Incamake
Ubwubatsi bukora bugabanya imvugo nini yerekana urugero mubice bibiri bitandukanye - prefill na decode - ikanabikoresha kubidendezi bitandukanye bya GPU. Ntacyo bitwaye kuko ibyo byiciro byombi bifite ubushake buke bwibikoresho, kandi kubahatira kumashini imwe isesagura ubushobozi kandi bikababaza ubukererwe.
Gutandukanya Prefill na Decode Gukora ni tekinoroji ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
Iyo LLM isubije, ikora mubyiciro bibiri. Prefill isoma icyarimwe icyarimwe hanyuma yubake urufunguzo-agaciro (KV) cache; iyi nini nini, ibangikanye, kubara-guturika kuzuza ibice byimibare ya GPU. Decode noneho itanga ibimenyetso kimwekimwe, buri ntambwe isoma cache yose ya KV-yibuka-umurongo-wuzuye, uhuza-kubara. Kwiruka hamwe, prefill ndende ihagarika decode ya buriwese (umutwe-wumurongo uhagarika), kandi gukubita byombi bitera kwivanga. Gutandukana bishyira prefill kuri pisine imwe ya GPU hanyuma ukarangiza kurindi, kwimura cache cache hagati yabo hejuru yimikoranire yihuse nka NVLink cyangwa InfiniBand. Buri kidendezi cyarateguwe kandi gipimwa mu bwigenge, kunoza ibicuruzwa byiza, koroshya umurizo, no kureka ababikora bagakubita igihe-kuri-mbere-ikimenyetso-nigihe-cyo-gusohora-icyerekezo icyarimwe.
Ubushishozi
Ibyiciro byombi biratandukanye muburyo bwabo. Kuzuza ibintu byose byihutirwa muburyo bubangikanye, nuko FLOPs igipimo cyayo hamwe nuburebure bwihuse kandi ikarenza tensor cores. Decode ni autoregressive: buri kimenyetso gishya gikenera inzira imwe yimbere yongeye gusoma kashe yuzuye ya KV kuva HBM, bityo ibyinjira byinjizwa numuyoboro mugari, ntabwo ubara. Gutandukana kubikoresha mugupima, gutobora, ndetse no guhitamo kubangikanya kuri buri kidendezi, hanyuma kohereza cache cache kuva kubakozi bambere kugeza kubakozi.
Kumenyereza Byuzuye Byuzuye Byuzuye na Decode Gukora
Ubwubatsi bukora bugabanya imvugo nini yerekana urugero mubice bibiri bitandukanye - prefill na decode - ikanabikoresha kubidendezi bitandukanye bya GPU. Ntacyo bitwaye kuko ibyo byiciro byombi bifite ubushake buke bwibikoresho, kandi kubahatira kumashini imwe isesagura ubushobozi kandi bikababaza ubukererwe. Gutandukanya Prefill na Decode Gukora ni tekinoroji ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake byimbitse, fata Prefgregated Prefill na Decode Gukora nkicyitegererezo cyibikorwa, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mu myitozo, amakipe akomeye akoresha Prefgregated Prefill na Decode Gukora neza uburyo bwubaka, 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.
