere GPU e le 'ngoe e lebelo ho feta makhetlo a mahlano. pele ho eona ka meralo ea Volta. Maemong a mang, molemo o fetoha habeli.
Ka kakaretso, sistimi ea DGX A8 e fana ka ts'ebetso e phahameng ea ts'ebetso ea 100 motsotsoana ts'ebetsong e felletseng (INT1016), ts'ebetsong ea "half-precision floating point" (FP16) - 5 petaflops, ts'ebetsong ea lintlha tse phaphametseng tse habeli (FP64) - 156 teraflops. . Ho feta moo, DGX A32 e fihlella ts'ebetso e phahameng ea 100 petaflops ho komporo ea tensor ea TF2,5. Ha re hopoleng hore teraflops e le 'ngoe ke ts'ebetso ea lintlha tse 1012 ka motsotsoana, petaflops e le' ngoe ke ts'ebetso ea lintlha tse 1015 ka motsotsoana.
Karolo ea bohlokoa ea li-accelerator tsa NVIDIA A100 ke bokhoni ba ho arola lisebelisoa tsa GPU e le 'ngoe ka likarolo tse supileng tsa sebele. Sena se o lumella ho eketsa haholo ho feto-fetoha ha maemo karolong e le 'ngoe ea maru. Mohlala, sistimi e le 'ngoe ea DGX A100 e nang le li-GPU tse robeli tsa 'mele e ka sebetsa joalo ka li-GPU tse 56. Theknoloji ea Multi-Instance GPU (MIG) e u lumella ho khetha likarolo tsa boholo bo fapaneng har'a li-cores tsa khomphutha hape e le karolo ea memori ea cache le memori ea HBM2, 'me li ke ke tsa qothisana lehlokoa le tse ling bakeng sa bandwidth.
Ke habohlokoa ho hlokomela hore ha ho bapisoa le mekhoa e fetileng ea DGX, anatomy ea DGX A100 e bile le liphetoho tse itseng. Palo ea liphaephe tsa mocheso ho li-radiator tsa li-module tsa SXM3, tseo ho tsona li-processor tsa A100 tse nang le mohopolo oa HBM2 li kentsoeng, li eketsehile haholo ha li bapisoa le li-module tsa Tesla V100 tsa moloko oa Volta, le hoja lipheletso tsa tsona li patiloe ponong ea motho ea tloaelehileng. ka likoahelo tse ka holimo. Moeli o sebetsang oa moralo ona ke 400 W ea matla a mocheso. Sena se boetse se tiisitsoe ke litšobotsi tsa molao tsa A100 phetolelong ea SXM3, e hatisitsoeng kajeno.
Haufi le li-GPU tsa A100 tse leboteng la bo-mme ho na le li-switches tse tšeletseng tsa moloko oa boraro oa NVLink, tseo hammoho li fanang ka phapanyetsano ea data ea litsela tse peli ka lebelo la 4,8 TB/s. NVIDIA e boetse e hlokometse ka botebo ho pholiso ea bona, ho ahlola ka li-radiator tse felletseng tse nang le liphaephe tsa mocheso. GPU e 'ngoe le e' ngoe e abetsoe likanale tse 12 tsa sebopeho sa NVLink; li-GPU tsa boahelani li ka fapanyetsana data ka lebelo la 600 GB/s.
Sistimi ea DGX A100 e boetse e na le balaoli ba marang-rang ba Mellanox ConnectX-6 HDR ba robong, ba khonang ho fetisa tlhahisoleseling ka lebelo le fihlang ho 200 Gbit/s. Ka kakaretso, DGX A100 e fana ka phetiso ea lintlha tse peli ka lebelo la 3,6 TB / s. Sistimi e boetse e sebelisa mahlale a Mellanox a nang le sepheo sa ho holisa lits'ebetso tsa komporo ka meaho e joalo. Ts'ehetso ea PCI Express 4.0 sethaleng e khethoa ke li-processor tsa AMD EPYC Roma; ka lebaka leo, sebopeho sena ha se sebelisoe feela ke li-accelerator tsa litšoantšo tsa A100, empa hape le li-drive tse tiileng tse nang le protocol ea NVMe.
Ho phaella ho DGX A100, NVIDIA e se e qalile ho fana ka balekane ba eona ka liboto tsa HGX A100, e leng e 'ngoe ea likarolo tsa lisebelisoa tsa seva tseo bahlahisi ba bang ba tla li hlahisa ka bobona. Boto e le 'ngoe ea HGX A100 e ka amohela li-GPU tse 'ne kapa tse robeli tsa NVIDIA A100. Ntle le moo, bakeng sa litlhoko tsa eona, NVIDIA e se e bokelletse DGX SuperPOD - sehlopha sa litsamaiso tse 140 tsa DGX A100, tse fanang ka ts'ebetso ho li-petaflops tse 700 tse nang le litekanyo tse itekanetseng ka kakaretso. Khamphani e tšepisitse ho fana ka thuso ea mekhoa ho balekane ba lakatsang ho theha lihlopha tse tšoanang tsa komporo ho latela DGX A100. Ka tsela, ho ile ha nka NVIDIA nako e fetang khoeli ho haha DGX SuperPOD sebakeng sa likhoeli tse 'maloa kapa lilemo tse tloaelehileng bakeng sa mesebetsi e joalo.
Ho ea ka NVIDIA, ho tsamaisoa ha DGX A100 ho se ho qalile ka theko ea $ 199 ka kopi, balekane ba k'hamphani ba se ba ntse ba tšoara litsamaiso tsena ka lihlopha tsa bona tsa maru, ecosystem e se e akaretsa linaha tse 000, ho kenyeletsoa Vietnam le UAE. Ntle le moo, tharollo ea lits'oants'o tse nang le boqapi ba Ampere e tla ba karolo ea sistimi e kholo ea Perlmutter, e entsoeng ke Cray bakeng sa Lefapha la Matla la US. E tla ba le li-processor tsa graphics tsa NVIDIA Ampere hammoho le li-processor tse bohareng tsa AMD EPYC Milan tse nang le meralo ea Zen 26. Li-node tsa Supercomputer tse thehiloeng ho NVIDIA Ampere li tla fihla ho moreki halofong ea bobeli ea selemo, le hoja likopi tsa pele li se li fihlile laboratoring e khethehileng. lefapha la Amerika.
