Uhlolojikelele
I-Flash Attention iyindlela ehlakaniphile yokubala isinyathelo sokunaka ngaphakathi kwe-Transformers ngaphandle kokubhala i-matrix enkulu yokunaka ukuze ubambezele inkumbulo. Kwenza amamodeli womongo omude asheshe kakhulu futhi asebenzise inkumbulo kahle ngaphandle kokushintsha izibalo zawo.
I-Flash Attention iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Ukunaka okujwayelekile kuqhathanisa yonke ithokheni nawo wonke amanye amathokheni, okukhiqiza i-matrix yesikolo se-N-by-N ekhula ngokuphindwe kane ngobude bokulandelana. Ngokungazi, leyo matrix ibhalelwe futhi ifundwe emuva kumemori yomkhawulokudonsa ophezulu we-GPU (HBM), futhi lokho kuvalwa - hhayi ukuphindaphindeka - kuyibhodlela langempela. I-Flash Attention, eyethulwe u-Tri Dao nozakwabo ngo-2022, ihlela kabusha ukubala ukuze i-matrix ingalokothi igcinwe ngokugcwele. Icubungula imibuzo, okhiye, kanye namanani kuthayela amancane alingana ku-chip esheshayo ye-SRAM, ihlanganisa imiphumela engaphelele, futhi iwahlanganise ndawonye kusetshenziswa iqhinga le-inthanethi eligijima-softmax. Okukhiphayo kuyafana ngokwezibalo nokunaka okuvamile kodwa kusebenzisa inkumbulo yomugqa futhi kusebenza ngokushesha izikhathi ezimbalwa, ikakhulukazi ekulandeleni okude.
I-Technical Insight
Iqhinga elibalulekile ukufaka amathayela kanye ne-softmax eku-inthanethi. I-Softmax ivamise ukudinga umugqa wonke wezikolo ukuze ibale inani eliphansi, kodwa i-Flash Attention igcina isamba esiphezulu nesisebenzayo njengoba isakaza ithayela ngalinye, ikala kabusha ingxenye yangaphambili yokuphumayo ukuze umphumela wokugcina ube unembile. Ngenxa yokuthi amaphuzu amaphakathi ahlala ku-SRAM (ama-oda obukhulu ashesha kakhulu kune-HBM), i-algorithm iyazi nge-IO: inciphisa ukufundwa kwememori futhi ibhale kunemisebenzi ye-arithmetic eluhlaza.
I-Mastering Flash Attention
I-Flash Attention iyindlela ehlakaniphile yokubala isinyathelo sokunaka ngaphakathi kwe-Transformers ngaphandle kokubhala i-matrix enkulu yokunaka ukuze ubambezele inkumbulo. Kwenza amamodeli womongo omude asheshe kakhulu futhi asebenzise inkumbulo kahle ngaphandle kokushintsha izibalo zawo. I-Flash Attention iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-Flash Attention njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela oyifunayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Flash Attention alungiselela izakhiwo, idatha, nokukhetha kwengqalasizinda 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.
