DrJAX is a library designed to embed a MapReduce programming model into JAX. DrJAX has multiple objectives.

1. Create a simple JAX-based authoring surface for MapReduce computations.
2. Leverage JAX's sharding mechanisms to enable highly optimized execution of MapReduce computations, especially in large-scale datacenter settings.
3. Full differentiability of DrJAX computations, including differentiating through communication primitives like broadcasts and reductions.

DrJAX is designed to make it easy to author and execute parallel computations in the datacenter. DrJAX is tailored towards large-scale parallel and distributed computations, including computations involving larger models, and ensuring that they can be run efficiently. DrJAX embeds primitives like those defined by TensorFlow Federated using the mapping capabilities and primitive extensions of JAX.
