Uhlolojikelele
Ukufana kochwepheshe kuhlukanisa 'ochwepheshe' abaningi bemodeli ye-Mixture-of-Experts kuwo wonke ama-GPU ahlukene ukuze idivayisi ngayinye ibambe ucezu lwamapharamitha kuphela. Kuyisihluthulelo sokusebenzisa amamodeli we-MoE we-trillion-parameter ngemali ephansi, njengoba ochwepheshe abambalwa kuphela abasebenzisa ithokheni ngayinye.
I-Expert Parallelism for MoE Serving iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yamamodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Isendlalelo se-Mixture-of-Experts (MoE) singena esikhundleni senethiwekhi eyodwa enkulu yokuphakelayo neziningi ezincane (ochwepheshe) kanye nerutha ekhetha ochwepheshe abaphezulu (okuvame ukuba ngu-1 noma 2) ngethokheni ngayinye. I-Expert parallelism (EP) ibeka ochwepheshe abahlukene kuma-GPU ahlukene. Uma kucatshangelwa, i-router inquma ukuthi yiluphi ochwepheshe oludinga ithokheni ngayinye, bese isinyathelo sokuxhumana sishova amathokheni kuma-GPU aphethe ochwepheshe abawakhethile, iqhube i-FFN, bese ishova imiphumela ibuye. Lokhu kuvumela imodeli ibe nengqikithi yemingcele emikhulu (incane) kuyilapho isebenzisa ingxenye encane kuphela yethokheni ngayinye (ama-FLOP aphansi). Amamodeli afana ne-Mixtral 8x7B, i-DeepSeek-V3, ne-GPT-OSS asebenzisa lokhu. Izingxenye eziqinile ziyi-load balancing kubo bonke ochwepheshe kanye nama-hops amabili abiza konke ukuya kukho konke isendlalelo ngasinye.
I-Technical Insight
Umakhenikha oyinhloko amaqoqo amabili okuhlanganisa konke kuya kukho konke kusendlalelo ngasinye se-MoE: thumela (thumela amathokheni kochwepheshe bawo) futhi uhlanganise (qoqa imiphumela emuva). Ngenxa yokuthi umzila uncike kudatha, inani lamathokheni ashaya uchwepheshe ngamunye liyahlukahluka, okubangela ukungalingani komthwalo kanye 'nama-stragglers.' Amasistimu wokunikeza isevisi engeza izici zamandla, izibhafa zochwepheshe, nokuwisa amathokheni noma ukuphediswa ukuze kugcinwe ama-GEMM (i-matrix iphindaphinda) umfaniswano, futhi ngokuvamile adlulela kukho konke ukuxhumana nezibalo zochwepheshe ukuze kufihlwe ukubambezeleka.
I-Mastering Expert Parallelism Yokusebenzela i-MoE
Ukufana kochwepheshe kuhlukanisa 'ochwepheshe' abaningi bemodeli ye-Mixture-of-Experts kuwo wonke ama-GPU ahlukene ukuze idivayisi ngayinye ibambe ucezu lwamapharamitha kuphela. Kuyisihluthulelo sokusebenzisa amamodeli we-MoE we-trillion-parameter ngemali ephansi, njengoba ochwepheshe abambalwa kuphela abasebenzisa ithokheni ngayinye. I-Expert Parallelism for MoE Serving iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yamamodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-Expert Parallelism ye-MoE Esebenza njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho uhlelo olungakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Expert Parallelism ye-MoE Serving athuthukisa ukukhetha kwezakhiwo, idatha, kanye nengqalasizinda ngokumelene nokuthembeka nezindleko. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
Izinqumo zezakhiwo ziqhuba ukusebenza kanye nezindleko zokusebenza iminyaka. Ngesikhathi esifanayo, Ukuthuthukisa ibhentshimakhi eyodwa kungafihla ubuthakathaka obubanzi besistimu. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
