For 2025-12, NVIDIA/NeMo-Skills focused on porting the ICPC evaluation framework to the IOI framework, with enhanced input case handling and metrics processing. This work improves evaluation fidelity and portability, enabling consistent IOI-style benchmarking and reducing future rework. No major bugs fixed this period; the team concentrated on delivering a framework-compatible evaluation path and solidifying the testing harness. The port is tracked under commit 9985b2e8446654d78377b01db7844650fe337c4d ("Port ICPC changes to IOI (#1046)").

November 2025 — NVIDIA/NeMo-Skills: Focused on strengthening sandbox reliability and error resilience. Implemented robust HTTP error handling in the sandbox readiness check to prevent crashes when external services fail. This work reduces downtime risk and improves user experience for sandbox initialization.

October 2025 monthly summary for Kipok/NeMo-Skills. Delivered IOI Benchmark Enhancements and Documentation, improving evaluation accuracy, reliability, and developer productivity. Implemented interleaving support and refactored the IOI evaluator to a class-based design. Improved sandbox environment variable handling for configurable evaluation, updated docs for data preparation and usage, and added an IOI test on the Hieroglyphs dataset to validate the evaluation pipeline. These changes reduce onboarding time, support more flexible experiments, and enhance test coverage.

Monthly Summary for 2025-08 (Kipok/NeMo-Skills): Key features delivered: - Sandbox Overlap Flexibility in Task Scheduling: extended sandbox execution to allow overlapping sandboxes when with_sandbox is true or server_config is present, increasing pipeline flexibility and throughput. (Commit: 9ea9677e532fe277fafcc6474e4ce151091ac10e) - IOI Benchmark Support and Evaluator Integration: added IOI dataset support for evaluation, including dataset preparation files and integration of the IOI evaluator into the evaluation framework; minor sandbox refactor to enable support for new languages like 'shell'. (Commit: b3a9981b2aac399835356ac3a6149c03f93be548) Major bugs fixed: - No major bugs reported this month. Focus remained on feature delivery and refactoring to support IOI and new language capabilities. Overall impact and accomplishments: - Improved pipeline throughput and flexibility through overlapping sandboxes. - Expanded evaluation coverage with IOI benchmark support, accelerating experiments and benchmarking readiness. - Broadened language support (including shell) and strengthened sandbox infrastructure for future features. - Codebase moved closer to IOI benchmarking readiness, with end-to-end readiness from data prep to evaluation. Technologies/skills demonstrated: - Python-based sandbox orchestration and scheduling logic - Evaluation framework integration and IOI evaluator - Dataset preparation tooling and sandbox refactoring for language support - Commit-driven development and cross-team collaboration (refs: 9ea9677e532fe277fafcc6474e4ce151091ac10e; b3a9981b2aac399835356ac3a6149c03f93be548)

March 2025 — Kipok/NeMo-Skills: Stabilized SFT training workflow by fixing checkpoint averaging logic to robustly handle average_steps, including comma-separated values and the 'all' keyword. The fix improves reliability and reproducibility of checkpoints during supervised fine-tuning, enabling smoother automation and faster iteration over model improvements.
