PROFILE

Cédric Chevalier

Worked extensively on the Spack and spack-packages repositories to upgrade and maintain the Kokkos software stack, delivering new features and resolving compatibility issues across multiple versions. Focused on build system reliability, dependency management, and package synchronization, the work included updating download URLs, SHA256 checksums, and enforcing standardized build configurations using CMake and Python. Addressed integration challenges by aligning Kokkos, Kokkos Kernels, and Kokkos-FFT versions, refining test workflows, and documenting compatibility constraints such as those with PETSc. These efforts improved build reproducibility, CI stability, and future-proofed the package ecosystem for high-performance computing and CUDA-enabled environments.

Oct 1, 2025

October 2025 monthly summary for spack/spack-packages focused on delivering build reliability and governance improvements. Key efforts centered on Kokkos build configuration standardization for v4.7.00+ and updating project governance to reflect current maintainers. These changes reduce configuration drift, improve consistency across environments, and clarify ownership for ongoing maintenance, with minimal functional impact.
