Summary

Add two intra-node TLE distributed examples for reference:

  • test_tle_intra_node_allgather.py: implements all-gather by pushing local shards into peers via tle.remote.
  • test_tle_intra_node_reduce_scatter.py: implements reduce-scatter by remotely scattering rank data into
    peer buffers, then reducing locally and validating against torch.distributed.reduce_scatter_tensor.

Changes

  • Add Python examples for intra-node all-gather and reduce-scatter.
  • Add torchrun launch scripts with default FlagCX/CUDA environment variables.
  • Include correctness checks against PyTorch distributed reference outputs.
