PROFILE
Andrew M. Bradley
Over three months, Andrew Bradley enhanced the E3SM-Project/E3SM repository by enabling PIOLibrary and CUDA support on Perlmutter, updating build configurations and environment documentation to improve GPU utilization and reliability. He addressed CUDA memory allocation stability by disabling asynchronous malloc in Kokkos, and maintained CUDA/Kokkos compatibility for Hommexx by replacing a deprecated function with a hardcoded value, ensuring stable builds across Kokkos releases. Additionally, Andrew improved the robustness of the nlmaps_check.py script using Python, refining error detection to reduce false alarms in simulation validation. His work demonstrated depth in C++, CUDA, build systems, and debugging complex workflows.

Mar 1, 2025In March 2025, delivered a targeted robustness improvement for the E3SM coupler by refining nlmaps_check.py error detection to filter area-consistency noise and prevent POSTRUN_SCRIPT failures. This fix reduces false alarms in the validation pipeline, stabilizing end-to-end runs and improving overall reliability of simulations that depend on NL map area consistency.

Feb 1, 2025Concise monthly summary for 2025-02 focusing on code maintenance and compatibility improvements in the E3SM project. Key activities centered on ensuring CUDA/Kokkos compatibility for Hommexx by replacing a deprecated Kokkos function with a hardcoded value to preserve functionality across newer Kokkos releases. The change reduces risk of breakages during upstream updates while maintaining expected behavior and performance characteristics. The work supports stable builds and smoother upgrade paths for users relying on CUDA backend.
