Incamake
Urutonde rukurikiranye rugabanya umurongo umwe muremure winjiza murwego rwa GPU nyinshi kurwego rwa token (igihe), kandi Impeta Yitondewe ireka izo GPU zibara kwitondera neza zinyuze urufunguzo / agaciro bahagaritse impeta. Hamwe na hamwe bakora miriyoni-token imiterere ya windows ishoboka nta GPU nimwe ifata urutonde rwose.
Ikurikiranyabihe hamwe no Kwitondera Impeta ni inyubako ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
Icyitonderwa gisanzwe gikeneye buri kibazo kugirango ubone urufunguzo / agaciro, bityo ibikorwa byo kwibuka bikura hamwe nuburebure bwikurikiranya kandi K / V yuzuye igomba kuboneka. Ikigereranyo kibangikanye kigabanya urukurikirane kuburyo buri GPU ifite igice gihuza ibimenyetso (nibibazo byabo, urufunguzo, indangagaciro). Impeta yitondere noneho itondekanya GPU mumpeta yumvikana: buri gikoresho gikomeza ibibazo byaho bikosorwa mugihe K / V zahagaritswe hop-by-hop kuzenguruka impeta. Mugihe buri gice kigeze, GPU ibara kwitondera igice kandi ikusanya ibisubizo ukoresheje interineti-softmax (kimwe na max / sum trick nka FlashAttention). Nyuma yumuzingo wuzuye, buri kibazo cyitabiriye urufunguzo rwose, nta GPU yigeze ibika K / V. Byibanze, itumanaho rya K / V ryuzuzanya no kubara, bityo ryongeraho igiciro gito cyurukuta-isaha.
Ubushishozi
Impeta Kwitondera gushingira kuri softmax kumurongo: kwitabwaho birashobora kubarwa guhagarika-guhagarika mugihe ukomeza gukora ntarengwa hamwe nogukora ibisanzwe, hanyuma ugakuraho amafaranga igice cyambere mugihe agaciro kanini kagaragaye. Ibi bituma ibisubizo bibarwa muburyo bwo kwitabwaho byuzuye. Impeta inyura gusa kuri K / V (umunzani ufite ubunini, ntabwo ari urukurikirane rwuzuye), kandi kubera ko itumanaho rya buri hop ryuzuzanya na matmul yabanjirije iyi, umurongo mugari - ntabwo ari kwibuka - bihinduka ibintu bigabanya imipaka.
Kumenya Urutonde Kuringaniza no Kwitonda Impeta
Urutonde rukurikiranye rugabanya umurongo umwe muremure winjiza murwego rwa GPU nyinshi kurwego rwa token (igihe), kandi Impeta Yitondewe ireka izo GPU zibara kwitondera neza zinyuze urufunguzo / agaciro bahagaritse impeta. Hamwe na hamwe bakora miriyoni-token imiterere ya windows ishoboka nta GPU nimwe ifata urutonde rwose. Ikurikiranyabihe hamwe no Kwitondera Impeta ni inyubako ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugira ngo usobanukirwe byimbitse, fata Urutonde rukurikiranye hamwe nimpeta yitonderwa nkicyitegererezo gikora, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mubimenyerezo, amatsinda akomeye akoresha Urutonde rukurikirana hamwe nimpeta Yitondewe yubaka imyubakire, amakuru, hamwe nibikorwa remezo birwanya kwizerwa nigiciro. Bandika ibipimo ngenderwaho byerekana intsinzi, bagerageza kurwanya amakuru afatika hamwe nakazi keza, kandi bagasubiramo bashingiye kubikorwa byagaragaye ko batsinzwe aho gutsinda inshuro imwe. Aha niho imyumvire yubumenyi ihinduka mubushobozi burambye kubicuruzwa, politiki, nibikorwa.
Ibyemezo byubwubatsi bitwara imikorere nigiciro cyimikorere kumyaka. Mugihe kimwe, Guhindura igipimo kimwe gishobora guhisha intege nke za sisitemu. Uburyo bukomeye cyane ni uguhuza umuvuduko wikigereranyo hamwe na disipuline yimiyoborere: kuyobora abaderevu, gufata ibimenyetso, gutangaza ibyemezo byicyemezo, no gukomeza kuvugurura uburyo bwo kwirinda nkimyitwarire yicyitegererezo, ibyo abakoresha bategereje, nibisabwa n'amategeko bigenda bihinduka.
