Overview
Chirevo chekuchengetedza ndangariro chinomisa kuchengetwa kwebhuku kunorema kwekudzidziswa (optimizer states, gradients, dzimwe nguva uremu) muCPU RAM kana paNVMe SSDs pane kushomeka GPU memory. Inoita kuti vanhu vadzidzise mamodheru akakurisa kupfuura ndangariro dzeGPU yavo yaizobvumira.
Optimizer State Offloading kuCPU neNVMe inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero.
Deep Dive
Paunodzidzisa neural network ine optimizer senge Adamu, imwe neimwe parameter inotakura mukwende wakawedzerwa: maviri anomhanya manhamba (kumhanya uye musiyano), pamwe neiyo yakazara-chaiyo kopi yehuremu, pamwe negradient yayo. Mukudzidziswa kwakasanganiswa-chaizvo izvi zvinogona kuita zvinosvika gumi nematanhatu mabhayiti paparamita, kudikitira mabhayiti maviri ehuremu hwacho. Kuburitsa kutakura mutoro iwoyo kubva paGPU. CPU inoburitsa hova optimizer inopinda mune yakajairwa system RAM pamusoro pePCIe bhazi, ukuwo NVMe kuburitsa ichivasundidzira nzira yese kudzika kukurumidza solid-state disks. Yakasimudzirwa neDeepSpeed's ZeRO-Infinity uye ZeRO-Offload, nzira iyi inotengeserana nekumhanya kwehuwandu, ichirega imwe GPU kana diki diki-tune modhi ine mabhiriyoni emaparamita.
Technical Insight
Chinokosha ndechekupindirana kwekufamba kwedata nekombuta. Optimizer inoti inogara muCPU/NVMe; panguva yekudzokera kumashure, zvikamu zvinofanotorwa pamusoro pePCIe nguva isati yadiwa uye iyo optimizer nhanho pachayo inowanzo mhanya paCPU. ZeRO-Offload inochengeta float32 master huremu uye Adam nguva paCPU, saka yekumberi nekumashure chete math inogara paGPU. NVMe inowedzera tiered cache kuitira kuti terabyte-scale inoti iparare kune diski nepo zvikamu zvinopisa zvichigara muRAM.
Mastering Optimizer State Offloading kuCPU uye NVMe
Chirevo chekuchengetedza ndangariro chinomisa kuchengetwa kwebhuku kunorema kwekudzidziswa (optimizer states, gradients, dzimwe nguva uremu) muCPU RAM kana paNVMe SSDs pane kushomeka GPU memory. Inoita kuti vanhu vadzidzise mamodheru akakurisa kupfuura ndangariro dzeGPU yavo yaizobvumira. Optimizer State Offloading kuCPU neNVMe inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero. Kuti uvake kunzwisisa kwakadzama, bata Optimizer State Offloading kuCPU neNVMe semuenzaniso wekushandisa, kwete chinhu chimwe chete: tsanangura zvaunoda mhedzisiro, kujekesa fungidziro, uye patsanura izvo zvingaitwe nehurongwa nekuvimbika kubva kune zvichiri kuda kutonga kwenyanzvi.
Mukuita, zvikwata zvakasimba zvinoshandisa Optimizer State Offloading kuCPU uye NVMe inokwidziridza zvivakwa, data, uye sarudzo dzezvivakwa zvinopesana nekuvimbika uye mutengo. Ivo vanonyora zvakajeka maitiro ebudiriro, bvunzo vachipokana ne data rechokwadi uye mafambiro ebasa, uye iterate zvichibva pane zvakacherechedzwa maitiro ekutadza kwete kuhwina-nguva imwe chete yebhenji. Apa ndipo apo kunzwisisa kwe theoretical kunoshanduka kuve kugona kwakasimba pane chigadzirwa, mutemo, uye mashandiro.
Zvisarudzo zvezvivakwa zvinotyaira kuita uye mutengo wekushandisa kwemakore. Panguva imwecheteyo, Kukwirisa imwe bhenji kunogona kuvanza yakafara system kushaya simba. Nzira yakatsiga ndeyekubatanidza kukurumidza kuyedza nekutonga: mhanyisa vatyairi vendege, tora humbowo, buritsa matanda esarudzo, uye urambe uchivandudza chengetedzo semaitiro emuenzaniso, zvinotarisirwa nemushandisi, uye zvinodikanwa zvekutonga.
