December 2025 (2025-12) monthly summary for trilinos/Trilinos. The primary effort this month focused on modernizing the STK Mesh Library by updating deprecated DualView usage to align with current code standards. This compatibility work reduces technical debt, minimizes risk from deprecated APIs, and enhances build stability across the latest codebase. While no new user-facing features were introduced, the change improves maintainability and performance characteristics through cleaner DualView usage and updated code paths.

November 2025: Implemented Kokkos 5.0 compatibility and new View integration across Trilinos core packages, with namespace and API alignments to support Kokkos 5.0 and legacy View paths. Updated ArithTraits usage across kokkos >= 4.7.99 and 5.0, aligned create_staticcrsgraph, and fixed Sacado view usage. Gated FadMPAssembly perf tests to preserve legacy View compatibility while enabling the new View path. This work enhances upgrade safety, cross-package stability, and portability for downstream users.

October 2025 monthly summary for Trilinos (repo trilinos/Trilinos). Focused on delivering key features, fixing critical issues, and improving maintainability to support future Kokkos/KokkosKernels developments. Highlights include namespace compatibility work for ArithTraits across multiple packages, code quality improvements, and packaging cleanups that reduce downstream risks. The work aligns with business goals of stable builds, smoother integration for downstream projects, and readiness for the Kokkos 5.0 development cycle.

Monthly summary for 2025-09: Delivered targeted dependency upgrade and alignment in spack-packages. Upgraded Kokkos to 4.7.01 (including kernels and nvcc wrapper), added CUDA 13 incompatibility warning for pre-4.7.01 Kokkos, and aligned Trilinos to depend on Kokkos 4.7.01 on master to ensure consistent dependency resolution. These changes reduce build failures, improve downstream upgrade paths, and enhance CUDA tooling compatibility. No separate bug fixes were recorded this month; the primary impact was stabilization of core dependencies and forward-compatibility for CUDA toolchains.

August 2025 monthly summary for trilinos/Trilinos: Delivered stabilization, modernization, and build reliability improvements across core components, with concrete baselines, API alignment, and compiler/toolchain fixes that reduce integration risk and enable faster feature delivery. The work focused on reproducible baselines, cross-package API consistency, and modernization efforts that directly improve developer productivity and long-term maintainability.

Month: 2025-07 — Focused on enabling a robust Kokkos upgrade and stabilizing Trilinos builds against Kokkos 4.6.02. Delivered cross-compiler compatibility improvements (SYCL pointer fixes, warnings, and constexpr refinements), expanded test coverage, and release documentation to support downstream adoption.

June 2025 (2025-06) monthly summary for trilinos/Trilinos. Key feature delivered: Kokkos 4.x compatibility – updated partition_space to accept a vector of weights to align with the newer Kokkos API; changes implemented in Ifpack2_BlockTriDiContainer_impl.hpp and the Phalanx library to ensure correct execution-space partitioning under Kokkos 4.x. Major bugs fixed: none reported this month. Overall impact: restores compatibility with Kokkos 4.x, preserving portability and stability of partitioned solvers, enabling smoother platform upgrades and paving the way for future performance optimizations. Technologies/skills demonstrated: C++, Kokkos API adaptation, cross-library collaboration (Ifpack2 and Phalanx), API-version readiness and maintenance across repositories.

April 2025 monthly summary: Implemented cross-repo dependency alignment for Trilinos with Kokkos 4.6.00. In spack/spack-packages, updated Trilinos dependency to Kokkos and Kokkos-kernels 4.6.00 to improve compatibility with newer core dependencies. In spack/spack, updated Trilinos dependency similarly to enhance build compatibility on master. These changes reduce upgrade risk, streamline future merges, and improve user build reliability.

March 2025 (2025-03) monthly summary for trilinos/Trilinos. Focused on improving portability and reliability through Kokkos compatibility fixes, core library refinements, and enhanced testing infrastructure.
