Jul 1, 2025July 2025 — ExtremeFLOW/neko: Delivered targeted improvements across the interpolation workflow, build reliability, and device kernel precision. Key changes include refactoring fld_generate_interpolator to a subroutine with pass-by-reference semantics for in-place updates, a HIP build flag typo fix to restore clean HIP backend builds, and introduction of a real_xp data type for higher-precision device computations. These efforts improve maintainability, reduce build-time failures, and enhance numerical accuracy in GPU-accelerated simulations, delivering business value through more robust software, faster iteration cycles, and better fidelity in HPC workloads.
