Worked on the gyselax/gyselalibxx repository, delivering an in-situ diagnostics and I/O performance testing application for a 5D distribution function, leveraging C++, GPU programming, and MPI for scalable parallel workflows. The implementation included GPU-based initialization, fluid moment computation, MPI transposition, and data export to NETCDF files for downstream analysis. Addressed CI stability by refining configuration management, specifically updating the typo checker’s ignore list to prevent false positives. Later, streamlined the core library by decoupling the mini-app into its own repository, improving maintainability and enabling independent release cycles. The work emphasized robust data I/O, repository management, and version control.

Mar 1, 2026March 2026: Core library (gyselax/gyselalibxx) was streamlined by decoupling the mini-app into its own dedicated repository, reducing core surface area and enabling independent evolution. The change improves maintainability, lowers integration risk, and supports faster release cycles for both the core library and the mini-app. No additional defects were reported in the scope of this work.

Jan 1, 2026January 2026 monthly summary for gyselax/gyselalibxx: Delivered an in-situ diagnostics and I/O performance testing app for the 5D distribution function. Implemented GPU initialization of the 5D function, computation of fluid moments, MPI transposition for parallel processing, data exposure on the CPU via PDI, and writing results to NETCDF restart files for downstream analysis. This feature-focused month established end-to-end in-situ diagnostics, enabling faster, scalable analysis workflows. No major bugs fixed this month; effort concentrated on feature delivery and integration. The work was conducted with contributions from Philipp Krah and Emily Bourne; commit 5fe6d46fbe4aed2c65009b261a4a9c22cf74f908 documents the implementation.
