Uhlolojikelele
Iqhinga lokulondoloza inkumbulo elimisa ukugcinwa kwamabhuku okusindayo kokuqeqeshwa (izimo ze-optimizer, ama-gradient, kwesinye isikhathi izisindo) ku-CPU RAM noma kuma-NVMe SSD esikhundleni sememori ye-GPU eyindlala. Ivumela abantu ukuba baqeqeshe amamodeli amakhudlwana kunenkumbulo ye-GPU yabo.
I-Optimizer State Offloading ku-CPU ne-NVMe iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini.
I-Deep Dive
Uma uqeqesha inethiwekhi ye-neural ngesithuthukisi esifana no-Adam, yonke ipharamitha ithwala umthwalo owengeziwe: izibalo ezimbili ezisebenzayo (umfutho nokuhluka), kanye nekhophi enembayo yesisindo, kanye negradient yayo. Ekuqeqesheni okunembayo okuxubile lokhu kungahlanganisa cishe amabhayithi angu-16 ngepharamitha ngayinye, kufiphaze amabhayithi angu-2 ngesisindo ngokwaso. Ukulayisha kususa lowo mthwalo ku-GPU. I-CPU ikhipha i-stream optimizer ingena ohlelweni olujwayelekile lwe-RAM phezu kwebhasi le-PCIe, kuyilapho ukulayishwa kwe-NVMe kuwaphusha kuze kube phansi kumadiski e-solid-state asheshayo. Idume ngabakwa-DeepSpeed's ZeRO-Infinity kanye ne-ZeRO-Offload, le ndlela ihweba ngesivinini esingahluziwe ukuze ibe namandla, ivumela i-GPU eyodwa noma amamodeli amancane eqoqo acule kahle anezigidigidi zamapharamitha.
I-Technical Insight
Ukhiye oweqa ukunyakaza kwedatha nokubala. Izifunda ze-Optimizer zihlala ku-CPU/NVMe; ngesikhathi sokubuyela emuva, ama-partitions alandwa kuqala nge-PCIe ngaphambi nje kokuba adingeke futhi isinyathelo sokulungisa sona sivame ukusebenza ku-CPU. I-ZeRO-Offload igcina izisindo eziyinhloko ze-float32 kanye nezikhathi zika-Adam ku-CPU, ngakho izibalo eziya phambili neziya emuva kuphela ezihlala ku-GPU. I-NVMe yengeza inqolobane enezigaba ukuze isikali se-terabyte sichitheke kudiski kuyilapho izingxenye ezishisayo zihlala ku-RAM.
I-Mastering Optimizer State Offloading ku-CPU ne-NVMe

Ivumela abantu ukuba baqeqeshe amamodeli amakhudlwana kunenkumbulo ye-GPU yabo. I-Optimizer State Offloading ku-CPU ne-NVMe iyibhulokhi yokwakha yobuchwepheshe ethinta ikhwalithi yemodeli, izindleko zengqalasizinda, ukubambezeleka, nokuthembeka esikalini. Ukuze wakhe ukuqonda okujulile, phatha i-Optimizer State Offloading ku-CPU ne-NVMe 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-Optimizer State Offloading ku-CPU ne-NVMe 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.
