Distributed Training — Google Cloud ML Engineer Practice Questions
Distributed training splits the work of training a large model across multiple machines or devices to reduce wall-clock training time and handle datasets or models that exceed single-node memory. The ML Engineer exam covers both data parallelism, where each worker processes a different mini-batch, and model parallelism, where the model itself is partitioned across devices. On Google Cloud, distributed training is commonly configured through Vertex AI custom training jobs using TensorFlow's MirroredStrategy or PyTorch's DistributedDataParallel. Choosing the right distribution strategy based on model size, hardware configuration, and convergence behavior is a practical skill the exam tests.
