PROFILE
Mathias Wagner
Worked on modernizing and stabilizing the CI/CD infrastructure for the lattice/quda repository, focusing on build automation and configuration using Shell and YAML. Over three months, delivered upgrades to the CUDA toolchain and GCC, standardized CI runners on Ubuntu 24.04, and introduced a new cudaclang workflow to improve reliability and reproducibility. Addressed CI build flakiness by updating caching strategies and fixing integration issues between CUDA and CMake. Enhanced the CI build matrix to support LLVM 19, automating installation scripts to ensure forward compatibility. These efforts reduced build failures, improved developer velocity, and positioned the project for future toolchain upgrades.

May 1, 2025May 2025 — Focused on CI modernization to align lattice/quda with newer compiler toolchains. Updated the GitHub Actions CI build matrix to LLVM 19 (clang++-19) and added an automated LLVM 19 installation script to ensure consistent, forward-looking builds. The change is captured in commit 48e3d631d931398468d75a37d4ad76ff0dd74a30 (Update cudaclang_githubactions_build.yml). No major bug fixes were identified this month. Impact: reduces build break risk, speeds up PR validation, and positions CI for upcoming CUDA/C++ toolchain upgrades. Skills: CI automation, LLVM toolchain management, scripting, and GitHub Actions workflow maintenance.
