Uhlelo lwama-54 lohlu lwamakhompiyutha amakhulu asebenza kahle kakhulu lushicilelwe

eshicilelwe Isiqephu 54 ukukala Amakhompyutha angu-500 asebenza kahle kakhulu emhlabeni. Kumagazini omusha, abayishumi abaphezulu abakashintshi. Iqoqo lisendaweni yokuqala ohlwini Summit kumisiwe ngu-IBM e-Oak Ridge National Laboratory (USA). Iqoqo lisebenzisa i-Red Hat Enterprise Linux futhi lihlanganisa ama-processor cores ayizigidi ezingu-2.4 (esebenzisa ama-22-core IBM Power9 22C 3.07GHz CPUs nama-accelerator e-NVIDIA Tesla V100), ahlinzeka ngokusebenza kwama-petaflops angu-148.

Iqoqo laseMelika lithatha indawo yesibili Sierra, efakwe e-Livermore National Laboratory yi-IBM ngesisekelo seplatifomu efana neNgqungquthela futhi ebonisa ukusebenza kuma-petaflops angu-94 (cishe ama-cores ayizigidi ezingu-1.5).

Endaweni yesithathu yiqoqo lamaShayina Sunway TaihuLight, esebenza e-National Supercomputing Center yase-China, okuhlanganisa amakhompiyutha angaphezu kwezigidi ezingu-10 futhi ebonisa ukusebenza kwama-petaflops angu-93. Ngaphandle kwezinkomba zokusebenza ezifanayo, iqoqo laseSierra lisebenzisa uhhafu wamandla njengeSunway TaihuLight.

Endaweni yesine kukhona iqoqo le-Chinese Tianhe-2A, elihlanganisa cishe ama-cores ayizigidi ezingu-5 futhi libonisa ukusebenza kwama-petaflops angu-61.

Iqoqo lithatha indawo yesihlanu ohlwini Frontera, ekhiqizwe nguDell we-Texas Computer Center. Iqoqo lisebenzisa i-CentOS Linux 7 futhi lihlanganisa ama-cores angaphezu kwezinkulungwane ezingama-448 ngokusekelwe ku-Xeon Platinum 8280 28C 2.7GHz. Isamba sikasayizi we-RAM ngu-1.5 PB, futhi ukusebenza kufinyelela kuma-petaflops angu-23, okungaphansi izikhathi ezingu-6 kunomholi esilinganisweni.

Amathrendi athakasela kakhulu:

  • Iqoqo elisha laseRussia lithathe indawo yama-29 ohlwini I-SberCloud, eyethulwe ngabakwaSberbank. Iqoqo lakhiwe kuplathifomu ye-NVIDIA DGX-2, lisebenzisa i-Xeon Platinum 8168 24C 2.7GHz CPU futhi linama-computing cores angu-99600. Ukusebenza kwe-SberCloud yi-6.6 petaflops. Uhlelo lokusebenza Ubuntu 18.04.01.

    Iqoqo lesibili lasekhaya, iLomonosov 2, lisuke endaweni yama-6 laya endaweni ye-93 endaweni yezinyanga eziyisi-107. Iqoqo phakathi I-Roshydromet lehle lisuka ku-365 laya ku-465 endaweni. Inani lamaqoqo asekhaya asezingeni ezinyangeni eziyisithupha lenyuke lisuka ku-2 laya ku-3 (ngowezi-2017 lalingu-5 izinhlelo zasekhaya, futhi ngo-2012 - 12);

