Uhlolojikelele
I-PagedAttention iyindlela yokuphatha inkumbulo egcina inqolobane yokunaka yemodeli yolimi kumabhulokhi amancane asebenziseka kabusha esikhundleni sesiqephu esisodwa esikhulu esihlangene. Inika amandla i-vLLM, injini enikeza umthombo ovulekile ekhuphula ngokuphawulekayo ukuthi zingaki izicelo i-GPU eyodwa engakwazi ukuzisingatha.
I-PagedAttention ne-vLLM iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Uma imodeli yolimi ikhiqiza umbhalo, igcina 'inqolobane ye-KV' (amavekhtha angukhiye kanye nenani) kuwo wonke amathokheni ayibonile ukuze ithokheni elandelayo ihambisane nengqikithi egcwele. Ngokwesiko isicelo ngasinye besigodla i-slab eyodwa enkulu yememori ye-GPU enosayizi wobude bayo obukhulu obungaba khona, simosha amanani amakhulu lapho ukulandelana kukufushane noma kuhluka ngobude. I-PagedAttention, eyethulwe ephepheni le-vLLM lango-2023 elivela e-UC Berkeley, iboleka umqondo wokuphethwa kwememori ebonakalayo ezinhlelweni zokusebenza: ihlukanisa inqolobane ye-KV ibe amabhulokhi anosayizi ongashintshi ongaphila noma kuphi enkumbulo futhi anikezwe ngokufunwa. Ithebula lokubheka libonisa ukuma kwamathokheni okunengqondo kumabhulokhi abonakalayo. Lokhu kucishe kuqede ukuhlukana kwenkumbulo futhi kuvumela amabhulokhi ukuthi abelwane, isibonelo kuyo yonke imiphumela eminingi evela ekwazisweni okufanayo.
I-Technical Insight
Inqolobane ye-KV ihlukaniswa ibe amakhasi anosayizi ongashintshi, ngalinye liphethe okhiye namanani enombolo emisiwe yamathokheni. Ithebula lebhulokhi elilandelanayo libonisa izindawo ezinengqondo ezindaweni zekhasi, ngakho-ke inqolobane yokulandelana akufanele ihlangane. Ngenxa yokuthi iziqalo ezifanayo (ukwaziswa kwesistimu okwabelwana ngayo, noma amagatsha okusesha i-beam) zingakhomba amakhasi abonakalayo afanayo ngokukopisha-phezu kokubhala, inkumbulo iphinda isetshenziswe esikhundleni sokuphindaphinda, ukusika imfucuza isuka ngaphezu kuka-60% iye kumaphesenti ambalwa.
I-Mastering PagedAttention kanye ne-vLLM
I-PagedAttention iyindlela yokuphatha inkumbulo egcina inqolobane yokunaka yemodeli yolimi kumabhulokhi amancane asebenziseka kabusha esikhundleni sesiqephu esisodwa esikhulu esihlangene. Inika amandla i-vLLM, injini enikeza umthombo ovulekile ekhuphula ngokuphawulekayo ukuthi zingaki izicelo i-GPU eyodwa engakwazi ukuzisingatha. I-PagedAttention ne-vLLM iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-PagedAttention ne-vLLM 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-PagedAttention ne-vLLM athuthukisa 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.
