  1. Ndechipi chinangwa chekutanga chekuburitsa optimizer nyika kuCPU kana NVMe?
    • Kuita kuti modhi iwedzere kurongeka
    • Kuderedza huwandu hwenguva dzekudzidziswa dzinodiwa
    • Kubvisa kudiwa kwema gradients zvachose
    • Kuti ikwane mamodheru makuru nekusunungura kushomeka kweGPU ndangariro
  2. For an Adam setup with two FP32 moments and an FP32 master weight, how much memory do those three values use per parameter?
    • Two bytes for all three values
    • Twelve bytes, excluding model weights and gradients
    • Sixteen bytes for the three values alone
    • Zero bytes because they are implicit
  3. Ndeipi dhizaini inoratidza yakakurumbira yakakura-chiyero optimizer kurodha?
    • A new activation function
    • JPEG mufananidzo compression
    • DeepSpeed ZeRO-Offload uye ZeRO-Infinity
    • Gradient clipping
  4. Ndeupi mutengo mukuru wekuita kuburitsa kuCPU kana NVMe?
    • Dhata inofanira kufamba pamusoro pezvishoma zvinongedzo sePCIe kana kudhisiki, ichiwedzera latency
    • Iyo modhi inokanganwa kudzidziswa kwekutanga
    • Iyo optimizer inova yemasvomhu isiriyo
    • GPU tembiricha inodonha zvakanyanya
  5. Masisitimu ekurodha anoviga sei yakawanda yekutamisa latency?
    • Nekusvetuka pfuura yekumashure
    • Nekupindirana kwedata prefetching neinoenderera mberi GPU computation
    • Nokudzidzisa parameter imwe chete panguva
    • Nekudzima kusarongeka kwakasanganiswa
  6. MuZeRO-Offload, nhanho yeAdhama optimizer inowanzoitwa kupi?
    • Zvakakwana paNVMe controller
    • Pane imwe ratidziro GPU
    • PaCPU, uchishandisa uremu hwatenzi uye nguva dzakachengetwa ipapo
    • Mukati me network switch
  7. Optimizer states are offloaded, but GPU weights and activations still exceed capacity. What follows?
    • The job can still run out of GPU memory
    • Offloading guarantees the job fits any GPU
    • The optimizer moments automatically become model activations
    • The model no longer needs forward tensors
  8. A CPU-offloaded optimizer becomes the training bottleneck. Which measurement is most relevant?
    • Only the inference accuracy
    • The UI font used for training logs
    • Only the number of dataset classes
    • Host optimizer-update time and host-device transfer time