  • Ukusatshalaliswa ngenombolo yamakhompyutha amakhulu emazweni ahlukene:
    • I-China: 228 (219 ezinyangeni eziyisithupha ezedlule). Sekukonke, amaqoqo aseShayina akhiqiza i-31.9% yawo wonke umkhiqizo (izinyanga eziyisithupha ezedlule - 29.9%);
    • E-USA: 117 (116). Ukukhiqiza okuphelele kulinganiselwa ku-37.8% (onyakeni odlule - 38.4%);
    • EJapane: 29 (29);
    • eFrance: 18 (19);
    • EJalimane: 16 (14);
    • E-Netherlands: 15 (13);
    • I-Ireland: 14 (13);
    • E-UK: 11 (18);
    • eCanada 9 (8);
    • I-Italy: 5 (5);
    • Singapore 4 (5);
    • I-Australia, iNingizimu Korea, iSaudi Arabia, iBrazil, iRussia: 3;
  • Esilinganisweni sezinhlelo zokusebenza ezisetshenziswa kuma-supercomputers, i-Linux kuphela esele iminyaka emibili nengxenye;
  • Ukusatshalaliswa ngokusatshalaliswa kwe-Linux (kubakaki - izinyanga eziyi-6 ezedlule):
    • U-49.6% (48.8%) awunayo imininingwane yokusabalalisa,
    • U-26.4% (27.8%) usebenzisa i-CentOS,
    • 6.8% (7.6%) - Cray Linux,
    • 4.8% (4.8%) - RHEL,
    • 3% (3%) - SUSE,
    • 2% (1.6%) - Ubuntu;
    • 0.4% (0.4%) - I-Linux Yesayensi
  • Umkhawulo omncane wokusebenza wokungena ku-Top500 ezinyangeni eziyisi-6 ukhuphuke usuka ku-1022 waya ku-1142 teraflops (ngonyaka odlule, amaqoqo angama-272 kuphela abonise ukusebenza okungaphezu kwe-petaflop, eminyakeni emibili edlule - 138, eminyakeni emithathu edlule - 94). Ku-Top100, umkhawulo wokungena ukhuphuke ukusuka ku-2395 kuya ku-2570 teraflops;
  • Ukusebenza okuphelele kwawo wonke amasistimu esilinganisweni kukhuphuke phakathi nonyaka ukusuka ku-1.559 kuya ku-1.650 ama-exaflops (eminyakeni emithathu edlule bekungama-petaflops angama-566). Uhlelo oluvala izinga lamanje lwalusendaweni yama-397 kumagazini wokugcina, kanye ne-311 ngonyaka owandulele;
  • Ukusatshalaliswa okujwayelekile kwenani lama-supercomputers ezingxenyeni ezihlukene zomhlaba kungokulandelayo:
    274 supercomputer itholakala e-Asia (267 - izinyanga eziyisithupha ezedlule),
    abangu-129 eMelika (127) nabangu-94 eYurophu (98), 3 e-Oceania;

  • Njengesisekelo sokucubungula, ama-Intel CPU ahamba phambili - 94% (ezinyangeni eziyisithupha ezedlule bekungu-95.6%), endaweni yesibili i-IBM Power - 2.8% (kusuka ku-2.6%), endaweni yesithathu i-AMD - 0.6% (0.4% ), endaweni yesine ngu-SPARC64 - 0.6% (0.8%);
  • U-35.6% (ezinyangeni eziyisithupha ezedlule u-33.2%) wawo wonke ama-processor anama-cores angu-20, 13.8% (16.8%) - 16 cores, 11.2% (11.2%) - 12 cores, 11% (11.2%) - 18 cores, 7.8% ( 7%) - 14 cores;
  • Amasistimu angu-144 kwangu-500 (ezinyangeni eziyisithupha ezedlule - 133) aphinde asebenzise ama-accelerator noma ama-coprocessors, kuyilapho amasistimu angu-135 esebenzisa ama-NVIDIA chips (ezinyangeni eziyisithupha ezedlule abengu-125), 5 - Intel Xeon Phi (bekukhona 5), ​​1 - PEZY (1) , i-1 isebenzisa izixazululo ze-hybrid (kwakukhona 1), i-1 isebenzisa i-Matrix-2000 (1), i-1 AMD Vega GPU (izinyanga ezingu-XNUMX ezedlule ama-accelerator e-AMD awazange asetshenziswe);
  • Phakathi kwabakhiqizi bamaqoqo, uLenovo wathatha indawo yokuqala - 34.8% (onyakeni odlule 34.6%), indawo yesibili
    USugon uhambe phambili ngo-14.2% (12.6%), i-Inspur ithathe indawo yesithathu - 13.2% (14.2%), indawo yesine ithathwe nguHewlett-Packard - 7% (8%) no-7% (7.8%), elandelwa ngu-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%. Eminyakeni emihlanu edlule, ukusatshalaliswa phakathi kwabakhiqizi kwakungokulandelayo: Hewlett-Packard 36%, IBM 35%, Cray 10.2% kanye ne-SGI 3.8%;

  • I-Ethernet isetshenziselwa ukuxhuma ama-node ku-52% wamaqoqo, i-InfiniBand isetshenziswa ku-28% wamaqoqo, kanti i-Omnipath isetshenziswa ku-10%.

    Uma ubheka ukusebenza sekukonke, amasistimu asuselwa ku-InfiniBand athatha u-40% weTop500 yonke yokusebenza, kuyilapho i-Ethernet yenza ama-29%.

Ngesikhathi esifanayo, ukukhishwa okusha kwesinye isilinganiso sezinhlelo zeqoqo kuyatholakala Igrafu 500, egxile ekuhloleni ukusebenza kwezinkundla zamakhompiyutha amakhulu ahlobene nokulingisa izinqubo ezingokoqobo nemisebenzi yokucubungula amanani amakhulu edatha evamile kumasistimu anjalo. Isilinganiso I-Green500 ngokwehlukana ngaphezulu engakhululwa futhi ihlanganiswe ne-Top500, njengoba kusenjalo ukusebenza kahle kwamandla kubonakala esilinganisweni esiyinhloko se-Top500 (isilinganiso se-LINPACK FLOPS ekusetshenzisweni kwamandla kuma-watts siyacatshangelwa).
