March 2025 achievements focused on enhancing MaCh3 DUNE near-detector simulations, stabilizing and upgrading build/dependency management, and improving code quality and documentation. Key progress includes Near Detector support for MaCh3 with ND interaction modes and sample configurations for FHC/RHC beams, plus updates to the SamplePDF base class to handle ND parameters (ND functionality stabilized: committed as 'Get the ND working again..'). Build system enhancements include improved installation layout (binaries installed to bin) and ensuring lib64 is in the library path, along with upgrading MaCh3 core library to v1.4.8. Extensive code quality, configuration, and documentation cleanups were performed (YAML formatting, README improvements, and linting fixes). These efforts deliver more accurate near-detector simulations, streamlined deployment, and improved maintainability and collaboration for future work.

February 2025 performance-driven consolidation across MaCh3 repos, delivering runtime and stability improvements through oscillator optimization, plus configuration-driven binning enhancements and a controlled dependency strategy to ensure reliability across releases. Key work focused on two repositories: - mach3-software/MaCh3: implemented NuOscillator integration improvements to reuse a single NuOscillator per samplePDF when binning is equal across oscillation channels, added a configuration option for this optimization, and introduced a per-channel EqualBinningPerOscChannel flag. Also fixed a minor error message typo related to configuration keys and upgraded NuOscillator to v1.2.0 for stability and compatibility. - DUNE/MaCh3_DUNE: added Oscillation channel equal binning configuration via EqualBinningPerOscChannel, with build-system alignment by updating the CMake tag to a new feature branch for optimizations; rolled back to the stable dependency version v1.3.5 to ensure reliability across releases.

January 2025 performance summary for DUNE MaCh3-related work. Delivered a set of build, integration, and quality improvements across two repositories (DUNE/MaCh3_DUNE and mach3-software/MaCh3) that enable easier upgrades, better memory safety, and more robust data processing. The work focused on upgrading dependencies to core library v1.3.x, modernizing the build system to align with upstream cmake standards, enabling Beam PDF samples, and improving error handling and metadata enrichment to support reliable data analysis.

2024-11 Monthly Summary for mach3 software projects: Key features delivered: - OscProb integration and OscProb calculator: integrated with NuOscillator in MaCh3; enable build integration, NuOscillator dependency alignment (main branch, v1.0.3), and updated user-facing documentation (README). - 1D Var histogram generation for analysis: added get1DVarHist in samplePDFFDBase to produce a weighted 1D histogram for a specified variable under given criteria. - OscProb Engine integration in NuOscillator (DUNE/MaCh3_DUNE): pulled core with access to the OscProb engine to enable shared OscProb functionality within the project. - MaCh3 core dependency stability: reverted to a stable older commit to facilitate debugging and ensure compatibility with newer core code. - ROOT dependency upgrade in setup: updated setup to pull ROOT 6.28.12 to use a newer patch release. Major bugs fixed: - Reverted MaCh3 core dependency to a stable commit to improve debugging stability and interface compatibility with the newer core code. Overall impact and accomplishments: - Enabled end-to-end OscProb-enabled neutrino oscillation calculations across MaCh3 and DUNE MaCh3_DUNE, improving analysis throughput and result reproducibility. - Strengthened build reliability and environment alignment through dependency stabilization and ROOT upgrade, reducing setup drift. - Expanded analysis capabilities with 1D Var hist generation for targeted variable studies, supporting more precise selection criteria and weighted analyses. Technologies/skills demonstrated: - Dependency management across NuOscillator and ROOT, build-system integration, and cross-repo orchestration. - OscProb engine integration and neutron oscillation calculator embedding into existing pipelines. - Histogram-based analytics development and documentation.

October 2024 highlights: Delivered a critical bug fix and compatibility update for DUNE/MaCh3_DUNE, addressing cross-section parameter iteration and alignment with the evolving core development branch. Specifically, replaced iteration over cross-section parameters to use getNpars() instead of getSize(), resolving parameter handling issues, and updated the StandardRecord include path to maintain compatibility with the latest core codebase. The changes enabled a clean build against the core development branch, reducing integration risk and accelerating downstream work. This work positions MaCh3_DUNE for smoother upstream merging and long-term maintainability.
