PROFILE
Sean Baccas
Worked on the idaholab/moose repository to enhance simulation flexibility and test reliability in high-performance computing environments. Delivered user-configurable MFEM flux spaces and disabled p-refinement, updating documentation to clarify estimator behavior and streamline code maintenance. Addressed build compatibility by introducing targeted includes and implemented safeguards to prevent mesh rebalancing during p-refinement, ensuring stable numerical methods. Focused on stabilizing CUDA test runs by switching solver configurations, which reduced test flakiness and improved CI feedback cycles. Utilized C++ for algorithm design, build system management, and software testing, demonstrating a methodical approach to software engineering and maintenance in complex scientific computing workflows.

Mar 1, 2026March 2026: Delivered MFEM/MOOSE enhancements and quality improvements that increase numerical flexibility, build reliability, and maintainability. Key features delivered include user-configurable MFEM flux spaces and disabling p-refinement with updated documentation. Major bugs fixed include MFEM build compatibility for MOOSE_MFEM by adding MFEMProblem.h include and safeguards to prevent mesh rebalancing during p-refinement. Maintenance efforts included removing an unused mesh refinement unit test. Overall impact: more flexible simulations, stable builds, and a maintainable codebase. Technologies/skills demonstrated: MFEM/MOOSE integration, build-system robustness, documentation updates, and test maintenance.

Aug 1, 2025August 2025 monthly summary focusing on stabilizing CUDA test runs in idaholab/moose by switching the test configurations from MFEMHypreGMRES to MFEMHyprePCG across CUDA-related test setups, including mfem multiapps and timesteppers. Implemented as part of a targeted test infrastructure fix (commit c1ffd8f424465536f09d1287c79b2a7a3b630917). This change reduced CUDA-related instability, shortened CI feedback cycles, and improved overall reliability for CUDA-enabled test runs. Business value: more deterministic validation, faster release cycles, and stronger confidence in CUDA-related code paths. Skills demonstrated: debugging complex test configurations, CUDA/MFEM/Hypre integration, and precise Git-based change management.
