Month: 2025-12 — Focused on ensuring gyrokinetic model correctness and reducing configuration risks. Key deliverable: documentation and header updates to enforce that scale_factor is nonzero (>0) to avoid inadvertently disabling collisionless terms in the gyrokinetic model. This work tightens the feedback loop between configuration and physics, and reduces likelihood of silent misconfigurations impacting simulations.

September 2025: Implemented a resilience improvement for EQDSK file parsing in the ammarhakim/gkylzero repository by adding a warning when EQDSK headers are missing. This prevents silent misparsing, improves data integrity, and reduces downstream debugging effort when ingesting legacy or headerless EQDSK files.

May 2025 monthly summary for ammarhakim/gkeyll: Focused on stabilizing GPU compute environments for gkylzero by enforcing CUDA version compatibility and standardizing module loads (CUDA, OpenMPI, NCCL) across machine configuration files. This work reduces runtime errors, improves portability across deployments, and accelerates GPU workloads. Contributed a compatibility fix documented in commit 50344dfd11ca69fb9118deaffae04528ebe7ef32.

Monthly summary for 2025-04: Delivered GPU-enabled workflow enhancements for ammarhakim/gkeyll on Snellius. Implemented CUDA environment setup, GPU job submission scripts, and build-prefix configuration to streamline CUDA-accelerated tasks. No major bugs fixed this month. Overall impact: accelerated GPU workload execution, improved deployment reproducibility, and reduced setup time, enabling scalable experiments on Snellius. Technologies/skills demonstrated: CUDA, MPI, cluster environment/modules, build configuration, and script automation.
