You have a TensorFlow training script that runs on a single machine. To speed up training on Vertex AI with 8 GPUs on a single machine, which strategy should you use?

Trap 1: tf.distribute.ParameterServerStrategy

ParameterServerStrategy is for asynchronous distributed training with parameter servers.

Trap 2: tf.distribute.TPUStrategy

TPUStrategy is for TPU hardware, not GPUs.

Trap 3: tf.distribute.MultiWorkerMirroredStrategy

MultiWorkerMirroredStrategy is for multi-machine distributed training.
