Chihta-wang
Worked extensively on the exasim-project/NeoFOAM repository, delivering robust CI/CD infrastructure, GPU benchmarking, and mesh generation utilities. Focused on automating performance evaluation across NVIDIA, AMD, and Intel GPUs, the work included cross-platform CI scripting, Docker-based environment configuration, and CMake build system enhancements. Implemented 1D uniform mesh generation and comprehensive unit tests to ensure geometric correctness, while also addressing critical bugs in mesh alignment and CI gating logic. Enhanced developer onboarding and documentation, streamlined PR workflows, and integrated profiling tools using C++ and Bash. The approach emphasized reliability, maintainability, and observability, resulting in faster validation and improved developer productivity.

Jan 1, 2026January 2026 focused on making NeoFOAM CI more reliable, scalable, and hardware-aware. We delivered cross-GPU CI support beyond NVIDIA H100, enabling use of NVIDIA, AMD, and Intel GPUs in GitHub and GitLab workflows, with precise skip controls to optimize compute and speed up validation across diverse hardware. The CI pipeline was restructured for clarity and reliability, consolidating before_script blocks, clarifying execution flow, and integrating explicit GPU-skipping rules with testing/benchmarking. Environment readiness improvements were implemented, including separation of OpenFOAM setup by hardware vendor, cleanup of AMD-specific environment variables, and adding a Python path configuration for the Intel Docker image. Collectively, these changes increased test coverage across multiple hardware configurations, reduced CI flakiness, and accelerated validation of performance-critical code paths.
