Distributed Llama

Connect home devices into a powerful cluster to accelerate LLM inference. More devices mean faster performance, leveraging tensor parallelism and high-speed synchronization over Ethernet.

Supports Linux, macOS, and Windows. Optimized for ARM and x86_64 AVX2 CPUs.

🚧 Known Limitations

• You can run Distributed Llama only on 1, 2, 4... 2^n nodes.
• The maximum number of nodes is equal to the number of KV heads in the model #70.
• Only the following quantizations are supported #183:
• q40 model with q80 buffer-float-type
• f32 model with f32 buffer-float-type

The project is split up into two parts:

• 🔸 Root node - it's responsible for loading the model and weights and forward them to workers. Also, it synchronizes the state of the neural network. The root node is also a worker, it processes own slice of the neural network.
• 🔹 Worker node - it processes own slice of the neural network. It doesn't require any configuration related to the model.

You always need the root node and you can add 2^n - 1 worker nodes to speed up the inference. The RAM usage of the neural network is split up across all nodes. The root node requires a bit more RAM than worker nodes.

🎹 Commands

• dllama inference - run the inference with a simple benchmark,
• dllama chat - run the CLI chat,
• dllama worker - run the worker node,
• dllama-api - run the API server.
