54th ib tsab ntawm cov npe ntawm cov kev ua tau zoo tshaj plaws supercomputers tau luam tawm

luam tawm 54th lus kev ntsuas 500 feem ntau cov khoos phis tawj ua tau zoo hauv ntiaj teb. Hauv qhov teeb meem tshiab, kaum sab saum toj tsis tau hloov pauv. Cov pawg yog nyob rau hauv thawj qhov chaw nyob rau hauv qeb duas qhov ua siab tshaj xa mus los ntawm IBM ntawm Oak Ridge National Laboratory (USA). Cov pawg khiav Red Hat Enterprise Linux thiab suav nrog 2.4 lab processor cores (siv 22-core IBM Power9 22C 3.07GHz CPUs thiab NVIDIA Tesla V100 accelerators), uas muab kev ua haujlwm ntawm 148 petaflops.

Cov pawg neeg Asmeskas tau txais qhov thib ob Sierra, tau teeb tsa ntawm Livermore National Laboratory los ntawm IBM los ntawm lub hauv paus ntawm lub platform zoo ib yam li Summit thiab ua kom pom kev ua tau zoo ntawm 94 petaflops (txog 1.5 lab cores).

Qhov thib peb yog pawg Suav Sunway TaihuLight, kev khiav hauj lwm ntawm National Supercomputing Center ntawm Tuam Tshoj, suav nrog ntau tshaj 10 lab lub computer cores thiab qhia txog kev ua tau zoo ntawm 93 petaflops. Txawm hais tias qhov ntsuas tau zoo sib xws, Sierra pawg siv ib nrab ntawm lub zog ntau npaum li Sunway TaihuLight.

Hauv qhov chaw thib plaub yog Suav Tianhe-2A pawg, uas suav nrog yuav luag 5 lab cores thiab ua kom pom qhov ua tau zoo ntawm 61 petaflops.

Cov pawg yuav siv qhov chaw thib tsib hauv qeb duas Frontera, tsim los ntawm Dell rau Texas Computer Center. Cov pawg khiav CentOS Linux 7 thiab suav nrog ntau dua 448 txhiab cores raws li Xeon Platinum 8280 28C 2.7GHz. Tag nrho qhov loj me ntawm RAM yog 1.5 PB, thiab kev ua tau zoo nce mus txog 23 petaflops, uas yog 6 npaug tsawg dua tus thawj coj hauv kev ntaus nqi.

Qhov nthuav tshaj plaws tiam sis:

  • Cov pab pawg neeg Lavxias tshiab tau coj 29 qhov chaw hauv qeb duas SberCloud, launched los ntawm Sberbank. Cov pawg yog tsim los ntawm NVIDIA DGX-2 platform, siv Xeon Platinum 8168 24C 2.7GHz CPU thiab muaj 99600 suav cores. SberCloud kev ua tau zoo yog 6.6 petaflops. Lub operating system yog Ubuntu 18.04.01.

    Qhov thib ob domestic pawg, Lomonosov 2, tsiv los ntawm 6rd mus rau 93th qhov chaw nyob rau hauv qeb duas 107 lub hlis. Pawg hauv Roshydromet poob los ntawm 365 mus rau 465 qhov chaw. Tus naj npawb ntawm cov pab pawg hauv tsev nyob rau hauv qeb duas rau lub hlis nce ntawm 2 txog 3 (hauv 2017 muaj 5 domestic systems, thiab hauv 2012 - 12);

  • Kev faib tawm los ntawm tus naj npawb ntawm supercomputers hauv ntau lub teb chaws:
    • Tuam Tshoj: 228 (219 rau lub hlis dhau los). Nyob rau hauv tag nrho, Suav pawg tsim tawm 31.9% ntawm tag nrho cov khoom tsim tau (rau lub hlis dhau los - 29.9%);
    • USA: 117 (116). Tag nrho cov khoom tsim tau kwv yees li ntawm 37.8% (ib xyoos dhau los - 38.4%);

