e.g. fixed #1234, closed #1234, resolved #1234

📝 What does this PR do?

  1. Implements Ring Attention from https://arxiv.org/abs/2310.01889 and supports Llama. Adopts the zigzag batch splitting scheme for load-balancing (see illustration below).
image
  1. Supports both batched sequences and packed sequences.
  2. Use two streams in forward pass to overlap the low-occupancy output correction with next step's flash attn kernel. Carefully optimizes buffers to minimize memory pressure. Provides a experimental Triton kernel for output correction
  3. Save comm & compute by replacing the gather sequence op in cross entropy wtih reducing loss.
  4. Enable TP + SP in plugin and update corresponding llama and command policies.

!Future work

  1. For easy compatibility with other SP and HF interfaces, in the packed sequence mode we do not flatten the batch dim but recreates a new tensor with shape (bs, max_seqlen // sp_size). To eliminate this overhead, we can adapt each model's forward to accept flattened inputs.
  2. Pad each seq to be divisible by sp_size.
  3. Place the grad checkpoints between attn and FFN so that we only recompute FFN, not ring attention (see https://github.com/RulinShao/LightSeq/blob/8f486dad3d0670057dfbe3b30c003080b61c5325/lightseq/lightseq_ckpt_monkey_patch.py#L499)
