Khatiso ea 54 ea lethathamo la li-supercomputer tse sebetsang hantle ka ho fetisisa li phatlalalitsoe

e hatisitsoeng Khatiso ea 54 tekanyetso Lik'homphieutha tse 500 tse sebetsang ka ho fetisisa lefatšeng. Khatisong e ncha, tse leshome tse holimo ha lia fetoha. Sehlopha se maemong a pele maemong Summit tsamaisitsoe ka IBM ho Oak Ridge National Laboratory (USA). Sehlopha se tsamaisa Red Hat Enterprise Linux mme se kenyelletsa li-processor cores tse limilione tse 2.4 (tse sebelisang 22-core IBM Power9 22C 3.07GHz CPUs le NVIDIA Tesla V100 accelerators), tse fanang ka ts'ebetso ea 148 petaflops.

Sehlopha sa Amerika se nka sebaka sa bobeli Sierra, e kentsoeng Livermore National Laboratory ke IBM motheong oa sethala se tšoanang le Seboka le ho bontša ts'ebetso ho li-petaflops tsa 94 (tse ka bang limilione tse 1.5).

Boemong ba boraro ke sehlopha sa Machaena Sunway TaihuLight, e sebetsang Setsing sa Naha sa Supercomputing sa Chaena, ho kenyelletsa le li-computing cores tse fetang limilione tse 10 le ho bonts'a ts'ebetso ea li-petaflops tse 93. Leha ho na le matšoao a ts'oanang a ts'ebetso, sehlopha sa Sierra se sebelisa halofo ea matla joalo ka Sunway TaihuLight.

Sebakeng sa bone ke sehlopha sa China sa Tianhe-2A, se kenyelletsang li-cores tse ka bang limilione tse 5 mme se bonts'a ts'ebetso ea li-petaflops tse 61.

Sehlopha se nka sebaka sa bohlano maemong Frontera, e hlahisitsoeng ke Dell bakeng sa Setsi sa Khomphutha sa Texas. Sehlopha se tsamaisa CentOS Linux 7 mme se kenyelletsa li-cores tse fetang likete tse 448 tse thehiloeng ho Xeon Platinum 8280 28C 2.7GHz. Kakaretso ea boholo ba RAM ke 1.5 PB, 'me ts'ebetso e fihla ho 23 petaflops, e leng makhetlo a 6 ka tlase ho moeta-pele oa tekanyo.

Mekhoa e khahlisang haholo:

  • Sehlopha se secha sa Russia se nkile sebaka sa 29 maemong SberCloud, e qalileng ke Sberbank. Sehlopha se hahiloe sethaleng sa NVIDIA DGX-2, se sebelisa Xeon Platinum 8168 24C 2.7GHz CPU 'me se na le li-cores tsa 99600 tsa computing. Ts'ebetso ea SberCloud ke li-petaflops tse 6.6. Sistimi ea ts'ebetso ke Ubuntu 18.04.01.

    Sehlopha sa bobeli sa lapeng, Lomonosov 2, se tlohile sebakeng sa bo6 ho ea ho sa 93 maemong a likhoeli tse 107. Sehlopha ka Roshydromet e theohile ho tloha ho 365 ho ea ho 465 sebaka.
