Lwm tiam NVIDIA GPUs yuav nce mus txog 75% sai dua Volta

Cov tiam tom ntej ntawm NVIDIA GPUs, zoo li hu ua Ampere, yuav muab cov txiaj ntsig tseem ceeb ntawm cov kev daws teeb meem tam sim no, The Next Platform qhia. Muaj tseeb, peb tab tom tham txog cov txheej txheem duab siv hauv kev suav accelerators.

Kev suav cov accelerators ntawm cov tiam tshiab NVIDIA GPUs yuav siv rau hauv Big Red 200 supercomputer ntawm Indiana University (USA), ua rau ntawm Cray Shasta platform. Lawv yuav muab ntxiv rau hauv lub caij ntuj sov no thaum lub sij hawm thib ob ntawm kev tsim kho lub supercomputer.

Tam sim no, nws tsis tau hais tias GPUs cov no yuav yog dab tsi, vim tias NVIDIA tseem tsis tau nthuav tawm lawv, tab sis pom tau tias peb tab tom tham txog lub cim tshiab ntawm Tesla accelerators raws li Ampere. Nws zoo li NVIDIA yuav tshaj tawm tiam tshiab ntawm nws cov GPUs hauv lub Peb Hlis ntawm nws tus kheej qhov kev tshwm sim TSI 2020, thiab tom qab ntawd cov accelerators tshiab raws li lawv yuav tsum tau npaj rau lub caij ntuj sov.

Nws tau tshaj tawm tias Loj Liab 200 system tau pib npaj los nruab nrog Tesla V100 accelerators tam sim no ntawm NVIDIA Volta GPUs. Qhov no yuav tso cai rau lub supercomputer kom ua tiav qhov ua tau zoo ntawm 5,9 Pflops. Txawm li cas los xij, tom qab ntawd nws tau txiav txim siab tos me ntsis, faib kev tsim kho ntawm Big Red 200 ua ob theem, thiab siv cov tsuj roj tshiab.

Thaum thawj theem ntawm kev tsim kho, lub kaw lus ntawm 672 dual-processor pawg tau tsim raws li 64-core AMD Epyc 7742 tiam Rome processors. Lub sijhawm thib ob suav nrog qhov sib ntxiv ntawm Epyc Rome-based nodes tshiab, uas yuav tau nruab nrog ib lossis ntau lub cim ntxiv NVIDIA GPUs. Raws li qhov tshwm sim, qhov kev ua tau zoo ntawm Loj Liab 200 yuav ncav cuag 8 Pflops, thiab tib lub sijhawm tsawg dua GPU accelerators yuav raug siv dua li kev npaj.

Nws hloov tawm tias qhov kev ua tau zoo ntawm lub cim tshiab ntawm GPUs yuav yog 70-75% siab dua piv rau Volta. Tau kawg, qhov no cuam tshuam qhov kev ua tau zoo "liab qab" hauv kev ua haujlwm ib leeg (FP32). Yog li, tam sim no nws nyuaj rau hais tias cov lus hais txog qhov kev nce qib hauv kev ua tau zoo li cas rau cov tiam tshiab GeForce cov neeg siv khoom video. Cia peb cia siab tias cov neeg siv khoom nruab nrab kuj tseem yuav tau txais GPUs muaj zog dua.
