Purosesa yapakati inali yothamanga kangapo pakuchita bwino kuposa kuphatikiza ma processor azithunzi eyiti nthawi imodzi pophunzira mwakuya ma neural network. Zikumveka ngati chinachake chochokera m'nthano za sayansi, sichoncho? Koma ofufuza a Rice University, pogwiritsa ntchito Intel Xeon, atsimikizira kuti ndizotheka.
Ma GPU nthawi zonse amakhala oyenera kuphunzira mwakuya ma neural network kuposa ma CPU. Izi ndichifukwa cha kapangidwe ka ma GPU, omwe amakhala ndi ma cores ang'onoang'ono ambiri omwe amatha kugwira ntchito zing'onozing'ono zing'onozing'ono zofanana, zomwe ndizomwe zimafunikira pakuphunzitsa ma neural network. Koma zidapezeka kuti mapurosesa apakati, okhala ndi njira yoyenera, amatha kukhala othandiza kwambiri pakuphunzira mozama.
Akuti pogwiritsira ntchito SLIDE deep learning algorithm, purosesa ya Intel Xeon yokhala ndi ma cores 44 inali yopindulitsa nthawi 3,5 kuposa kuphatikiza ma accelerator asanu ndi atatu a NVIDIA Tesla V100. Aka ndi nthawi yoyamba kuti CPU singogwirana ndi GPU muzochitika zotere, komanso kuwaposa, komanso mowonekera kwambiri.
Kutulutsa kwa atolankhani komwe ku yunivesiteyo kunanena kuti ma algorithm a SLIDE safuna ma GPU chifukwa amagwiritsa ntchito njira yosiyana. Nthawi zambiri, pophunzitsa ma neural network, njira yolumikizira zolakwika zophunzitsira imagwiritsidwa ntchito, yomwe imagwiritsa ntchito kuchulukitsa kwa matrix, komwe ndi katundu wabwino kwa GPU. SLIDE, kumbali ina, imatembenuza kuphunzira kukhala vuto loyang'ana lomwe limathetsedwa pogwiritsa ntchito matebulo a hashi.
Malinga ndi ochita kafukufuku, izi zimachepetsa kwambiri mtengo wowerengera ma neural network. Kuti apeze zoyambira, ofufuzawo adagwiritsa ntchito labu ya Rice University lab yokhala ndi ma accelerator asanu ndi atatu a Tesla V100 kuti aphunzitse neural network pogwiritsa ntchito laibulale ya Google ya TensorFlow. Ntchitoyi inatenga maola 3,5. Pambuyo pake, neural network yofananira idaphunzitsidwa pogwiritsa ntchito algorithm ya SLIDE pamakina okhala ndi purosesa imodzi ya 44-core Xeon, ndipo idatenga ola limodzi lokha.
Ndizofunikira kudziwa apa kuti Intel pakadali pano ilibe mitundu 44-core processor pamapangidwe ake. N'zotheka kuti ochita kafukufuku anagwiritsa ntchito mtundu wina wa mwambo kapena chip chosatulutsidwa, koma izi sizingatheke. Ndizotheka kwambiri kuti makina okhala ndi ma 22-core Intel Xeons adagwiritsidwa ntchito pano, kapena panali cholakwika chabe pakutulutsa atolankhani, ndipo tikulankhula za ulusi 44 womwe unaperekedwa ndi purosesa imodzi ya 22-core. Koma mulimonse, izi sizimalepheretsa kupindula komweko.
Zachidziwikire, algorithm ya SLIDE iyenerabe kudutsa mayeso ambiri ndikuwonetsetsa kuti imagwira ntchito bwino, komanso kusakhalapo kwa zovuta zilizonse ndi zovuta. Komabe, zomwe tikuwona pano ndizochititsa chidwi kwambiri ndipo zimatha kukhala ndi zotsatira zazikulu pakukula kwamakampani.
