Mar 1, 2026March 2026 (2026-03) monthly summary for idaholab/moose. The month focused on strengthening test capabilities, reliability, and scalability of the TestHarness across platforms and HPC environments, while keeping maintenance and code quality at a high level. Key features delivered: - CAPABILITIES: Introduced known_capabilities to the testroot and began using them in tests; lays groundwork for a more deterministic capabilities flow. - CAPABILITIES: Collected and reused capabilities captured during tests within the TestHarness to feed test flows, improving end-to-end consistency. - TEST HARNESS: Reworked memory tracking and added CPU tracking; introduced memory/CPU kill capabilities and active-jobs tracking to improve observability and control during stress tests. - TEST HARNESS: Added min_slots options for netgen tests and used parallel/tracked execution to improve resource utilization and timing stability. - CODE HYGIENE: Typing visibility improvements, Black formatting, and cleanup (removal of legacy modules) to simplify maintenance and reduce noise in public typing. Major bugs fixed: - Fixed reporting and handling of unknown or non-existent capabilities in the test harness and capabilities flow. - Updated tests to account for unknown capabilities and adjusted --required-capabilities expectations. - Guarded against killing a job more than once and improved command invocation stability on macOS. - Improved memory reporting accuracy and memory-conversion correctness to prevent misreporting. - Hardened test harness integration with rebase conflicts and added resilience against FileNotFoundError scenarios. Overall impact and accomplishments: - Enhanced reliability and predictability of test runs, enabling safer parallelization and memory-aware scheduling across large-scale HPC environments. - Reduced flaky tests and crashes due to capability-handling issues, with cleaner, more maintainable capability logic. - Strengthened observability into memory and CPU usage, empowering data-driven resource budgeting and performance tuning. - Maintained alignment with platform updates (LibMesh submodule, PETSc, OpenMPI, and MPI base containers) to support current workloads and dependencies. Technologies/skills demonstrated: - Python-based TestHarness enhancements, memory/CPU monitoring, and resource control (kill capabilities, active jobs, min_slots). - Slurm and OpenMPI integration for memory usage tracking and topology reporting. - Code quality practices (Black formatting, typing hygiene) and dependency management (LibMesh/PETSc, etc.).
