I-BFM 166.560M replay buffer

Replay-buffer snapshot from the I-BFM H200 training run at 166,559,744 environment steps (8 ranks). This dataset accompanies the selected checkpoint in the I-BFM code release and the paper.

Files

checkpoint/buffers/train_rank_0/ through train_rank_7/ each contain buffer.hdf5 and config.json. The eight HDF5 files total 225,689,714,688 bytes. SHA256SUMS records checksums for all 16 buffer files. Preserve both files in each rank directory and the directory names when downloading.

The buffer uses the release code's TrajectoryDictBufferMultiDim HDF5 format. It is a snapshot of replay state, not a standalone training checkpoint; exact resume additionally needs the matching model and optimizer state.

Provenance

  • Checkpoint step: 166,559,744 environment steps.
  • Training: 8 H200 workers.
  • The HDF5 data was generated during the original I-BFM training run. It includes state and action trajectories, latent vectors, and auxiliary reward fields.
