In TensorFlow 2, parameter server training is powered by the tf.distribute.experimental.ParameterServerStrategy class, which distributes the training steps to a cluster that scales up to thousands of workers (accompanied by parameter servers). Supported training methods There are two main supported training methods:

It is not entirely clear how parameter servers know what to do in distributed training with tensor flow. For example, in this SO> question , the following code is used to configure parameter server tasks and work tasks: if FLAGS.job_name == "ps": server.join() elif FLAGS.job_name == "worker": ##some training code. How does it server.join()indicate that this task should be a …

In TensorFlow 2, parameter server training uses a central coordinator-based architecture via the tf.distribute.experimental.coordinator.ClusterCoordinator class. In this implementation, the worker and parameter server tasks run tf.distribute.Server s that listen for tasks from the coordinator.

In TensorFlow 2, we recommend a central coordiantion-based architecture for parameter server training, where workers and parameter servers run a tf.distribute.Server and there is another task that creates resources on workers and parameter servers, dispatches functions, and coordinates the training. We refer to this task as “coordinator”. The coordinator uses a

TL;DR: TensorFlow doesn't know anything about "parameter servers", but instead it supports running graphs across multiple devices in different processes. Some of these processes have devices whose names start with "/job:ps", and these hold the variables. The workers drive the training process, and when they run the train_op

Data Parallelism in TensorFlow In TensorFlow 2.x, distributed training (scoring and evaluation) can be accomplished by simply running existing code within the scope of a so-called DistributionStrategy. TensorFlow 2.x is strategy-aware, and therefore recognizes when run in the context of a DistributionStrategy.

Frequently Asked Questions

What is parameter server in TensorFlow 2??

In TensorFlow 2, parameter server training uses a central coordinator-based architecture via the tf.distribute.experimental.coordinator.ClusterCoordinator class. In this implementation, the worker and parameter server tasks run tf.distribute.Server s that listen for tasks from the coordinator.

What do TensorFlow tasks need to know??

The coordinator task needs to know the addresses and ports of all other TensorFlow servers except the evaluator. The workers and parameter servers need to know which port they need to listen to. For the sake of simplicity, you can usually pass in the complete cluster information when creating TensorFlow servers on these tasks.

What is asynchronous training in TensorFlow??

This is why sometimes parameter server-style training is called asynchronous training. In TensorFlow 2, parameter server training is powered by the tf.distribute.experimental.ParameterServerStrategy class, which distributes the training steps to a cluster that scales up to thousands of workers (accompanied by parameter servers).

Is it possible to use synchronous parameter server training in TensorFlow??

Synchronous parameter server training is not supported. It is usually necessary to pack multiple steps into a single function to achieve optimal performance. It is not supported to load a saved_model via tf.saved_model.load containing sharded variables. Note loading such a saved_model using TensorFlow Serving is expected to work.
