Not

  1. Benchmark testlerimiz olası tüm optimizasyon birleşimlerini kapsamaz. Örneğin, varsayılan yapılandırmasında en iyi performansı gösteren çıkarım motorunu sonraki ayarlamalar için başlangıç noktası olarak seçeriz. Bu eleme yaklaşımı yerel bir optimum verir; bu, genel optimum olmayabilir.
  2. En büyük toplu iş boyutu, zamanlama yapılandırması, genişletilmiş KV önbelleği, CUDA graph, Torch Compile gibi belirli kullanım senaryolarına bağlı başka optimizasyonlar da vardır. Bu belgedeki sonuçlar, daha hedefli optimizasyonlar için başlangıç noktası olabilir.
  3. Testler belirli donanım ve yazılım yapılandırmalarında yürütülmüştür. Çıkarım motorlarındaki gelişmeler sonuçları değiştirebilir.
  4. Nicemleme doğruluğu etkileyebilir; ancak FP8 nicemleme çoğu modelde %1'den az doğruluk kaybı sağlayabilir. Ayrıntılar için değerlendirme sonuçlarına bakın. Bu nedenle yüksek işlem hacimli sunum senaryolarında FP8 nicemleme önemle önerilir.

Eksik noktalar veya yeni değişiklikleri yansıtacak güncellemeler varsa bize bildirin.

Optimizasyon hedefi

Yüksek eş zamanlı isteklerde yüksek işlem hacmi sağlar.
