# 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

- [x] Forward passes

- [x] Backward passes with activation reconstruction

- [x] Run optimizer

- [x] Logging

- [x] Checkpointing

- [x] Actually do pipelining

- [x] fp16 with static loss scaling

- [x] 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?
