Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Waa maxay cilad-xumada ugu weyn ee FlashAttention bartilmaameedyada dareenka caadiga ah?
    • Akhrinta iyo qorista matrixka dareenka weyn si loo yareeyo xusuusta GPU-da
    • Tirada isku dhufashada-dhibcaha sabbaynaya
    • Qiimaha calaamadaynta qoraalka gelinta
    • Latency network u dhexeeya GPU-yada
  2. Sidee wax-soo-saarka FlashAttention barbardhigaan dareenka caadiga ah?
    • Waa qiyaas ka beddelashada saxnaanta xawaaraha
    • Waa isku mid xisaab ahaan (sax)
    • Waxay u shaqeysaa oo keliya taxane gaaban
    • Waxay beddeshaa miisaanka modelka
  3. Waa kuwee xusuusta GPU-da ay FlashAttention ka faa'iidaysato iyada oo ku hawlanaysa xogta taayirada?
    • Xusuusta weyn laakiin gaabis sare leh (HBM)
    • RAM ee CPU
    • SRAM yar laakiin aad u dheereeya
    • Kaydinta diskka
  4. Farsamo noocee ah u ogolaanaya FlashAttention xisaabinta softmax iyada oo aan la arkin dhammaan buundooyinka hal mar?
    • Ka boodista softmax gabi ahaanba
    • Isku soo wada duuboo dhammaan buundooyinka eber
    • Kahor xisaabinta softmax ee CPU
    • Online (kordhin) softmax oo leh dib-u-cusbooneysiin orod ah
  5. Sababtoo ah matrixka dareenka buuxa waligiis laguma kaydiyo HBM, isticmaalka xusuusta ayaa qiyaas ahaan:
    • Si toos ah oo leh dherer isku xiga
    • Afar ahaan dhererka isku xigxiga leh
    • Si weyn oo leh dherer isku xigxig leh
    • Si madaxbanaan oo dhererka isku xigxiga ah
  6. Which numeric format does FlashAttention-3 use in its Hopper-focused experiments to accelerate attention?
    • Only 64-bit floating point
    • FP8, with techniques to manage its numerical error
    • Integer text tokens
    • No reduced-precision format
  7. What work-partitioning change does FlashAttention-2 introduce to improve GPU parallelism?
    • It stores the complete attention matrix in HBM
    • It replaces attention with convolution
    • It reduces non-matrix-multiplication work and improves parallelization across thread blocks and warps
    • It uses only CPU execution
  8. In FlashAttention-3, what lets data movement overlap with computation?
    • Replacing attention with a lookup table
    • Computing all scores in host memory
    • Disabling the softmax step
    • Asynchronous execution on Hopper hardware
