Description
1、采样是在训练时进行的吗，对比提前采样这样的好处是什么
2、在性能测试中，5台机器一共480个物理核，然而一个tf worker需要16个核，600个worker是如何分配资源的
谢谢！

Research direction
Review the performance-test context referenced in the issue: five machines, 480 physical cores, 16 cores per TensorFlow worker, and 600 workers. Determine whether sampling occurs during training and compare it with pre-sampling, then explain how the workers are allocated. Done means documenting clear answers to both questions.
