Why coordinate resource admission for a fixed-size distributed training worker group?

预览每个问题8 问题

当您参加测验时，就会出现答案和解释。

  1. Why coordinate resource admission for a fixed-size distributed training worker group?
    • To guarantee every process starts at exactly the same nanosecond
    • To guarantee the model converges
    • To remove all worker communication
    • To reduce partial-start situations where workers wait for unavailable peers
  2. How does Kubernetes normally express a device-plugin GPU resource request?
    • As arbitrary fractions of CPU clock cycles
    • As an integer count of advertised device resources
    • As a DNS hostname only
    • As a string of model output tokens
  3. 拓扑感知调度试图优化什么？
    • 尽可能分散工作岗位
    • 最大限度地减少用户数量
    • 将通信等级置于 NVLink 等快速互连上
    • 选择最便宜的电力供应商
  4. 哪个附加组件通常与 Kubernetes 一起用于 AI 作业的批量和组调度？
    • 火山
    • 阿帕奇·卡夫卡
    • 雷迪斯
    • 格拉法纳
  5. What must a training application provide if a preempted job should resume its previous progress?
    • A guarantee that preemption saves optimizer state automatically
    • A usable checkpoint and recovery procedure
    • A renamed pod with no saved state
    • A higher learning rate for its first resumed step
  6. 共享集群中公平份额配额的作用是什么？
    • 确保一支球队永远获胜
    • 禁用调度程序
    • 防止任何一个团队垄断所有 GPU
    • 加快单个作业的速度
  7. A fixed worker group needs eight GPU resources but only four are available. What can group admission accomplish?
    • Keep the group pending until its configured minimum requirements can be met
    • Invent the missing four GPU devices
    • Turn every worker into a CPU process without configuration
    • Guarantee completion even with no admitted workers
  8. Two communicating GPU jobs fit the same resource counts on different nodes. Why consider topology as well?
    • The resource count alone fixes every transfer latency
    • Topology determines the training labels
    • Only node names affect all-reduce outputs
    • Interconnect placement affects communication costs between their workers
