Overview
Matekiniki ekuchengetedza modhi yekudzidzira mamiriro muzvidimbu (shards) kuitira kuti mahombe mamodheru agone kuchengetwa uye kurodhazve pasina kukachidzwa mundangariro kana dhisiki miganho, uye saka kumhanya kwakadonha kunogona kutora chaiko kwayakasiira. Yakakosha kune chero basa rekudzidzisa rinomhanya kwemazuva kana mavhiki kuyambuka mazhinji maGPU.
Checkpoint Sharding uye Resumable Training inyanzvi yekuvaka inobata mhando yemhando, mutengo wezvivakwa, latency, uye kuvimbika pachiyero.
Deep Dive
Nzvimbo yekudzidzira ipikicha yezvese zvinodiwa kuti utangezve: uremu hwemhando, optimizer nyika, chirongwa-chiyero chekudzidza, chinzvimbo chemutakuri wedata, uye mhodzi dzejenareta nhamba. Kune mahombe mamodheru iyi snapshot inogona kuva mazana emagigabytes, yakakura kwazvo kufaira rimwe chete kana ndangariro yemuchina mumwe chete. Checkpoint sharding inopatsanura iyo snapshot mumafaira akawanda uye akawanda mazinga, saka imwe neimwe GPU inonyora chete chidimbu chayo chakafanana. Kudzidzirazve kudzidziswa kunozorodhazve iwo shards uye kudzoreredza iyo yakazara nyika nemazvo. Pasina iyo, kumhanya kwemavhiki mazhinji kunopunzika paawa 200 kwaizofanira kutangazve kubva pakutanga. Maframeworks sePyTorch Distributed Checkpoint, DeepSpeed, uye Hugging Face Hub's sharded safetensors fomati inoita iyi tsika.
Technical Insight
Sharding inoshanda nekuti yakagoverwa kudzidziswa yatove zvikamu zvehuremu uye optimizer nyika munzvimbo dzese (kuburikidza nedata, tensor, kana ZeRO parallelism). Chiyero chega chega chinoteedzera chikamu chayo chete, kazhinji kune mafomati senge ekuchengetedza anobvumira simbe, ndangariro-mamepu kurodha. Indekisi faira inomepu mazita eparameter kune shard mafaera. Kuti utangezve deterministically, sisitimu zvakare inorambira RNG nyika, iyo optimizer nhanho kuverenga, uye chaiyo dataloader offset, saka rerun inoburitsa yakafanana kutevedzana kwemabhechi.
