Pipelined Swarm Training

Swarm training "framework" using Haiku + Jax + Ray.

Designed for training large language models in a model parallel fashion with unreliable, heterogeneous nodes. (eventually)

Look in swarm_run.py for an example of running a character transformer on enwik8.

TODOs

• Forward passes
• Backward passes with activation reconstruction
• Run optimizer
• Logging
• Checkpointing
• Actually do pipelining
• fp16 with static loss scaling
• Integer quantization for activations and gradients between layers
• Get rid of pipeline stalls from running optimizer
• Data parallelism with multiple nodes per layer and gradient/weight aggregation
• Heterogeneous nodes with potentially multiple layers per node
• Handle unbalanced and unreliable nodes (layerdrop)
• Dynamic node addition
• 1T or bust?
