Oct 1, 2024October 2024 (2024-10) for hugggingface/picotron focused on delivering portable, scalable benchmarking and training workflows, while hardening parallel compute paths. Key features delivered include Slurm-based benchmarking submission and portability improvements, model configuration tooling, experiment tracking, and flexible pipeline engine selection. Major bug fixes addressed correctness and stability in parallel training paths and context-parallel input handling, enabling longer sequences and safer gradient synchronization. Key features delivered: - Slurm-based benchmarking submission and portability improvements: added Slurm integration for benchmarking/workflow automation; scripts to check job statuses, create model configs, and submit jobs to Slurm; standardized naming and avoided hard-coded paths to improve portability. - Model configuration tooling: introduce create_config.py to generate model configuration files from Hugging Face AutoConfig; simplifies configuration management and exposes finer control over parallelism settings; refactors training script to properly initialize the dataloader and compute tokens per step. - Experiment tracking with Weights & Biases: integrate WandB for experiment tracking; config creation supports a use_wandb flag and training script initializes wandb logging with the experiment name as the run name for clarity. - Flexible pipeline engine selection (pp_engine): add support to switch between pipeline parallel engines ('afab' and '1f1b') via a new pp_engine parameter; refactors argument parsing and configuration to conditionally use the chosen engine. Major bugs fixed: - Pipeline parallel correctness and parameter validation: improve gradient synchronization correctness by initializing requires_grad_sync at the start of backward pass; add assertions to TensorParallel to ensure num_attention_heads and num_key_value_heads are divisible by tensor parallel world size to prevent runtime errors. - Context parallel input handling and RoPE alignment: fix input handling for context parallel; remove duplicate parallel_input usage, rename update_rope to clarify its purpose, and adjust RoPE configuration to support longer sequences. Overall impact and accomplishments: - Significantly improved portability and reproducibility of benchmarking runs on HPC clusters; reduced manual setup through Slurm tooling; stronger experiment traceability with WandB; improved stability of complex parallel configurations enabling larger-scale experiments with context and pipeline parallelism. Technologies/skills demonstrated: - Slurm-based HPC automation, Hugging Face AutoConfig tooling, Python tooling for config management, and robust training pipeline engineering (pipeline, context, and tensor parallelism). Weights & Biases integration demonstrated for reproducibility and analytics. Commit-level changes show a disciplined approach to incremental, testable improvements.
