Jan 1, 2026January 2026 monthly summary for arcaneframework/framework. Focus on delivering accelerator features, stabilizing CI, and consolidating the core codebase to support CUDA/HIP/SYCL backends and cooperative parallelism. Highlights include ensuring accelerator tests are always compiled when Google Test is available, renaming PropertyImpl::Property to FieldProperty with a related core move to Arccore, expanding test coverage with Float128 literals, advancing grid-stride support with StridedLoopRanges and RunCommand improvements, and implementing CI reliability improvements including repeating failed MacOS tests. These changes reduce risk, improve feedback loops, and prepare the codebase for cooperative launch and broader accelerator support.

Jul 1, 2025July 2025 performance summary: Delivered targeted features to harden component usage, expanded test coverage, and strengthened cross‑platform build stability. Key deliveries include a new ArcaneHdf5Register class to enforce the arcane_hdf5 component, and forced loading of arcane_hdf5 in tests to validate test-suite behavior. Fixed critical I/O/string handling issues (HDF5 string handling via String:bytes()), and consolidated test reliability by adding RunCommand::setParallelLoopOptions() tests while suppressing the experimental API warning to reduce noise. CI/build and configuration improvements included updating the compile-all-vcpkg workflow to v1.9.1, introducing the ARCANE_FORCE_NOASNEEDed option, and ensuring arcane_driver is installed in lib across configurations, with tests verifying arcane_driver usage. Additional cross-cutting enhancements in Python integration, memory utilities, and post-processing tag naming contributed to developer productivity, reliability, and end-to-end automation.

Feb 1, 2025February 2025 Monthly Summary for arcaneframework/framework: Deliverables focused on core architecture refactor, broader namespace alignment, and foundational feature work to enable scalable performance and easier maintenance. The team completed several high-impact extensions across Arcane and Arccore components, plus targeted bug fixes to improve stability and compatibility. Key achievements and deliverables: - ArcCore integration and library hygiene: relocated and cleaned Arccore using directives across arcane/core; consolidated usage; ArcaneMpi.h usages moved to Arccore. Representative commits include: 6e148dd0 (move Arccore from arcane/core), 7520ca58 (remove remaining Arccore::* usages in Arcane), 867c1d06 (centralize ArcaneMpi.h usage). - FaceReorienter consolidation: moved FaceReorienter into Arcane core and removed dependency on FaceFamily; codebase now uses Arcane/core path instead of mesh-specific placement. Commits include: d2b0f8db, 4b20ae34, 41a091da. - New conversion utilities and tests: added ItemLocalIdToItemConverter to convert ItemLocalId to Item with mesh usage tests; extended tests for ItemLocalIdToItemConverter. Commits: eedf61d5, 9111b4ba, 1c6829c3. - Item type constants and tests: introduced ItemTypeId constants with corresponding tests to validate new constants. Commits: a153dc53, a632c449. - Parallel/file propagation and topology improvements: published missing arcane/parallel files to ensure complete build; added IItemFamilyTopologyModifier::setBackAndFrontCells() API. Commits: 1bacc40b, 5a3e79ec. - Namespace and internal API refactor: Arcane namespace refactor of Arccore core components, including MessagePassing, serialize, concurrency, collections, trace, base, and impl details; relocation of several Arccore internal modules into Arcane namespace. Representative commits: 3bc10014, 7bcbbfe8, d6dc2a6e, 7c7239a6, ad3e3958, 9f2ea3e1, 5fc68bb2, 8b871dd2, 01b79bec. - VtkHdf support and tests: started support for post-processing constituents in VtkHdf format with accompanying tests. Commits: 64cce611, 74917558. - HDF5 and compatibility improvements: fixed HDF5-related compilation across GCC/MSVC variants; naming consistency adjustments for IT_* identifiers; improved header usage across modules. Commits: 45cbb1a4, 993c88a1, e7d7064e, 48f4d153. - Internal API and utility refinements: serialize message relocation and internal usage updates; misc internal improvements including renamed types and memory utility helpers; RunQueueEvent enhancements for pending work reporting; tests migrated to gtest for Event. Representative commits: f8be3997, d1c9e5d5, 4ae0e093, eccafc75, c886be45, b3efd3ab, e43e36a7, 48790d4c. Major bugs fixed and quality improvements: - Copyright and header consistency fixes across Arcane and Alien modules; internal API mismatches resolved (e.g., Include Arccore headers vs. defined types); removal of deprecated MpiSerializeMessageList and related tests. - ArrayView and BasicSerializeMessage dependencies cleaned up to reduce build fragility. - Build compatibility: HDF5-related compilation issues resolved for multiple toolchains. - Event and RunQueue related stability improvements and test diversification (gtest-based tests). Overall impact and business value: - Architectural refactors reduce long-term maintenance cost by aligning Arccore and Arcane namespaces, reducing cross-module dependencies, and centralizing core utilities. This enables faster feature delivery, easier onboarding, and better testability. - Feature work unlocks more robust parallel and MPI-capable paths, improved deterministic ordering, and accelerator-ready data structures, which boost performance and scalability for large-scale simulations. - Improved stability and compatibility across compilers and platforms, reducing build failures and accelerating CI feedback cycles. Technologies/skills demonstrated: - C++ best practices: namespace realignment, internal API design, reference/ownership handling, and utility encapsulation. - Testing maturity: increased test coverage for converters, constants, and event utilities; migration to gtest for Event tests. - Performance and memory management awareness: memory resource handling improvements, accelerator support planning for MultiArray2, and optimizations in sorting and parallel utilities. - MPI/Parallel: migrating internal MPI-related APIs to internal APIs and refining MPI control dispatching patterns.
