March 2025 (2025-03) focused on laying the foundations for Pathways metrics collection in AI-Hypercomputer/xpk, positioning the project for improved observability and data-driven optimization. The month delivered environment-configuration groundwork across the Pathways workload to enable metrics collection in future sprints, covering worker, rm, and proxy components in workload.py. No major bug fixes were completed this period; work emphasized correctness, future compatibility, and alignment with metrics initiatives.

November 2024 performance summary: Expanded distributed initialization test coverage and stabilized test tooling across TPU platforms and CI environments. Key efforts include extending JAX distributed.initialize() tests to cover TPU v4/v5p across GCE and GKE (single-slice and multi-slice configurations with multiple test setups) and introducing a Bash-based test script for Airflow that verifies jax.distributed.initialize() with Python3 and robust exit-status reporting.
