Lub hauv paus processor yog ob peb zaug hauv kev ua tau zoo dua li kev sib xyaw ntawm yim lub processors ib zaug thaum sib sib zog nqus kawm neural networks. Suab zoo li ib yam dab tsi tawm ntawm science ntawv tseeb, puas yog? Tab sis cov kws tshawb fawb los ntawm Rice University, siv Intel Xeon, tau ua pov thawj tias nws muaj peev xwm.
GPUs yeej ib txwm ua tau zoo dua rau kev kawm sib sib zog nqus neural networks dua li CPUs. Qhov no yog vim lub architecture ntawm GPUs, uas muaj ntau lub cores me me uas muaj peev xwm ua tau ntau yam haujlwm me me nyob rau tib lub sijhawm, uas yog qhov yuav tsum tau ua rau kev cob qhia neural networks. Tab sis nws tau pom tias cov txheej txheem hauv nruab nrab, nrog rau txoj hauv kev zoo, tuaj yeem ua tau zoo heev hauv kev kawm tob.
Nws tau tshaj tawm tias thaum siv SLIDE sib sib zog nqus kev kawm algorithm, Intel Xeon processor nrog 44 cores yog 3,5 npaug ntau dua ua tau zoo dua li kev sib xyaw ntawm yim NVIDIA Tesla V100 suav accelerators. Qhov no yog thawj zaug uas CPU tsis tsuas yog ntes tau nrog GPU hauv qhov xwm txheej zoo li no, tab sis kuj tau tshaj lawv, thiab pom tau zoo heev.
Ib tsab xov xwm tshaj tawm los ntawm lub tsev kawm ntawv hais tias SLIDE algorithm tsis xav tau GPUs vim nws siv txoj hauv kev sib txawv kiag li. Feem ntau, thaum kev cob qhia neural tes hauj lwm, kev cob qhia yuam kev backpropagation txheej txheem yog siv, uas siv matrix multiplication, uas yog ib tug zoo tagnrho load rau GPU. SLIDE, ntawm qhov tod tes, hloov kev kawm mus rau hauv qhov teeb meem nrhiav kev daws teeb meem uas siv cov lus hash.
Raws li cov kws tshawb fawb, qhov no txo ββqis tus nqi ntawm kev cob qhia neural networks. Txhawm rau kom tau txais cov hauv paus ntsiab lus, cov kws tshawb fawb siv Rice University lab tus txheej txheem uas twb muaj lawm nrog yim Tesla V100 accelerators los cob qhia lub network neural siv Google lub tsev qiv ntawv TensorFlow. Cov txheej txheem siv sijhawm 3,5 teev. Tom qab ntawd, qhov zoo sib xws neural network tau raug cob qhia siv SLIDE algorithm ntawm lub kaw lus nrog ib leeg 44-core Xeon processor, thiab nws siv sijhawm li 1 teev xwb.
Nws tsim nyog sau cia ntawm no tias Intel tam sim no tsis muaj 44-core processor qauv hauv nws cov khoom lag luam. Nws yog qhov ua tau tias cov kws tshawb fawb tau siv qee yam kev cai lossis tsis tau tso tawm nti, tab sis qhov no tsis zoo li. Nws yog qhov zoo dua tias lub kaw lus nrog ob 22-core Intel Xeons tau siv ntawm no, lossis tsuas yog muaj qhov yuam kev hauv kev tshaj tawm, thiab peb tab tom tham txog 44 xov uas tau muab los ntawm ib qho 22-core processor. Tab sis nyob rau hauv txhua rooj plaub, qhov no tsis cuam tshuam los ntawm kev ua tiav nws tus kheej.
Tau kawg, SLIDE algorithm tseem yuav tsum dhau los ntawm ntau qhov kev sim thiab ua pov thawj nws cov txiaj ntsig, nrog rau qhov tsis muaj qhov tshwj xeeb thiab qhov tsis zoo. Txawm li cas los xij, qhov peb pom tam sim no yog qhov zoo heev thiab tuaj yeem muaj kev cuam tshuam loj rau kev txhim kho kev lag luam.