    • Singapore 4 (5);
    • Australia, Kaus Lim Qab Teb, Saudi Arabia, Brazil, Russia: 3;
  • Nyob rau hauv qeb duas ntawm kev khiav hauj lwm systems siv nyob rau hauv supercomputers, tsuas yog Linux tau nyob rau ob thiab ib nrab xyoo;
  • Kev faib tawm los ntawm Linux kev faib tawm (hauv kab ke - 6 lub hlis dhau los):
    • 49.6% (48.8%) tsis qhia txog kev faib khoom,
    • 26.4% (27.8%) siv CentOS,
    • 6.8% (7.6%) - Cray Linux,
    • 4.8% (4.8%) - RHEL,
    • 3% (3%) - SUSE,
    • 2% (1.6%) - Ubuntu;
    • 0.4% (0.4%) - Kev tshawb fawb Linux
  • Qhov tsawg kawg nkaus kev ua tau zoo rau kev nkag mus rau Top500 hauv 6 lub hlis tau nce los ntawm 1022 mus rau 1142 teraflops (xyoo tas los, tsuas yog 272 pawg tau pom qhov ua tau zoo tshaj li petaflop, ob xyoos dhau los - 138, peb xyoos dhau los - 94). Rau Top100, qhov pib nkag tau nce los ntawm 2395 txog 2570 teraflops;
  • Tag nrho cov kev ua tau zoo ntawm txhua lub tshuab hauv qhov kev ntsuam xyuas tau nce ntau xyoo dhau los ntawm 1.559 rau 1.650 exaflops (peb xyoos dhau los nws yog 566 petaflops). Lub kaw lus kaw qhov qeb duas tam sim no yog nyob rau hauv 397th qhov chaw nyob rau hauv qhov teeb meem kawg, thiab 311th nyob rau hauv lub xyoo ua ntej;
  • Kev faib tawm dav dav ntawm tus naj npawb ntawm supercomputers nyob rau hauv ntau qhov chaw ntawm lub ntiaj teb no yog raws li nram no:
    274 supercomputer nyob rau hauv Asia (267 - rau lub hlis dhau los),
    129 hauv Asmeskas (127) thiab 94 hauv Tebchaws Europe (98), 3 hauv Oceania;

  • Raws li lub hauv paus processor, Intel CPUs nyob rau hauv cov hlau lead - 94% (rau lub hlis dhau los nws yog 95.6%), nyob rau hauv thib ob qhov chaw yog IBM zog - 2.8% (los ntawm 2.6%), nyob rau hauv peb qhov chaw yog AMD - 0.6% (0.4% ), nyob rau hauv plaub qhov chaw yog SPARC64 - 0.6% (0.8%);
  • 35.6% (rau lub hlis dhau los 33.2%) ntawm tag nrho cov siv processors muaj 20 cores, 13.8% (16.8%) - 16 cores, 11.2% (11.2%) - 12 cores, 11% (11.2%) - 18 cores, 7.8% ( 7%) - 14 cores;
  • 144 tawm ntawm 500 lub tshuab (rau lub hlis dhau los - 133) ntxiv rau siv accelerators lossis coprocessors, thaum 135 lub tshuab siv NVIDIA chips (rau lub hlis dhau los muaj 125), 5 - Intel Xeon Phi (muaj 5), 1 - PEZY (1) , 1 siv cov kev daws teeb meem hybrid (muaj 1), 1 siv Matrix-2000 (1), 1 AMD Vega GPU (XNUMX lub hlis dhau los AMD accelerators tsis tau siv);
  • Ntawm cov tuam txhab lag luam, Lenovo tau ua thawj qhov chaw - 34.8% (ib xyoos dhau los 34.6%), qhov thib ob
    Sugon coj tus thawj coj nrog 14.2% (12.6%), Inspur coj qhov chaw thib peb - ​​13.2% (14.2%), plaub qhov chaw yog Hewlett-Packard - 7% (8%) thiab 7% (7.8%), ua raws li Atos - 4.6%, IBM 2.6 (2.4%), Fujitsu 2.6% (2.6%), Penguin Computing - 2.2% (1.8%), Dell EMC 2.2% (3%), Huawei 2% (1.4%), NVIDIA 1.2%. Tsib xyoos dhau los, kev faib tawm ntawm cov tuam txhab lag luam yog raws li hauv qab no: Hewlett-Packard 36%, IBM 35%, Cray 10.2% thiab SGI 3.8%;

  • Ethernet yog siv los txuas cov nodes hauv 52% ntawm pawg, InfiniBand yog siv hauv 28% ntawm pawg, thiab Omnipath yog siv hauv 10%.

    Thaum saib tag nrho cov kev ua tau zoo, InfiniBand-based systems account rau 40% ntawm Top500 qhov kev ua tau zoo tag nrho, thaum Ethernet suav rau 29%.

Nyob rau tib lub sijhawm, qhov kev tso tawm tshiab ntawm kev ntsuas lwm qhov ntawm pawg kab ke muaj Daim duab 500, tsom rau kev ntsuam xyuas kev ua tau zoo ntawm supercomputer platforms cuam tshuam nrog simulating cov txheej txheem ntawm lub cev thiab cov dej num rau kev ua cov ntaub ntawv loj loj rau cov tshuab zoo li no. Kev ntsuas Green500 cais ntau dua tsis tso tawm thiab merged nrog Top500, raws li lub zog efficiency yog tam sim no xav txog nyob rau hauv lub ntsiab Top500 ntsuam xyuas (qhov piv ntawm LINPACK FLOPS rau lub hwj chim noj nyob rau hauv watts yog muab rau hauv tus account).
