March 2026 monthly highlights for Trilinos and Spack packages focused on hardware portability, packaging readiness, and versioned releases for the Compadre Toolkit. Key outcomes span CUDA/HIP build improvements, new release packaging, and compatibility work to maintain backward compatibility with evolving dependencies and toolchains.

February 2026: Delivered modernization and stabilization across spack-packages and Trilinos repos. Upgraded core dependencies for modern toolchains, expanded compiler coverage (including LLVM Fortran), improved Python 3.10 compatibility, and hardened the test suite for ROCm/Kokkos interoperability. These changes enable downstream users to build with newer standards and more compilers, while improving reliability and integration of configurations and tests.

January 2026 monthly summary focusing on key accomplishments for the spack/spack-packages repository. Focused on enhancing multi-language interoperability and dependency management to improve user workflows. No major bug fixes were recorded this month.

2025-10: XYCE packaging in spack-packages gained 7.10.0 support, enabling installation via Spack. Added a new version entry and its SHA256 checksum to package.py to ensure reproducible builds and easier maintenance. This work broadens version coverage and accelerates deployment for users needing XYCE 7.10. Overall, no major bugs fixed in this period. The changes strengthen packaging reliability and pave the way for future version upgrades. Key technologies and skills demonstrated include Spack packaging, version pinning, checksum verification, and strong PR/commit discipline (e.g., commit 76919c7a4a2a40f9710a5a5ebf2ce2bb4236627c, referenced in PR #1788).

Month 2025-09 — Key feature delivered: Compadre toolkit compatibility upgrade for GMLS within the trilinos/Trilinos workflow. Upgraded the Compadre toolkit to a newer Kokkos version, standardized the Kokkos threads argument, refactored GTest handling, and refreshed documentation and examples; core GMLS functionality remained unchanged. The included automatic snapshot (commit 1338c2b409725b52c0ee840bb6dadd3920218b05) updates TRIBITS for examples to use --kokkos-num-threads. Major bugs fixed: none identified this month. Overall impact: reduces integration risk, improves cross-platform build stability and performance, and accelerates onboarding for Kokkos-driven workflows. Technologies/skills demonstrated: Kokkos, Trilinos integration, Compadre toolkit, GMLS, GTest, Tribits, documentation and testing best practices.

2025-08 monthly summary for spack-packages work focusing on Xyce upgrade and build compatibility improvements. Delivered Xyce 7.9.0 upgrade with FFTW variant and MPI/C build compatibility in spack/spack-packages, including a GCC compiler constraint to improve build reliability and ensure correct MPI handling for C builds across environments. This enhances deployment flexibility and HPC readiness. No explicit bug fixes recorded in this period; primary value came from compatibility enhancements and smoother deployments. Commit reference associated with the change: 36d8ba1dcc0a334f85fda69e8a497910f7f4d585.

July 2025 monthly summary for developer work in the spack-spack-packages repo, focused on delivering a succinct, value-driven package release update and dependency cleanup.

December 2024 performance summary for core Spack repos. Delivered cross-repo build-system hardening and dependency compatibility updates to support newer toolchains (Kokkos, CMake) and Python bindings, ensuring reliable multi-variant builds and smoother releases. Coordinated upgrades in spack-packages and spack to align compadre/py-pycompadre and xyce/pymi, with added Python-venv support and improved debugging/optimization workflows.
