Introduction Wind energy accounts for over 8% of global electricity generation (IEA, 2025). Accurate modeling of wind flow across complex terrains and large turbine arrays remains challenging due to the multiscale nature of atmospheric turbulence. Traditional models often run on 32-bit architectures or legacy codebases, limiting domain size and real-time applicability.

Author: [Your Name] Affiliation: [Your University / Research Institution] Date: April 14, 2026 Abstract As wind energy penetration increases globally, the need for accurate, high-resolution, and computationally efficient wind flow models becomes critical. Existing 32-bit legacy systems suffer from memory addressing limitations and reduced numerical precision, hindering large-eddy simulations (LES) and real-time ensemble forecasting. This paper introduces Wind64 , a 64-bit computational framework designed specifically for mesoscale to microscale wind modeling. Wind64 leverages 64-bit memory addressing to handle grid sizes exceeding (10^9) cells, double-precision arithmetic for improved solver stability, and parallel I/O for petabyte-scale meteorological data. We present the system architecture, numerical methods, benchmark tests against the Weather Research and Forecasting (WRF) model, and a case study of a 200-turbine offshore wind farm. Results show a 4.2× speedup in simulation time and a 37% reduction in mean absolute error for wake-loss predictions compared to 32-bit baselines. Wind64 offers an open-source, scalable solution for next-generation wind resource assessment and operational forecasting. wind64

The transition to 64-bit computing in other domains (e.g., genomics, climate modeling) has enabled simulations with higher fidelity. However, a dedicated 64-bit wind modeling framework has been lacking. This paper proposes , a purpose-built software stack that exploits 64-bit address space and instruction sets (e.g., AVX-512) to overcome prior constraints.
