This PR includes three related improvements:

  • Reduce communication overhead in several training and model execution paths to improve runtime efficiency.
  • Fix NPU compatibility issues in core ops and optimizer logic to improve functional correctness on NPU.
  • Add CPU core binding support and integrate it into training startup for more stable system performance.
